Fully automatic induction: When someone enters its sensing range, it inputs a high level, and when the person leaves the sensing range, it automatically delays to turn off the high level. The output is low. Photosensitive control (optional): The module is reserved for position, and the photosensitive control can be set. It is not sensed during the day or when the light is strong. Photosensitive control is an optional feature and no photoresistor is installed at the factory. If necessary, please purchase separately With induction blocking time (default setting: 3-4 seconds): After each sensing output (high level goes low), the sensing module can be set to follow a blocking time, during which the sensor does not Receive any sensing signal This function can realize the interval between the sensing output time and the blocking time, and can be applied to the interval detection product. At the same time, this function can effectively suppress various interferences generated during the load switching process. Micropower consumption: quiescent current 65 microamps, especially suitable for dry battery powered electrical products.
