Abstract On the Main Board of the anesthesia ventilator fan, as long as the energized permanent work easily damaged. The design temperature measurement and control system to improve the shortcomings. So that the fan can be adjusted automatically according to the temperature level of the working state. When the temperature is too high, the fan works, and vice versa stall. The subject using a temperature sensor to measure the current temperature; fan rotation when the temperature exceeds 30 ° C; fan stopped working when the temperature is below 30 ° C; give an alarm when the temperature exceeds 45 ° C, when the temperature is below 45 ° C, alarm signal disappears; digital display temperature measurements, the final design of the hardware and software of the system.
