Generally, there are two types of sensing elements:
1. Light sensing and voice activated induction;
2. Light sensing: infrared induction.

Now there are three more practical light control sensing devices on the market: voice control induction, light sensing, infrared human body induction, etc.
The toilet infrared sensor is realized by connecting the solenoid valve through the infrared sensor switch. >>>More
I'm under the bathroom basin hanging cabinet, and the sensor light is always on, so I should check if the contact is not good? Always plugged in the power.
If you use it, it is like destroying an ordinary light bulb. >>>More
Yes. In my house, there are not only bathrooms, but also living rooms, bedrooms, and other rooms. It's just that this kind of induction switch is added by myself with a pyroelectric infrared induction switch, which can sense the stationary human body, and the delay shutdown time is set to about 10 seconds. >>>More
People come and the lights come on. People walk away and the lights go out. It is designed with infrared sensors, ICs, and lenses. For details, you can consult Liqian Industry.
