About This 🌟AM312 Human Sensing Module: Based on passive body infrared technology digital intelligent automatic control products, high sensitivity, reliability, widely used in vari ous types of automatic induction electrical equipment. 🌟Low power consumption, small size, easy to install. 🌟Internal use of digital signal processing, pit interference strong. 🌟The output current is very low and can only be used for signalling purposes. If connected to an output device with excessive load, it will constantly fluctuate between high and low levels. 🌟Repeatable trigger mode: that is, after the induction output is high, in the delay period, if the body in its induction range of activities, the output will remain high until the delay after the person to become Low level. (Ie, the sensing module automatically detects a delay period after each activity of the human body, and takes the last active time as the starting point for the delay time). 🌟Working voltage: DC 2.7-12V;Static power consumption: Show more
