HC-SR501 Pyroelectric Infrared PIR Motion Sensor Detector detection Module

PIR sensor for Arduino,They are small, inexpensive, low-power, easy to use and don’t wear out. For that reason they are commonly found in appliances and gadgets used in homes or businesses. They are often referred to as PIR, “Passive Infrared”, “Pyroelectric”, or “IR motion” sensors.

Technical parameters:

1 Operating voltage: DC5V to 20V

Static power consumption: 65 microamps

3-level output: 3.3V, low 0V

Delay time: adjustable (0.3 seconds to 18 seconds)

5. Blockade time: 0.2 seconds

Trigger: L can not be repeated, H can be repeated, the default value of H

Sensing range: less than 120 degree cone angle, 7 meters

Operating Temperature: -15 to +70 degrees

9.PCB Dimensions: 32 * 24mm, screw hole distance 28mm, screw aperture 2mm sensor lens size: (diameter): 23mm (default)

Along with the pyroelectic sensor is a bunch of supporting circuitry, resistors and capacitors. It seems that most small hobbyist sensors use the BISS0001 (“Micro Power PIR Motion Detector IC”) , undoubtedly a very inexpensive chip. This chip takes the output of the sensor and does some minor processing on it to emit a digital output pulse from the analog sensor.
