In China's modern intelligent agricultural facilities greenhouse has been widely used. Whether the environment is suitable for the growth and development of crops is very important, which directly determines whether the high yield and harvest can be achieved. In order to ensure that the crops can be in the most suitable growth environment in the greenhouse, the environmental parameters in the shed must be accurately monitored. Aiming at the problems of high cost and complicated wiring, a design scheme of indoor environment monitoring system based on close-range wireless network communication technology is proposed. This scheme selects the SHT21、TSL2561、CCS811 to detect the environmental parameters such as temperature and humidity, light intensity and carbon dioxide gas concentration in the shed. The CC2530 microprocessor is used to collect the environmental parameters of the sensor in real time, and the data is transmitted and uploaded wirelessly through the ZigBee module to realize the host PC monitoring. The temperature error of the system does not exceed ±0.3℃ in the actual test, the humidity error does not exceed ±2% RH, the packet loss rate of the network data in the range of use distance does not exceed 2%, the system runs stably and has strong reliability, which can meet the design requirements.
