As shown in the figure, it is a inductive automatic light with TWH9512 pyroelectric infrared sensor dedicated module, and it can be used for occasions such as bathroom, storage room, stairs aisle lights control, and it can realize that lights are lit when people come, and turned off when people leave. At the same time, it also has light control circuit, and it can automatically close circuit during the day, so the lights will not be lit.
