Abstract: This paper takes the agricultural production process monitoring equipment system as the research object, designs a wireless monitoring equipment system for agricultural production process based on polarization antenna and GPRS. The paper uses temperature and humidity sensor, light intensity sensor and soil salt sensor to collect agricultural environmental parameters, and sends sensor data to the application layer of the system by wireless communication network, analyzes and processes data, generates relevant control instructions, and drives the actuator structure to adjust environmental parameters.The experimental data show that the wireless monitoring equipment system designed in this paper has high data monitoring accuracy in the process of operation, and can meet the needs of agricultural production process.
