Product Overview:
HC-SR505 small human body sensor module is an automatic control product based on infrared technology, high sensitivity, high reliability, small size, low voltage working mode. Widely used in all kinds of automatic sensor electrical equipment, especially dry battery-powered automatic control products.
Product features:
■ Full-automatic sensing: high level output when a person enters its sensing range, and low level output when a person leaves the sensing range with automatic time-delayed switching off of the high level.
■ Small size.
■ Repeatable trigger mode: that is, after the sensor output high level, in the delay time period, if there is a human body in its sensing range of activities, its output will be kept high until the person leaves the delay will be high level to low level (the sensor module detects the human body's every activity will be automatically postponed for a delay time period, and the time of the last activity as the starting point of the delay time).
■ Wide operating voltage range: default operating voltage DC4.5V-20V.
■ Micro power consumption: quiescent current <50 microamps, especially suitable for dry battery powered automatic control products.
■ Output high level signal: it can be easily interfaced with all kinds of circuits.
Application range:
■ Human body sensor lamps ■ Human body sensor toys
■ Security products ■ Industrial automation control
■ Automatic sensor electrical equipment ■ Battery-powered automatic control, etc.
