PIR Motion Sensor HC-SR501

(Passive Infra-Red) A PIR Motion 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
• Made in China
