Design for Double Security of Thermal Energy Transmission

This paper mainly uses the microcontroller STC89C52 to receive the temperature sensor and water level sensor sent by the A/D module after conversion of the data and processing through the dual-optical circuit relay on the power switch operation, the first heavy protection for temperature protection, that is, the water temperature reaches boiling, automatic power failure; the second heavy for the water level protection, mainly to prevent dry burning. To a large extent, it can avoid the occurrence of safety accidents caused by the heat fast dry burning, but also can save power.
