HC-SR501 PIR Motion Sensor Module - (AD865)

Description:

This is an adjustable HC-SR501 human motion detection sensor module using infrared pyroelectricity.

TTL output is HIGH when people are detected, and LOW when they are not. When a person enters the projected area, the sensor's output will switch to a HIGH state; when the person leaves the projected area, after an adjustable delay, the sensor's output will switch to its LOW state.

Specifications:

- Input voltage: DC 4.5-20V

- Static current: 50uA

- Output signal: 0.3V or 5V (high output when motion is detected)

- Detection angle: 110 degrees

- Detection distance: max 7 m

- Trigger: H - Yes, L - No
