PIR Motion Module

This documentation includes hardware info, installation guidelines and sample code for your hardware.

Overall Info

Turta PIR Motion Detect Module recognizes the movement of heat-emitting things, like humans. It carries AM312 passive infrared sensor.


Module Connections

  • INT: Motion detect out.

  • POWER: +3.3V and GND.


AM312's technical specifications are as follows:

  • Detection range: Approx. 3m.

  • Delay time: 2.3 Seconds.

  • Two-way differential high impedance sensor input and temperature compensation.

  • Built-in filter, screen the interference by other frequency.

  • Operating temperature range: -20 to 85 °C

Compatible Hardware

PIR Motion Detect Module is an add-in board for Turta Modular System. You'll need a compatible host device for your module. The following devices support PIR Motion Detect Module:
