Hello friends, I hope you all are doing great. In today’s tutorial, we will have a look at What are Light Sensors and how to use them. Light sensors are such components that sense the surrounding light and transform it into the current. Such sensors are normally used in different applications such as switching circuits and for security purpose. When they used in different security circuits these sensors detect the variation in the light then they send the signal to the alarm.
There are numerous types of light detectors components but there operating principle is similar. The most commonly used types of light sensors are a light-emitting diode, photodiodes, infrared radiation (IR) detectors, etc. In today's post, we will have a look at working, fea ...
