Turbidity Sensor With Module for Liquid Particle Detection A turbidity liquid particle detection sensor is a device that is used to measure the turbidity, or cloudiness, of a liquid. Turbidity is often used as an indication of the presence of suspended particles in the liquid, such as dirt, algae, or bacteria. The sensor works by shining a light through the liquid and measuring the amount of light that is scattered or absorbed by the particle detection. 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. It is not the multimeter that directly measures the voltage. The output voltage of each module is different. The module should be protected from light and light. The temperature and voltage will make the output voltage of the module different.  These decisions are made on the basis of a comparison between clean water measurements (taken at the beginning of the wash cycle) and the wash water turbidity measurement taken at the end of each wash cycle. By measuring the turbidity of the wash water, the dishwasher can conserve energy on lightly soiled loads by only washing as long as necessary. This will result in energy savings for the consumer. Parameters of the Turbidity Particle Sensor: Voltage: 3.3-5V (with anti-reverse circuit) Output: default analog (can set high and low output) Measuring range: 0-1000 NTU Key

The motor's speed can be changed as a result of this. The hall effect sensor calculates this change and outputs it as a pulse signal. The rate of flow of water can thus be measured. The Hall effect is the primary operating principle of this sensor. The rotation of the rotor induces a voltage difference in the conductor in this sensor, according to this principle. This induced voltage difference runs in the opposite direction of the electric current. When the moving fan rotates due to the flow of water, the rotor rotates, inducing a voltage. The hall effect sensor measures the induced voltage and displays it on the LCD display. read more : What is a Water Sensor?
