TS-300B Turbidity Sensor Detection Module Water Quality Test Washing Machine Turbidity Transducer for Arduino
Get TS-300B Turbidity Sensor Detection Module Water Quality Test Washing Machine Turbidity Transducer for Arduino Principle: Turbidity sensor TS-300B measures the turbidity (counter of suspended matter) in the wash water. Based on the optical principle, the sensor uses the light-emitting diode and phototransistor to receive the specific wavelength to measure the opacity or other substances of dirty water. concentration. By using phototransistors and light-emitting diodes, the light emitted by the sensor through the light-emitting diode source is reflected by the sewage, part of the light is transmitted to the phototransistor, and the turbidity of the water is calculated according to the amount of light received. Features: 1. The working principle the turbidity sensor: When light passes through a certain amount of water, the amount of light penetration depends on the amount of dirt in the water. When the amount of dirt increases, the
