PIR Sensor is also called as Motion Sensor or Movement Sensor or is basically a Passive Infrared Sensor. It is a pyroelectric device that detects motion by measuring changes in the infrared levels emitted by surrounding objects. This motion can be detected by checking for a high signal on a single I/O pin. It detect the  motion by detecting the changes in the IR levels emitted from the object.It can be used as motion detector for security systems or robotics. 
It works from 3.3V to 5V DC and gives TTL output which can be directly given to Arduino, Raspberry Pi or any other microcontroller or to relay through a transistor
