Hardware & Sensors

Sensors are sophisticated devices capable of detecting or responding to electrical or optical signals. They convert physical parameters such as temperature, pressure, humidity, speed, etc. into a signal that can be measured electronically. In this section, we will discuss sensors and how they revolutionize so many other technologies.
