Principle and application of water turbidity sensor

Working principle of water turbidity sensor:

Turbidity is caused by suspended particles in the water. Suspended particles will diffusely reflect the incident light, and the scattered light in the direction of 90 degrees is usually used as the test signal. The scattered light and turbidity conform to a multi-segment linear relationship. Therefore, the sensor needs to be calibrated at multiple points. Moreover, the intensity of the light source and temperature changes will affect the accuracy of the measurement results. After many experimental studies and theoretical calculations, it is found that the ratio of scattered light to transmitted light is in a linear relationship with turbidity.

The water quality turbidity meter uses the ratio of scattered light to transmitted light instead of pure scattered light to measure turbidity. The accuracy and reliability of the sensor are improved, the maintenance is simpler, and the stain resistance is enhanced.

Water quality turbidity sensor application:

Today, fully automatic washing machines have entered thousands of households. Its functions are getting more and more, and the tricks are constantly being renovated. The parameters for judging the performance of washing machines are no longer the most basic indicators such as washing ratio. Energy consumption and water consumption. Usually, the user sets the washing time and the number of rinsing times of the washing machine based on experience. To allow the washing machine to process automatically it will usually give priority to meeting the requirements of the washing ratio. However, less consideration is given to energy consumption and water consumption, resulting in a waste of water and electricity.

A turbidity sensor is used to measure the dirtiness of clothes. It is a more feasible method by judging the degree of pollution. Determine the best washing time and rinsing times, you can use less energy and water consumption to obtain a cleaning ratio that meets the requirements.

The turbidity sensor is a low-cost sensor specially used for home appliances. It is mainly used to measure the degree of water pollution of washing machines, dishwashers and other products. By measuring the degree of water pollution to determine the cleanliness of the washed items, so as to determine the best cleaning time.
