Wireless real-time greenhouse supervision and management system based on Zigbee technology

A wireless real-time greenhouse supervision and management system based on Zigbee technology is composed of a network control center of the upper layer and sensing nodes of the lower layer, wherein numerous wireless sensing nodes of the lower layer together form a treelike wireless sensing network; and the nodes mainly include a numerical control acquisition unit and a wireless communication unit. The numerical control acquisition unit is composed of a temperature-humidity sensor, a carbon dioxide concentration sensor, a light intensity sensor and a soil temperature-humidity sensor; a single chip and an ADC (Analog to Digital Converter) module are integrated inside the sensor so that direct output of a digital quantity can be realized; and the wireless communication unit employs CC2430 chip to realize high-performance transmission of data. The network control center of the upper layer realizes receiving, transmission and real-time display of data, and realizes remote control by means of GSM (Global System for Mobile Communications)/GPRS (General Packet Radio Service) networks. The wireless real-time greenhouse supervision and management system based on Zigbee technology is capable of helping farmers to observe the data information of the greenhouses in real time so that the farmer can manage the greenhouses more scientifically and conveniently; therefore, the wireless real-time greenhouse supervision and management system based on Zigbee technology has bright application prospect.
