The AM312 human sensor module is a digital intelligent automatic control product that is based on passive body infrared technology, which is highly sensitive and to use. They are widely applied for all kinds of automatic induction electrical equipment. These human sensor modules are small in size, and feature low power 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 active within sensing range, output will keep high until the delay after the people leaves, then it will 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: less than or to 100 degrees cone angle, 3 - 5 m ( on the lens) Working temperature: -20 Celsius to +60 Celsius PCB size: . 10 x 8mm Model: Miniature human body sensor module PIR Power: 5W colour:Green Material:PCB size:25 x 12 x 12 mm Package Contents: 10 x PIR module Only the above package content, other are not included. Note: Light and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
