    • About this item

  • Working Principle: AM312 PIR motion sensor detects 10μm infrared radiation emitted by the human body through pyroelectric sensors. Temperature changes cause charge imbalance and release electrical signals. After the sensor signal is amplified and filtered, the chip determines whether there is a human body approaching and outputs a high/low level signal
  • Repeatable Triggering: After the sensor outputs a high level, within the delay time period, if a human body moves within its sensing range, its output will remain at a high level until the person leaves and then become a low level (that is, the sensor module will automatically extend a delay time period after detecting each human activity, and the time of the last activity is the starting point of the delay time)
  • Small and Practical: Small size (PCB size is only 10mm*8mm); high sensitivity, can detect tiny infrared changes, strong anti-interference ability; low power consumption, static power consumption is less than 0.1mA. IR sensor can be installed on ESP32, Arduino UNO/Nano/Mega, STM32, etc. Used for home automation and can work together efficiently
  • Widely Application: Small size, low cost, widely used in consumer and industrial scenarios. You can use this HC-SR312 PIR sensor in different occasions like security system, smart lighting, smart home, automation control, etc
  • Parameter: Working voltage: DC 2.7-12V; static power consumption: <0.1mA; delay time: 2 Seconds; blocking time: 2 Seconds; trigger mode: repeatable; sensing range: ≤100 degree cone angle, 3-5 meters (depending on the specific lens); working temperature: -20 - +60℃
