The utility model discloses a device capable of preventing cooling liquid in an engine from boiling based on a singlechip. The device comprises a temperature sensor installed in an engine cooling water sleeve. The temperature sensor is connected with an amplifier. An electrical signal of the amplifier is connected with the singlechip through an analog/ digital (A/D) converter. The singlechip is connected with a loudspeaker through an alarming circuit. The device has the advantages of being good in practicality, convenient to manufacture, simple in circuit, low in cost and the like. Cooling liquid temperature in an engine can be detected in real time, when the temperature is over high and reaches a set temperature, an alertor whistles, and a driver shuts down the engine. The occurrence of accidents is effectively prevented, and use safety of the engine is improved.
