The working principle of turbidity sensor sensor: when the 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 penetrating the water sample decreases. The turbidity sensor measures the amount of light passing through to calculate the turbidity of washing water.

The water level sensor is one of the sensors. Its main function is to control the water level, ensure the water level of the washing machine in the working process and judge the water level.
