In order to realize the data collection of temperature, humidity and CO2 concentration in the greenhouse, an ultra-low power wireless sensor network system was designed to solve the problems of complex wiring and difficult maintenance of traditional monitoring systems. The working characteristics and power consumption of the microcontroller, sensor and wireless transceiver used in the wireless measurement node were analyzed, the structural principle of the wireless node was described, and the design scheme and communication method of the system software were given. The actual measurement results show that the designed system hardware structure is simple and reliable, the power consumption is small, and the communication distance is long, which meets the design requirements of greenhouse environmental parameter measurement.
