Remote monitoring alarm system for air quality

A remote monitoring system for air quality relates to the technical field of a signal processing technique, an embedded system and an alarm technique. For settling a problem of incapability of performing integrated management and monitoring on equipment and data currently, the utility model provides the remote monitoring alarm system. An air quality sensor is used for directly collecting harmful gas component in the air. The signal output end of the air quality sensor is connected with the signal input end of a signal conditioning circuit. A conditioned signal output end of the signal conditioning circuit is connected with an analog signal input end of an AD converter. The digital signal output end of the AD converter is connected with the signal input end of the embedded system. The signal input end of an alarm is connected with an alarm signal output end of an ARM microprocessor. The signal output end of the ARM microprocessor is connected with a signal input end of an upper computer through an RS485 communication interface. The remote monitoring system for air quality is suitable for performing remote monitoring on the air quality and alarming.
