DollaTek 3.3-5V Turbidity Transducer Water Turbidity Module Mixed Water Detection Module for Arduino

• Turbidity is the measurement of particulate matter in water. It requires the analog port of the MCU to read the analog value for calculation. It needs turbidity calibration liquid to calibrate.
• 98% of the genuine industrial alcohol is ONTU, 1000NTU everyone can When you buy it separately, you must remember that the light temperature and voltage will be affected. The light interference can be placed in the dark box to avoid the use of light.
• The voltage needs you to provide a stable voltage and current. The temperature requires a temperature sensor and the temperature is compensated.
• Do not completely immerse the sensor in water. Just measure the small round head of the split fork into the water and measure it. Do not wipe the top of the head.
• The sensor is realized by the refractive index of the light, so the light will also interfere with the sensor, and should be kept away from light interference when using.

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 light that penetrates the water sample decreases, and the turbidity sensor measures the amount of light transmitted to calculate the turbidity of the wash water. 2. The turbidity sensor provides these turbidity measurements to a washing machine or dishwasher controller, with the washing machine and dishwasher controller determining the time of each wash cycle. These judgments are based on a comparison between the measured value of the purified water (measured at the beginning of the washing cycle) and the measured value of the washed water measured at the end of the washing. 3. By measuring the turbidity of the wash water, the washing machine can only wash the time required when washing clothes that are not very dirty, thereby saving energy, so that the end user saves energy.
