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 lowProduct : AM312Working voltage: DC 2.7V - 12VStatic consumption: less than 0.1mADelay time: 2 secondsBlocking time: 2 secondsTrigger mode: repeatableSensing range: less than or equal to 100 degrees cone angle, 3 - 5 m ( on the lens)Working temperature: -20 Celsius to +60 CelsiusPCB size: approx. 10 x 8mm: Miniature human body sensor module PIR: 5Wsize:25 x 12 x 12 mmMaterial: plasticcolour: greenPackage Contents:8 x Human Sensor ModuleOnly 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.
