Abstract:

In order to reduce the loss caused by the gas leak and enhance the safety monitoring of using gas, a gas monitoring system based on wireless sensor networks is designed. The system is mainly composed of gas wireless monitoring nodes and mobile monitoring terminal. In the system, the wireless monitoring nodes based on the Tiny OS 2.0 platform use the nesC language to design the sensor program ,their key components are low power micro-processing unit ATmega1281,2.4GHz RF chip AT86RF230 and gas sensor MQ-2. Also, the ARM processor S5PV210 is used to design a mobile monitoring terminal with the Android 4.2 platform. The terminal can realize the functions such as real-time alarm, mobile monitor and dynamic display. Experiment results show that the system has the features such as simple deploy, high measurement precision and low power consumption, false alarm rate does not exceed 0.5% and can sustainable work 180 days.
