This paper describes an on-line monitor system based on wireless sensor networks, which could test the ingredients of vehicles' off-gases, and also introduces the design of the hardware and software in details, and transplants the Zigbee protocol on the system at last. With the character of portability and the high precision gas sensors, the system could monitor the off-gases and distinguish the ingredients...
Aiming at the requirement of real-time monitoring of looms and limitations of subsistent monitor systems, a new monitor system based on ZigBee technology for looms was proposed, and then put forward its network structure. The CC2430 chip based on ZigBee technology from TI Company was applied to node controllers which function as data collection and transmission, management of monitoring network, fault...
This paper presents a design of wireless monitoring system based on Zigbee for temperature and humidity. The system consists of terminal nodes, central node and personal computer. Compared with the traditional methods, this system can work continuously in the monitored area because of its lower power and low complexity characteristics in the hardware design. Test result indicates the system can be...
According to the characteristics of coal mine environment, in this paper we propose a multi-parameter wireless sensor network monitoring system based on Zigbee technology for coal mine tunnel. The system can real-time monitor the underground environment and production parameters and intelligently give early warning by using a variety of sensors and wireless sensor network. It is flexible to add sensors...
