Crop growth information acquisition system based on ZigBee

The invention discloses a ZigBee-based crop growth information acquisition system, which comprises a ZigBee node module, an RS485 interface module, a network server and a power supply module for providing electric energy, wherein an acquisition terminal node is in communication connection with a coordinator node through a wireless communication module; the crop growth state data acquired by the data detection sensor is transmitted to the coordinator node based on the equipment judgment strategy; the coordinator node performs Base64 coding on the received data to obtain coded character string data, and the wireless terminal equipment node DTU transmits the cached coded character string data to the network server based on a data transmission strategy to realize storage of crop growth state data. The problems that in the crop growth process, due to the fact that existing monitoring equipment cannot comprehensively monitor environment data due to the too large data collection area, the position deployment of an e
