The AM312 human sensor module is a digital intelligent automatic control product is based on passive body infrared technology, which is highly sensitive and reliable to . They are widely applied for all kinds of automatic induction electrical equipment. These human sensor modules are small in size, and feature low consumption and nicely anti-interference, with internal digital signal processing and direct high and low level output. After high sensing output, during the delay time, if a human body is within sensing range, output will keep high until the delay after the people leaves, then it will become low Product : AM312 Working voltage: DC 2.7V - 12V Static consumption: less than 0.1mA Delay time: 2 seconds Blocking time: 2 seconds Trigger mode: repeatable Sensing range: less than or equal to 100 degrees cone angle, 3 - 5 m ( on the lens) Working temperature: -20 Celsius to +60 Celsius PCB size: approx. 10 x 8mm : Miniature human body sensor module PIR : 5W colour:Green Material:PCB size:25 x 12 x 12 mm Package Contents: 10 x PIR module Only the above package content, other products are not included. Note: Light and different displays may the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
