PIR MODULE HC-SR505 Human motion Module Sensor

product description: HC-SR505 small body sensor module is based on infrared technology, automatic control products , high sensitivity, reliability, ultra-small size, ultra-low voltage operation mode. Widely used in various auto-sensing electrical equipment , especially battery-powered automatic control products. Product Features: Automatic induction: to enter its sensing range, the output high, people left the sensing range is automatically shut down delay high and low output. ultra-small size. Repeatable trigger mode: that is, after sensing the output high, in the delay time period, if the human body in its sensing range of activities, its output will remain high until the people left after the delay will be high (Sensing module automatically detects a delay in the human body after a delay time period, and the time of the last activity for the delay time of the starting point). Operating voltage range: the default operating voltage DC4.5V-20V. micro-power: quiescent current 50 microamps, especially for dry battery-powered automatic control products. outputs a high level signal: easy docking with the realization of various types of circuits. Applications: human induction lighting human induction toys security products industrial automation and control auto-sensing electrical equipment Battery-powered automatic control , etc.
