Considering the current situation that the temperature control systems in market have the general disadvantages of complicated structure, high power consumption and tremendous cost, a new greenhouse temperature supervising system is designed, with a Arduino Mega 2560 single chip microcomputer as the core, XBEE as the short distance wireless transferring tools, and with function of displaying information in computers and remote control. The core component of this system is the Arduino software-hardware open source platform, which is currently popular in the market. This platform embraces the excellence of stability, low power consumption, cheap cost and easy operation as its advantages and selling points. XBEE can constitute the mesh network, each module of which can supplied as the route node, coordinator and terminal node. This system can achieve the functions of collecting data from sensors while is capable of displaying these data in the computers and put them under the network remote control. Easy to install, it can simultaneously achieve network monitoring several greenhouses. Enormous convenience to production inside the greenhouse is fulfilled due to these mentioned features as well, which makes it suitable to the small scale agricultural production.
Monitoring system design of mine gas Monitoring System were designed according to the traditional lacked of the real-time and early warning functions and so on problems. A multi-hop sensor network based on TinyOS is designed. The system is based on hierarchical network architecture. The software design principle based on TinyOS is introduced, which can realize the multi-hop communication. A simple Ant colony algorithm is designed in this sensor network to improve the network lifetime. According to simulation results and Test Research, this system can efficiently realize the multi-hop data communication and reliable.
