    • What Are Wireless IoT Sensors and Why Are They Useful

    2021-05-16

    What Are Wireless IoT Sensors and Why Are They Useful? The Internet of Things (IoT) is transforming our world in tremendous ways.  By enabling everyday objects to communicate wirelessly, we can automate data exchange and create new efficiencies that positively impact lives and organizations. Underlying the IoT is wireless sensor technology, which allows us to collect information about surrounding environments over extended periods with little manual effort. Wireless sensors can be configured to measure a variety of variables, from air temperature to vibration. Overall, there are many different types of wireless sensors available in the marketplace.  Many wireless networks contain hundreds, sometimes thousands, of wireless sensors. Already, these devices are used across a wide range of sectors, including retail, agriculture, urban planning, security, and supply chain management.  In this article, we dive deeper into how wireless sensors work and explain why they’re so important for the IoT revolution. What Do Wireless Sensors Do? Wireless sensors gather data about local conditions and share findings with other powerful components or platforms for further processing. Sensors are typically distributed across large geographic areas and programmed to communicate with central hubs, gateways, and servers.  One major advantage of wireless sensors is they require a low level of maintenance and a small amount of power to function. Sensors can support IoT applications for years before needing a battery change or charge. When it comes to building wireless networks, one of the biggest questions developers face is how to arrange wireless sensors in the field. Sensors, or “nodes,” must be distributed in such a way that supports the overarching objective of the network developer. How Are Wireless Sensors Networked? The two most common arrangements for wireless sensors are the star and mesh topologies. The “mesh” topology describes networks in which sensors connect to as many other nearby nodes...

    What is IoT

    2021-05-15

    What is the Internet of Things, or IoT? A Simple Explanation. The Internet of Things, or "IoT" for short, is about extending the power of the internet beyond computers and smartphones to a whole range of other things, processes, and environments. Here's everything you need to know. The Internet of Things (IoT) market continues to grow with the increasing number of connected devices. These connected, or “smart,” devices can be found in every industry you can think of, such as manufacturing, healthcare, and agriculture. You’ve probably encountered smart devices in your own home, even! Still, it might seem hard to picture how these devices make up the larger ecosystem that IoT is. You may be wondering, what is IoT, exactly? Although IoT is very vast, this is everything you need to know about the Internet of Things the next time a friend or a coworker mentions their smart cars, watches, or doorbells. What is IoT? If you just Google “What is IoT?” many of the answers are unnecessarily technical. Case in point: “The Internet of Things (IoT) is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.”—An unnecessarily technical explanation of IoT If you’re confused, you’re not alone if you’re confused. Most people neither want nor need to dive into the nitty-gritty of IoT. In this post, I’ll provide you with a simple explanation of the Internet of Things and how it works. Before we jump in, note that “The Internet of Things” and “IoT” can and will be used interchangeably. IoT Explained: Simple and Non-Technical You might be reading this on desktop or tablet, but whatever device you’re using, it’s connected to the internet....

    IoT Security in the Era of Remote Work

    2021-05-08

    IoT Security in the Era of Remote Work? Arguably one of the largest corporate impacts of the pandemic is the shift in working habits and thus remote work IoT security. At the height of lockdown restrictions, remote working became the norm, and this continues to be the preferred working model for many employees even as offices have begun to open back up. For example, according to a recent Pew Research, 76 percent of employees who are working from home cite their preference as their primary reason for doing so. Post-Pandemic Remote Work As employees and employers alike settle into remote working for the long-term, it’s important that they stay abreast of emerging security concerns. When the abrupt pivot to the remote model happened two years ago, both enterprises and employees scrambled to ensure everyone and everything was connected. In the chaos, security was often an afterthought, but companies have an opportunity today to eliminate any lingering vulnerabilities and ensure a more secure remote model. IoT Security Concerns When the majority of workers operate out of a physical location, there are generally robust security procedures in place. It’s not always possible—or practical—to implement these when employees are working remotely. In addition, the WFH model introduces its own security concerns, ranging from weak passwords on personal computers, poorly secured wi-fi, or the family’s Alexa passing along malware. So, what can be done to address these vulnerabilities? Some helpful tips for both IT departments and employees include: Network Security Network security is another important consideration. Employees may be cognizant of security best practices in the office, but it’s not unusual for them to be much less vigilant at home. Companies with remote staff must educate them on home network risks, including the fact that many household products like baby monitors or smart TVs can introduce numerous security...

    What Is a Smartwatch

    2020-07-09

    What Is a Smartwatch and What Do They Do? Everything you need to know about smartwatches A smartwatch is a portable device that's designed to be worn on a wrist. Like smartphones, they use touchscreens, offer apps, and often record your heart rate and other vital signs. The Apple Watch and Wear (formerly Android Wear) models prompted more consumers to appreciate the usefulness of wearing a mini computer on their wrists. In addition, specialty smartwatches for outdoor activities often supplement other, bulkier devices in an adventurer's tool kit. A Short History of the Smartwatch While digital watches have been around for decades—some with abilities like calculators and unit converters—only in the 2010s did tech companies begin releasing watches with smartphone-like abilities. Apple, Samsung, Sony, and other major players offer smartwatches on the consumer market, but a small startup actually deserves credit for popularizing the modern-day smartwatch. When Pebble announced its first smartwatch in 2013, it raised a record amount of funding on Kickstarter and went on to sell more than one million units. At the same time, advances in silicon miniaturization opened the door to other kinds of dedicated-purpose smartwatches. Companies like Garmin, for example, support smartwatches like the Fenix, which are more rugged and optimized with sensors and trackers to support back-country expeditions. Likewise, companies like Suunto released smartwatches optimized for scuba diving that withstand extended time at significant depths. What Do Smartwatches Do? Most smartwatches—whether they're intended for daily use (as with the Apple Watch) or for specific purposes (as with the Garmin Fenix)—offer a suite of standard features: Types of Smartwatches Broadly speaking, smartwatches occupy two niches in the wearables market. First, a general-purpose smartwatch—like the Apple Watch and most Google-powered Wear devices—blend form and function. They're designed to replace mechanical wristwatches and are heavily smartphone-dependent. Think of them...

