Hello, welcome back. In this tutorial, we will talk about a sweep hand sensor switch module. This sensor is mainly based on IR diodes. Also, no programming knowledge is required to work with this sensor. That is, anyone can carry out projects using this sensor. We can get an output potential by moving your hand above the sensor. This is described below. Also, we can use this sensor mainly to control the electrical appliances in the house. This tutorial explains how sensors work using an LED. Once you understand the basic principle here, you can connect any device you want.
The structure of this sensor switch
This sensor is very small, and it is designed using two IR diodes. That is, one IR diode emits IR rays and the other IR diode captures these IR rays. Due to this process, when an object moves above the sensor, we can get a voltage as the output. This voltage is the same as the supply voltage. Also, this sensor works like a normal switch. That is, we can get the same voltage given to this sensor as an output. Remember to give a voltage of 3 to 12. Also, the sensitivity range is between 10 – 80mm. Therefore, it is more suitable for projects that require short distances.
