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.

* A0 pin of sensor is connected to Arduino analog input pin : Analog output voltage 0~4.5V [ Analog output mode ] **D0 pin of sensor is connected to Arduino Digital input pin : Digital output High or Low [ Digital output mode ] An Arduino code is available to test the module in both cases.
The above schematic of the turbidity sensor is applicable to Arduino Uno connection. In the same way, you can connect this TS-300B module to other Arduino board such as Arduino Mega and Arduino Nano.

Select a specific turbidity contrast solution and adjust the potentiometer knob to the position where the D1 indicator light is just lit (ie, the threshold of high and low levels) to complete the threshold setting. The DO port of the sensor module is connected to the I/O port of the MCU for output signal judgment or connected to an external drive circuit to drive other devices.
This is a super cool water quality sensor module that enable you to monitor the turbudity of any liquid using Arduino, without spending too much budget..
