Widely used in human body sensor switches, alarms, infrared thermometers and infrared imaging, and other aspects. It can provide users with different sensing angles, sensing distances, sizes, and test ratios. Fresnel lens function: first, focusing effect; The second is to divide the detection area into several bright and dark areas so that the moving objects entering the detection area can produce a change pyroelectric infrared signal on the PIR (passive infrared detector) in the form of temperature changes.

Feature:

1. The Mini PIR Plastic Housing PIR Sensor is a compact and lightweight motion detection device.
2. It is designed with a Fresnel lens which allows for greater accuracy in detecting movement.
3. The sensor has a diameter of 23mm and is ideal for use in small spaces.
4. The plastic housing ensures the durability and longevity of the sensor.
5. This PIR sensor can be used in a variety of applications such as security systems, lighting control, and energy management.
6. It operates on low voltage and has a low power consumption, making it energy efficient.
