According to your power requirements, configure the corresponding AC contactor, and then use the human body induction switch to control the AC contactor, which can basically control any number of lights. At present, the human body pyroelectric induction switch turns on the light after detecting the moving person, and turns off the light after a delay. If the human body is detected again before turning off the lights, the lights will be turned off from the beginning. However, it has an innate defect, that is, it can only perceive the moving human body signal, and once a person is still, it can't perceive it.
