PIR Motion Sensor Detector Module HC-SR501

If you want to build a device that is used to detect sense motion and almost always used to detect whether a human has moved in or out of the sensors range.
The PIR Motion Sensor Detector Module HC SR501 allows you to sense motion. It is almost always used to detect the motion of a human body within the sensorÕs range. It is often referred to using ÒPIRÓ, ÒPyroelectricÓ, ÒPassive InfraredÓ and ÒIR MotionÓ sensors.

The module has an onboard pyroelectric sensor, conditioning circuitry, and a dome-shaped Fresnel lens. It has a delay time adjustment Potentiometer and sensitivity adjustment Potentiometer. Compatible with ARDUINO, RASPBERRY PI, AVR, PIC, 8051, etc.

Features:

• Infrared Sensor with Control Circuit Board
• The Sensitivity and Holding Time are adjustable.
• Blockade time: 2.5s (Default)
• Sensitive Setting: Turn to Right, Distance Increases (About 7M); Turn to Left, Distance Reduce (About 3M)
• Time Setting: Turn to Right, Time Increases (About 200S); Turn to Left, Time Reduce (About 5S).

Package Includes:

• 1 x PIR Motion Sensor Detector Module HC SR501
