Motion Sensor
This Motion/ PIR Sensor Switch Can Detect the Infrared Rays released by Human Body Motion within the Detection Area (6 Meters). The PIR (Passive Infrared) sensor can sense even at night time.
The sensor can fixed near the door to check the motion near to the door.
So if some one enters into the detection area of the sensor, the microcontroller will read it and inform the mobile and you can hear a voice alarm "Motion Detected"
