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.

  • Low power consumption, small size, easy to install
  • Internal use of digital signal processing, pit interference strong
  • High sensitivity, reliability, and can be widely used in the automatic sensing circuit
  • Repeatable trigger mode: that is, after the induction output is high, in the delay period, if the body in its induction range of activities, the output will remain high until the delay after the person becomes Low level.  (Ie, the sensing module automatically detects a delay period after each activity of the human body, and takes the last active time as the starting point for the delay time).
