- The design is based STC89C52 single-chip, using MQ-4 ammonia sensor and MQ-7 carbon monoxide sensor, while testing the ammonia and carbon monoxide, when the discovery of the detected gas concentration exceeds a certain concentration, the sensor voltage has changed. Through the LM393 comparator issue the corresponding signal to the single-chip STC89C52. Then single-chip received signal control stepper motor action, at the same time controlling the buzzer to alarm, reached early warning purposes.
