HALJIA High Quality Turbidity Sensor Detection Module Water Quality Test Washing Machine Housing Turbidity Transducer Compatible with Arduino

The turbidity module is a sensor module that measures impurities in water. It measures the light transmittance and scattering rate of suspended particulate matter in water by measuring the change in total suspended solids (TSS) in water, and uses light to detect suspended particulate matter. Liquid turbidity level increases as TTS increases. Turbidity is the measurement of particulate matter in water. It needs to be read by the MCU analog port. It needs turbidity calibration liquid to calibrate. It is not a multimeter to directly measure the voltage. The output voltage of each module is different. The module should be protected from light and the temperature of the light. The voltage will make the module output different voltage, 0-4.5 is only the reference voltage. Principle:Turbidity sensor 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 wavel
