Product Specification

TS-300B is a High Quality Turbidity Sensor with analog and digital interface for Arduino. This is the low cost Arduino Turbidity Sensor DIY Projects.

The turbidity of water refers to the degree of turbidity caused by suspended matter such as sediment, clay, organic matter, plankton and microorganisms contained in water. Industrial grade turbidity sensors or turbidimeters are expensive and not costly in electronics design; therefore, we have chosen a turbidity sensor that is widely used in household appliances washing machines and dishwashers.

Turbidity Sensor working Principle

The sensor uses the optical principle to comprehensively determine the turbidity by the transmittance and scattering rate in the solution. Inside the sensor is an infrared pair tube. When light passes through a certain amount of water, the amount of light transmitted depends on the degree of contamination of the water. The dirtier the water, the less light is transmitted. The light receiving end converts the transmitted light intensity into a corresponding current magnitude, and the transmitted light is large, and the current is large, and the transmitted light is small, and the current is small.

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.

Function

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.
