[Good function]Small in size, and feature low power consumption and nicely anti-interference, with internal digital signal processing and direct high and low level output. [High sensitivity] 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. [Repeat trigger]After high sensing output, during the delay time, human body is active within its sensing range;its output keep high until the delay after the people leaves, then it become low. [Excellent Quality] new and high quality Mini Pyroelectric PIR Human Sensor Module,widely applied for all kinds of automatic induction electrical equipment. [Standard sizes]Working voltage: DC 2.7-12V;Sensing range: less than or equal to 100 degree cone angle, 3-5 meters; (depending on the specific lens), Manufacturer: Mcnhbdgg
