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.
