Mini PIR Infrared Motion Sensor Detector Module
This is an pir infrared movement sensor module , commonly used to detect human body movement. It has higher sensitivity and broader detective range than others. Once a person enters into the detective range, the output will be high level. While the person goes out of the detective range, it will prolong automatically 20 seconds of retention time then the high level output will shift to the low level output. This device requires a 5-9V signal to operate. Typical applications are for automatically controlling lights, and taking snapshots of pests or wild animals. Widely applied for movement detection, automatic control, proximity switch, electronic theft prevention, safety protection, remote control measurement, etc. Features: Repeated triggering method Broad working voltage, low power consumption High level signal output, easy to be butt jointed with different types of circuits Retention time is adjustable Working voltage is adjustable Specification: Operating temper...
