PIR motion sensor

The motion sensor (PIR sensor) is an electro-thermal sensor that detects the movement by sensing changes in the levels of infrared radiation emitted from  objects and transforming it into an electrical signal. it compatible with Arduino
It can sense the movement near it for a distance of 3 to 7 meters with a delay of at least 5 seconds. A plastic dome was added to it to increase the spread of the waves, and it senses the presence of movement at an angle of 110 degrees.
