Abstract
The utility model discloses an overheating alarm including at least one temperature sensor and at least one temperature transmitter. The number of the temperature transmitter is the same as that of the temperature sensor, and each temperature transmitter corresponds a temperature sensor. The overheating alarm also includes a single chip microcomputer, a sound and light alarm, an AD converter, a temperature controller, a battery and a buzzer. The temperature transmitter is connected to an input end of the single chip microcomputer through the AD converter. An output end of the single chip microcomputer is connected to the sound and light alarm. The temperature controller comprises a probe and two leads whose conduction is controlled by the probe. One lead is connected to a negative electrode of the battery negative through the buzzer, while the other lead is connected to a positive electrode of the battery. The overheating alarm is advantageous in that when a certain room temperature is reached, the temperature controller works and the two leads are conducted; the buzzer can be used for giving an alarm, and since the alarming process is independent of the single chip microcomputer system, double insurance can be formed with higher safety.
