Human Body Sensing Module PIR Module Infrared Module Infrared Human Body Sensor PM-2 Pyroelectric

PM-2 pyroelectric Human body infrared sensor module

 Model: PM-2
Sensing distance: High sensitivity range 0-5 meters, output high level,3.3V
Sensing distance: Low sensitivity range 0-2 meters, output high level,3.3V
Power supply DC: 3.3V-10V
Static current: 100uA

Purpose

    Human body sensor lights, alarms, security systems, access control cameras as needed, automatic detection in agriculture, forestry and mining, etc.

    This module features high sensitivity, fast response speed, low static power consumption, compact size, and easy installation. The lens is already installed and the header pins are soldered. Once equipped with a power supply, it can be used without any debugging.

Explanation

  1.The high-level output time of this product is adjustable within the range of 1 second to 300 seconds, with 12 Settings. The output time set at the factory is 1 second. If you need to change it, please communicate with customer service. (Optional: 1,5,10,15,20,30,45,60,90,120,180,300 seconds)
  2.The power supply voltage of this module ranges from 3.3V to 10V.
  3. The module comes with a matching black lens. If you need a black lens, please communicate with the customer service. By default, the lenses delivered will be milky white.
  4. After being powered on, the IC chip has a self-check process of about 36 seconds. During this process, there is a high-level output, and then it enters a stable working state.
  5. After installing the photosensitive element, it does not work during the day and works at night. Without installing the photosensitive element, it works all day long.(The photosensitive element was not installed when sold.)

  6. This module is very sensitive. Pay attention to the installation position and try to avoid heat sources/radiation sources (air outlets/direct sunlight). The Fresnel lens and the finished housing (the iron shell/circuit board of the sensor must not be exposed) must be installed first before conducting the test; otherwise, the sensing effect will be poor and false actions may occur due to wind.

  7. It is factory-defined as repeatable and unalterable.
  8. The sensitivity of this module is adjustable. (Replace one or two surface mount resistors.) It can be adjusted from 0.5 meters to 5 meters.
   9. This module has requirements for power supply. Dry batteries, lithium batteries, or DC regulated power supplies can be selected for testing. Mobile phone chargers, carbon 9V stacked batteries, power banks, and computer USB power supplies are all applicable. The power supply
