IoT: How Good are Our Sensors?

January 05, 2020 / Tech Native

It is found by market researchers that more than 20 billion of our devices are connected. Right from our smartphones, smartwatches and several other devices that we use in our day to day lives, are powered by sensors. These sensors play a vital role and they monitor our air quality, health status, home security, and are most widely used in industrial IoT. Before jumping into depths about IoT and sensing, let us take a look at what are sensors. In general terms, a sensor is a tool capable of detecting environmental changes. A sensor alone is useless, but it plays an important role if we make use of it in an electronic device. A sensor can measure and transform an electrical signal into a physical process such as pressure, temperature, and so on.
