HC-SR505 PIR Mini sensing module

Product description:

HC-SR505 small body sensing module is based on infrared technology, automatic control products, high sensitivity, reliability, ultra-small size, low voltage operation mode. Widely used in various auto-sensing electrical equipment, especially battery-powered automatic control products.

Features:

Automatic induction: to enter its sensing range, the output high, people left the sensing range is automatically delay off high, output low.Ultra-small size.Repeatable trigger: the sensor output high, the delay period, if there is human activity in its sensing range, the output will remain high until the people left after the delay will be high goes low (it will be automatically extended after sensing module detects the human body every activity a delay period of time, and with the last activity time as the starting point of the delay time).Wide operating voltage range: the default working voltage DC4.5V-20V.Micropower: quiescent current of <50 microamps, especially for battery-powered automatic control products.Output high level signal: easy docking with the various types of circuit realization.

Applications:

Human body induction lamp induction Toys industrial automation and control security products auto-sensing electrical equipment  Battery-powered automatic control
