The AM312 human sensor module is a digital intelligent automatic control product based on passive infrared (PIR) technology, offering high sensitivity and reliability. It is widely used in various automatic induction electrical devices. This module features a compact size, low power consumption, and strong anti-interference capability. It includes internal digital signal processing and provides direct high/low level output. After detection, the output remains high during the delay period; if motion is detected within the sensing range during this time, the output stays high until motion ceases and the delay expires. Product model: AM312 Working voltage: DC 2.7V – 12V Static power consumption: < 0.1 mA Delay time: 2 seconds Blocking time: 2 seconds Trigger mode: Repeatable Sensing angle: ≤ 100° cone Sensing distance: 3–5 m (depending on lens used) Operating temperature: –20°C to +60°C PCB size: Approx. 10 × 8 mm Module type: Miniature PIR human body sensor Power rating: 5 W Color: Green Material: PCB Dimensions: 25 × 12 × 12 mm Package contents: 10 × AM312 PIR sensor modules Note: Color appearance may vary slightly due to lighting conditions and display settings. Dimensional tolerance: ±1–3 cm.
