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 turbidity sensor module converts the current signal output by the sensor into a voltage signal, and performs AD conversion data processing by the single chip microcomputer. The digital quantity can be adjusted by the potentiometer on the module. When the turbidity reaches the set threshold, the D1 indicator be illuminated, the sensor module output change from high level to low level, and the microcontroller monitor the level change. Determine whether the turbidity of the water exceeds the standard, thus alerting or linking other equipment., Weight: 0.03858089585 pounds, Manufacturer: Wesafrae
