摘 要: 鉴于单片机STC89C52具有高集成度等优点,开发设计了一种基于STC89C52的一氧化碳报警器,为了提高系统的灵敏度和准确性,系统采用了电化学传感器。该报警器对一氧化碳(CO)进行实时监控,当一氧化碳的浓度超过允许值时,控制电路进行报警,并通过外接排风扇与电磁阀对其进行程控,以防事故的发生。 Carbon monoxide alarm is designed based on STC89C52 with a high level of integration. In order to improve sensitivity and accuracy, the electrochemical sensor is used. The carbon monoxide alarm is monitored on for real - time,when permitted value of the concentration of carbon monoxide is exceeded, the control circuit will alarm, and it is programcontrolled through external row fans and solenoid valve with for preventing accidents.
