The AM312 Mini PIR Motion Sensor is a compact passive infrared sensor designed to detect motion within a 3–5 meter range and a 100-degree cone angle. Operating at DC 2.7–12V with static power consumption below 0.1mA, it features a 2-second delay and repeatable trigger mode. The sensor is compatible with a wide range of electronic projects and microcontroller platforms, offering reliable performance in temperatures from -20 °C to +60 °C. Its small PCB (10 mm × 8 mm) and miniature lens facilitate easy integration into space-constrained designs.
