The Ammonia Leak Monitoring and Warning System Based on Wireless Sensor Network in Industrial Environments

摘要

In order to prevent the ammonia leak caused casualties incidents, this paper adopts ZigBee wireless technology to real-time monitoring of ammonia concentration. Equipped with MQ137 ammonia sensor in the terminal node, and the use of STM8 microcontroller collected the ammonia concentration data. The data will be transmitted to the coordinator through ZigBee. Using LabVIEW to design the monitoring interface of computer, and read concentration data through the serial port communication. When the ammonia concentration exceeds the preset value, the GSM module will send the location of leak in the form of short messages to staff. Through the reasonable arrangement of sensor nodes in ammonia production workshop, can effectively avoid the ammonia leak hurting the safety of people's life and property.
