Product Function: The temperature sensor in a washing machine is usually used to sense changes in the temperature of the wash water. It measures and transmits information about the temperature inside the washing machine. During the washing process, the user can select different water temperatures, such as cold, warm or hot water. The temperature sensor will send the measured temperature information back to the control board according to the user's choice, and the control board will then use this information to adjust the operating status of the heater or other equipment to achieve the water temperature chosen by the user.
