Product Description
Passive Infra-Red (PIR) sensor is a motion detector sensor by measures changes in the infrared levels emitted by surrounding objects. It gives a HIGH signal at the I/O pin when motion is detected. Usually used as a security device in a monitored area (such as a room or hall) to detect the appearance of a human being.
Features of PIR Motion Sensor:
Operating voltage: 4.5 to 20V DC
Single-bit output (digital)
Delay time adjustable
Compatible with all types of microcontroller
The small size makes it easy to conceal
Plug n Play feature
Model: HC-SR501
