Moisture Sensor
A moisture sensor is a device used in appliances like washing machines, dryers, and dishwashers to detect water levels and moisture content. It helps appliances work more efficiently by automatically adjusting water usage and drying times. Think of it as a device that acts like a digital finger testing if something is wet or dry. Technicians who work with these sensors need to know how to test them, replace them when they fail, and make sure they're properly calibrated so the appliance works correctly.
