Features:

1. Fully automatic induction: When someone enters its sensing range, input high level, and when someone leaves the sensing range, it will automatically delay and turn off high level. Output low level.
2. Photosensitive control (optional): The module has a reserved position, which can be set for photosensitive control, and does not sense during the day or when the light is strong. The photosensitive control is an optional function, and no photosensitive resistance is installed at the factory. If necessary, please purchase separately 3. Two trigger modes: L can not be repeated, H can be repeated. It can be selected by jumper, the default is H. You can buy 5506 photoresistors in our store to cooperate with.
    A. Non-repeatable trigger mode: After sensing the output high level, once the delay time is over, the output will automatically change from high level to low level.
    B. Repeatable trigger mode: After the sensor outputs a high level, during the delay period, if a human body moves within its sensing range, its output will always remain high, and the delay will be high until the person leaves. The level changes to a low level (the sensing module will automatically extend a delay time period after detecting each activity of the human body, and the time of the last activity is the starting point of the delay time).
4. With induction blocking time (default setting: 3-4 seconds): after each induction output (high level to low level), the induction module can set a blocking time immediately, and sense in this time period The device does not receive any induction signal. This function can realize the interval work (induction output time and block time), and can be applied to interval detection products; at the same time, this function can effectively suppress various interferences generated during load switching.
5. Wide operating voltage range: the default operating voltage is DC5V to 20V
6. Micro power consumption: 65 microamps quiescent current, especially suitable for electrical products powered by dry batteries.
7. Output high-level signal: it can be easily connected with various circuits.
