Self-cleaning turbidity sensor

Strong resistance to external light interferenceAutomatic temperature compensation
A digital turbidity sensor for water quality monitoring with automatic cleaning;
Adopt the foreign mature 90° scattered light principle, and use the design method of infrared LED light source and optical fiber transmission light path;
The filter design is added inside, and the ability to resist external light interference is strong.
The built-in temperature sensor can automatically compensate the temperature, which is suitable for online long-term monitoring environment.
