HC-SR505 small human body sensing module is an automatic control product based on infrared technology , with high sensitivity, strong reliability, ultra-small size, and ultra-low voltage working mode. It is widely used in various automatic induction electrical equipment , especially automatic control products powered by dry batteries.
■ Automatic induction: when a person enters its sensing range, it outputs a high level, and when a person leaves the sensing range, it automatically delays the shutdown of high level and outputs a low level.
■ Ultra small size.
■ Repeatable trigger mode: After the sensor outputs a high level, during the delay time, if a human body is active in its sensing range, its output will remain high until the person leaves. Change to low level (the sensor module will automatically extend a delay time period after detecting each activity of the human body, and take the time of the last activity as the starting point of the delay time).
■ Wide operating voltage range: The default operating voltage is DC4.5V-20V.
■ Micro power consumption: quiescent current <50 microamperes, especially suitable for automatic control products powered by dry batteries.
■ Output high-level signal: It can be easily connected with various circuits.
■ Human body induction lamps ■ Human body induction toys
■ Security products ■ Industrial automation control
■ Automatic induction electrical equipment ■ Battery powered automatic control, etc.
