The AM312 human sensor module is a digital intelligent automatic control product based on passive body infrared technology, sensitive and reliable to use. Widely applied for various automatic induction electrical equipment. These modules are small in size, with low power consumption and good anti-interference, featuring internal digital signal processing and direct high and low level output. After high sensing output, during the delay time, if a human body is active within its sensing range, the output will keep high until the delay after leaving, then become low. Product model: AM312; Working voltage: DC 2.7V - 12V; Static power consumption: less than 0.1mA; Delay time: 2 seconds; Blocking time: 2 seconds; Trigger mode: repeatable. Sensing range: ≤100 degrees cone angle, 3-5m (depend on specific lens); Working temperature: -20℃ to +60℃. PCB size: approx. 10x8mm; Material: PCB; Size: 25x12x12mm; Color: as shown. Package Contents: 10 x PIR module. Only the above package content, other products not included. Note: Light shooting and different displays may cause color difference; measurement error allowed +/-1-3cm.
