More Information
Summary:A microwave oven has only a microwave sensor or both microwave sensor and temperature sensor. The microwave sensor has a wave absorber to generate heat through absorption of microwave energy and a thermistor to detect temperature of this wave absorber. The temperature sensor has a thermistor to detect the ambient temperature around the wave absorber. A controller determines a value of microwave power on the basis of the output of the microwave sensor or each output of the microwave sensor and temperature sensor. The microwave oven can accurately detect microwave power without being influenced by variation of ambient temperature around the microwave sensor.
