The module has an analog and digital output interface. The analog quantity can be sampled by the microcontroller A/D converter to know the current water contamination. The digital quantity can be adjusted by the potentiometer on the module. When the turbidity reaches the set threshold, the D1 indicator will be illuminated, the sensor module output will change from high level to low level, and the microcontroller will monitor the level change.
Determine whether the turbidity of the water exceeds the standard, thus alerting or linking other equipment. The module is low in price, convenient to use, high in measurement accuracy, and can be used for measuring the degree of water pollution of washing machines, dishwashers, etc.; it can also be used for industrial site control, environmental sewage collection and other occasions requiring turbidity detection and control.
