For Arduino Liquid Level Sensor Module Liquid Level Detection Water Level Monitoring Sensor Module

The liquid level sensor uses the principle of infrared optics to transmit the detected liquid level and liquid level signals through optical transmission and convert them into electrical signals for output. The liquid level is judged by the voltage signal collected by the sensor. The sensor is compact in design, small in size, waterproof, and has a cylindrical shape that is convenient for drilling and installation;
The installation methods are diversified, which can be installed on the top, bottom, sideways, and obliquely. The sensor head is smooth, easy to clean, and the accuracy is better than that of the float type liquid level switch. The controllable accuracy is within ±0.5MM.
The existing commonly used float type liquid level switch has an accuracy of ±3.0MM; light principle, no friction and other mechanical moving parts, the service life is greatly increased
