Turta PIR Motion Detect Module recognizes the movement of heat-emitting things, like humans. It carries AM312 passive infrared sensor.
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
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:
Turta IoT Node - ESP32
Turta Modular HAT for Raspberry Pi
