An Introduction to IoT Sensors

| March 5, 2020

This post will cover various important sensors that are possibilities for an IoT deployment. Sensors are the backbone of any IoT deployment. They gather information and provide software with sensory information it needs to achieve its full potential. In addition, this post will go over considerations and decision-making for selecting sensors in an IoT deployment. Often times, a single sensor is not the best implementation, a suite of sensors can gather more data and even affect behavior for other sensors. In many cases, more than one sensor is necessary to perform the IoT deployment’s function. Sensors are just as critical to every IoT application as the internet. Imagine Alexa or Google Home without a microphone: it wouldn’t work. People wouldn’t be able to interact with the device, or it would need some other kind of sensor such as a keyboard to obtain input from a user.

Which IoT Applications will Benefit Most from Edge Computing?

Article | March 2, 2020

Edge computing refers to information being processed at the edge of the network, rather than being sent to a central cloud server. The benefits of edge computing include reduced latency, reduced costs, increased security and increased business efficiency. Transferring data from the edge of a network takes time, particularly if the data is being collected in a remote location. While the transfer may usually take less than a second, glitches in the network or an unreliable connection may increase the time required. For some IoT applications, for example, self-driving cars, even a second may be too long. Imagine a security camera that’s monitoring an empty hallway. There’s no need to send hours of large video files of an empty hallway to a cloud server (where you will need to pay to store them). With edge computing, the video could be sent to the cloud only if there is movement detected in the hallway.

Internet of Things (IoT): The Need for Vendors to Address Security

Article | March 3, 2020

By the end of this year there will be 5.8 billion Internet of Things (IoT) endpoints, according to Gartner. And depending on how IoT devices are counted the number is even higher. Statista, for example, estimates the device count for 2020 to be more than 30 billion. Security remains a big challenge for IoT as a strategy to be successful. IoT devices are still not being designed with security as a top priority.Mary O’Neill, VP of security at Nokia, noted in a press conference at MWC Los Angeles 2019 and reported by SDXCentral, that “if an IoT device today is plugged into the network and it doesn’t have protection on it, it’s infected in three minutes or less.”Jake Williams, founder of the security firm Rendition Infosec, said that “IoT vendors emphasize, often rightly, that their products improve quality of life, but they often neglect to disclose the risk of these devices to consumers. The onus of understanding how an IoT device might impact security should not be purely on the consumer. The vendor shares this responsibility.

Frailties of LoRaWAN IoT Devices

Article | March 5, 2020

Low-power wide-area networks (LPWANs) are helping drive the Internet of things (IoT) explosion. They connect millions of low-power IoT and Industrial IoT (IIoT) devices into wireless networks over a range of distances, from short to really, really long, from indoor applications to those covering large fields or even cities. But device designers using the LoRaWAN standard may be lulled into thinking that just configuring its security keys is enough to prevent their devices from being hacked. A new report says it isn’t. Four protocols give enterprises a choice in LPWAN connectivity: cellular NB-IoT, LTE-M, and Sigfox, and the non-cellular LoRaWAN standard. Among these, the open LoRaWAN overwhelmingly dominates. Omdia (formerly IHS Markit – Technology) projects a “quite high forecast” for LoRa, said Lee Ratliff, senior principal analyst, connectivity and IoT.

Advantages and Disadvantages of Implementing IoT in Healthcare

Article | March 17, 2020

Given such examples, the Internet of Things (IoT) is seen as a way of living a smarter and safer life and its application is highly encouraged in medical establishments. However, digital transformation in healthcare isn’t without threats. It’s important to weigh all the advantages and disadvantages of implementing IoT systems in healthcare to be able to plan for ways to maximize the pros while mitigating the cons.
