Based on ZigBee wireless sensor network the monitoring system design for chemical production process toxic and harmful gas

Aiming at monitoring information of HCHO, CH4, LPG and other toxic and harmful gas concentrations in the chemical production plant, the monitoring system designed a ZigBee wireless sensor network composed of CC2430, MC114 and MS1100 gas sensor, which built a safe, low power consumption, flexible detection system of toxic and harmful gas concentrations. As the system data transmission with the mode of sensor test data in a short distance, multi-node, self-organizing wireless network, it could use the USB interface gateway to connect the WSN and internet to implement the data transmission with internet.
