TURBIDITY WATER SENSOR

The working principle of the turbidity sensor sensor: When light passes through a certain amount of water, the amount of light penetration depends on the amount of dirt in the water. As 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.

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.

By measuring the turbidity of the wash water, the washing machine can only wash the time required to wash the laundry which is not very dirty, thereby saving energy, so that the end user saves energy.

• Turbidity is the measurement of particulate matter in water.
• Read by MCU analog port for calculation.
• Needs turbidity calibration liquid to calibrate.
• Cant measure voltage directly with multimeter.
• Output voltage of each module is different.
• The module should be protected from light and the temperature.
• The voltage will make the module output different voltage, 0-4.5 is only the reference voltage.
• Output: default analog (can set high and low output)
• Measuring range: 0-1000 NTU
