Mini IR Infrared Pyroelectric PIR Body Motion Human Sensor Detector Module AM312 Sensor
The AM312 is a compact pyroelectric passive infrared (PIR) sensor module designed for detecting human body motion. It senses changes in infrared radiation caused by moving people or animals, outputting a digital signal when motion is detected. Its low power consumption, small size, and high sensitivity make it ideal for compact, energy-efficient motion-sensing applications.
The AM312 PIR Motion detection sensor is a passive body based on digital intelligent infrared technology. These sensors have high sensitivity and high reliability. They are widely used in various auto-sensing electrical equipment.
AM312 PIR Motion detection sensors are mostly used to detect whether a human has moved in or out of the sensor’s range. They are small, inexpensive, low-power, easy to use, and don’t wear out. They are often referred to as PIR, “Passive Infrared”, “Pyroelectric” or “IR motion” sensors.
