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 reliable 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 its sensing range, its output will keep high until the delay after the people leaves, then it will become lowProduct model: AM312Working voltage: DC 2.7V - 12VStatic power 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 (depend on the specific lens)Working temperature: -20 Celsius to +60 CelsiusPCB size: approx. 10 x 8mmModel: Miniature human body sensor module PIRPower: 5Wcolour:GreenMaterial:PCBsize:25 x 12 x 12 mmPackage Contents:10 x PIR moduleOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