    Six Exciting IoT Applications in Healthcare

    2020-06-19

    Six Exciting IoT Applications in Healthcare You’ve probably heard of the Internet of Things (IoT) and how it’s changed how we manage things like our utilities and home security, but IoT is capable of so much more. Much of healthcare is reliant on human labor for tasks that are highly repetitive, manual, and often tedious. IoT has the power to not only significantly reduce operational costs for the healthcare industry, but improve patient care and save lives. Check out these six examples: 1. Reducing Emergency Room Wait Times Few things are as dull and boring as a visit to the emergency room. Apart from the resulting medical expenses, emergency room visits can sometimes take hours to complete. Thanks to some recent ingenuity and the IoT, at least one hospital — Mt. Sinai Medical Center in New York City — effectively slashed wait times for 50% of their emergency room patients who are in need of inpatient care. It’s their partnership with GE Healthcare and new, IoT-driven software, known as AutoBed, that tracks occupancy among 1,200 units and factors in 15 different metrics to assess the needs of individual patients. It’s a highly effective system that highlights some of the more innovative and exciting uses of the IoT. 2. Remote Health and Monitoring In some cases, patients don’t even have to visit an emergency room or hospital. One of the most obvious and popular applications of healthcare and the IoT is in remote health monitoring — sometimes known as telehealth. Not only does it minimize costs and eliminate the need for some visitations, but it helps improve the patient’s quality of living by sparing them the inconvenience of travel. If a patient has limited mobility or depends on public transportation, something as simple as this can make a world of difference. 3. Ensuring the Availability and Accessibility of...

    New way of connecting things

    2019-05-13

    NB-IOT:New way of connecting things Over the past few decades, the number of objects (things) connected to the internet has grown exponentially. And with the everyday development of technology, the Internet of things (IoT) has penetrated in almost every application area. It has revolutionized the way machines interact and provided cutting-edge solutions to a variety of real-life problems. As the IoT in itself is a large hood, covering almost every sphere of technology nowadays, we will be focussing  our discussion on Narrow Band Internet of Things (NB-IoT) in this article.  We will be exploring  NB-IoT and how it is impacting the volume of connected devices and IoT connectivity infrastructure. What all we have already? In order to connect sparsely deployed IoT devices, the present short range communication technologies like BLE, ZigBee, WiFi are not a viable solution. To get over this limitation, several Wide Area Network (WAN) technologies have been evolved such as LoRaWAN (Long Range WAN), SigFox, LTE-CatM and NB-IoT. Since these technologies are meant for low powered battery operated devices, we name them as Low Power Wide Area Network (LPWAN) technologies. The four key features of LPWAN technologies are Long range, low power consumption, low throughput  and low cost. As there are many LPWAN technologies, it’s very interesting to see how NB-IoT stands out. LPWAN provides voice to objects by enabling them to communicate. Consider a dustbin which is full and needs to be emptied. Using LPWAN technology, a dustbin can send a message to the user, “I am full, please empty me”, which in turn can ensure timely garbage clearance and avoid periodic manual checks on the other hand. Where does the problem lie? Existing cellular infrastructure and internet connectivity is designed keeping the humans at the centre point to fulfil their different data requirements. IoT devices...

    Top On-Site Tests for Watches

    2019-04-09

    Top On-Site Tests for Watches In the watch industry, quality is paramount and Vositone, as an expert manufacturer, maintains a high standard of quality assurance (QA) processes from pre-production to post-production. There are three phases involved in our watch manufacturing quality control protocol: Incoming Quality Control (IQC) To ensure the quality of essential components, we employ rigorous testing that focuses primarily on a watch's main parts – dial, case, and strap. DialsDials are tested for ultraviolet (UV) resistance (UV Rays Test). This is done by applying an alloy paper over the dial in a half-covered position before placing it under the light of a UV machine. This determines if any dials show discoloration within 72 hours. CasesAn Abrasion Test determines cases’ resistance to scratches. The usual process involves tumbling the cases in a coarse mixture of materials that can cause abrasion. This test checks for corrosion and scratches to the metals. A separate Cases Condensation Test follows to examine if the cases meet waterproof standards by heating up the cases before placing them on cold plates and checking for any internal condensation. StrapsA common test for straps is the Tension and Torsion Test. Here, the leather straps are continuously folded, stretched, and twisted using two different machines. Metal bracelets are checked using a separate machine where the cuffs are repeatedly shaken (also known as the Swing Test). All tests check the flexibility of leather straps and the sturdiness of metal bracelets. In-Process Quality Control (IPQC)During manufacturing, a series of follow-up tests are added in the process to guarantee quality. As a smartwatch manufacturer, for instance, the Hands Test confirms whether the watch’s hands are in the proper parallel alignment by careful examination using an HD monitor. Outgoing Quality Control (OQA)Before the final packaging and shipping, all watches are subjected to final inspection....
