Description: This electrical floor-warming controller aims at measuring, controlling and ouputing temperature. The said controller including: relay module, buzzer module, nixie tube module, single-chip module，reset circuit, independent key module and temperature sensor module. The working procedure of the controller will be showed as: the single-chip microcomputer controls voltage and temperature of heating cable via relay module two sensor measure temperature of heating cable and the room seperately, the key module determing sending whether the signal of one of the sensors or determined temperature to the nixie tube module the single-chip microcomputer compares the temperature of sensor and alarming temperature, if the temperature of the sensor is higher, the buzzer module will be set up to alarm.
