TS-300B | High Quality Arduino Turbidity Sensor
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.
