Humidifiers have been seen everywhere in our lives. How can humidifiers detect water level changes? It is usually achieved by installing a liquid level detector. Today, we can use technology to show you the working principle of the photoelectric integrated liquid level sensor.

The integrated photoelectric liquid level sensor is divided into single-point type and multi-point type,

It has the following characteristics:

Small size, low power consumption; No mechanical movement, long service life; IP68 waterproof grade, high waterproof; Support personalized model customization.

How to apply photoelectric liquid level sensor to humidifier? Mainly through the built-in installation of photoelectric liquid level sensor, the photoelectric liquid level sensor is equipped with infrared emission tube and photosensitive receiver, and the detection part is a prism structure.

When there is no water, the light emitted by the transmitting tube will be refracted to the receiving tube after passing through the lens; So as to give a warning.

When there is water, the light refracts into the liquid, so that the receiver cannot receive or can only receive a small amount of light.

Shenzhen Nengdian Technology Co., Ltd. has been focusing on the development of sensor technology for 20 years, and has more than 50 patents in the fields of photoelectric technology and water level detection technology. The main products include photoelectric liquid level sensor, non-contact inductive sensor, ultrasonic liquid level controller, turbidity sensor, distance detection sensor, liquid flowmeter, photoelectric anti-tipping switch, etc.
