HC-SR312 Pyroelectric Micro Infrared PIR Motion Sensor Module

This item is HC-SR312 human body induction module: it is a digital intelligent automatic control product based on  passive human body infrared technology, with high sensitivity and reliability. It is widely used in all kinds of automatic induction electrical equipment.


  • Low power consumption, small size, easy for embedded installation
  • Internal digital signal processing, anti-interference enhancement
  • High sensitivity and high reliability, can be widely used in automatic sensing circuit technical parameters
  • Anti-interference enhancement, internal use of
  • digital signal processing, direct high and low level output
  • Repeatable trigger mode: after induction output high level, the time delay period, if there is the human body in the scope of its induction activities, its output will always keep a high level, until the people left after the delay, it becomes low level (that is, the sensing module automatically delays a delay period after detecting each activity of the human body, and takes the time of the last activity as the starting point of the delay time).
