| Zusammenfassung: | The invention relates to a temperature-sensing alarm circuit, the circuit comprises a temperature-sensing glass ball, an SOC circuit and an alarm, a first end of the temperature-sensing glass ball is connected with power supply voltage through an input resistor, and a second end of the temperature-sensing glass ball is connected with a grounding end. The SOC circuit is connected with the first end of the temperature sensing glass ball and used for detecting the voltage value of the first end of the temperature sensing glass ball. When the environment temperature does not reach the explosion temperature of the temperature-sensing glass ball, the temperature-sensing glass ball does not explode, a circuit between the power supply voltage and the temperature-sensing glass ball is switched on, and the voltage of the first end is low level. When the environment temperature reaches the explosion temperature of the temperature sensing glass ball, the temperature sensing glass ball is exploded, the circuit between the |
