Mini Human body sensor module HC-SR505 Infrared ray Body sensor switch
 
Description:
HC-SR505 human body sensing module is an automatic control product based on infrared technology, with high sensitivity, strong reliability, small size, and low voltage working mode. It is widely used in various automatic induction electrical equipment, especially automatic control products powered by dry batteries.

Features:
●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.
●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 sensing 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.

Application:
● Human body induction lamps
● Human body induction toys
● Security products
● Industrial automation control
● Automatic induction electrical equipment
● Battery powered automatic control, etc.
