PIR Sensor and LCD Interface to Arduino : 5 Steps (with ...

Passive infrared radiationsensor shortly known as PIR sensor measures the radiation of infrared from its boundary , the object around us radiates infrared rays which are not visible to human but these sensors are designed for such there is a change in the temperature around its boundary the sensor sends a signal. PIR connection is as follows:


Arduino PIR Sensor Tutorial | PIR Motion Sensor with Arduino

12/1/2018· Since the Digital Out Pin of the PIR Sensor is either HIGH or LOW based on the movement detected, you can build a simple circuit to test the PIR Sensor. The first circuit consists of a PIR Sensor and an LED. When the PIR Sensor detects motions, the LED turns ON. The duration for which the LED is ON can be adjusted with the help of Delay Adjust POT.
