Sensors. If you’ve been in the IoT industry for a while now, you know that this is where it all begins. Before we delve into smart sensors, why they’re crucial and how to use them, here’s a short sensor brief. Sensors are our troops out in the field, and are used to detect and respond to electrical or optical signals. Sensors take parameters from the physical world (humidity, temperature, etc.) and turn them to signals that can be measured electrically.

What can we explore with sensors? So much out there to discover. Here are a few sensors that can help:

Moist: humidity sensors. Acceleration: Gyroscopes, Accelerometers. Temperature: Thermocouples, Thermistors, etc. Pressure: Fiber optic, vacuum, etc. Biosensors: Resonant mirror, electrochemical, etc. Image: CMOS.

In IoT, our sensors gather data from the physical world and send it to the cloud. This allows the revolutionary value of IoT – gathering analytics and insights from ANYTHING. But wait, it’s true that Google Analytics can gather data on your website 24/7, but how could this capability ever be possible in the physical unstable world? The need for accurate data collected in long periods of time has forced sensor manufacturers to go smarter.

Smart sensors make the IoT process more efficient. As previous sensors, they take input from the physical environment. When detecting a specific input, smart sensors preform predefined functions and process the data before passing it to the cloud. This enables the collection to be automated and in addition, the data is more accurate with less noise.

What makes a smart sensor smart?

A smart sensor is comprised of an integrated circuit (IC). The physical design includes a sensor, a microprocessor, a communication technology of some kind and compute resources. Wireless sensor networks are enabling the possibility to define functions in advance, as well as monitor and collect data. More accurate data, collected more efficiently, breaking long-standing barriers, leads to better decision making with less human effort.

As IoT sets new challenges and needs, smart sensors keep getting smarter, allowing more flexibility and efficiency. for more information, contact our team of experts: and visit the Atomation website.
