Environment monitoring and early warning system of facility agriculture based on heterogeneous wireless networks

This paper presents a distributed heterogeneous wireless sensor network for facility agriculture environmental monitoring and early warning system based on Internet of Things technologies, namely using the ZigBee wireless sensor network technology in real-time monitoring of facility agriculture environmental parameters, such as temperature and humidity. In exceptional case, GSM SMS will notify the user to take appropriate environmental regulation measures. The system includes a ZigBee coordinator node, multiple ZigBee sensor nodes, multiple ZigBee routing nodes, a GSM SMS module, and the management software based on SQL running on the remote control center PC. The real-time collection and early warning from facility agriculture environmental parameters enhance the level of facility agricultural management, thus improving the yield of the crop.
