PIR Sensor Module Parts. The topmost part of the PIR sensor consists of a lens with concentric grooves carved into the plastic. These are called Fresnel lens.. The contours on this plastic helps in ...

In India, nearly 20 percent of the electricity is lost due to technical and commercial reasons. Three billion units of power are wasted every year. The Automation of lighting system with the usage of ...

This usually takes not less than 30 seconds. So a 30 seconds delay is intentionally included in the sketch. For other type of sensors this is not necessary, thence remember to delete the line delay(30 ...
