Agricultural Environment Monitoring System Real-time Monitoring of Multiple Soil Parameters in Farmland

Agricultural Environment Monitoring System is a farmland meteorological observation device integrating multiple sensors. It can monitor parameters such as temperature, humidity, wind speed, wind direction, rainfall, sunlight, radiation, carbon dioxide, and soil temperature, humidity, conductivity, pH value, nitrogen, phosphorus, potassium, and evaporation. The device consists of five parts: sensors, a data logger, a solar power system, a pole support, and a cloud platform. It is suitable for agriculture, forestry, meteorology, and other fields.

Agricultural Environment Monitoring System is a highly integrated, low-power, quick-installation, and easy-to-use high-precision meteorological observation device for field monitoring. It consists of five parts: meteorological sensors, a data logger, a solar power system, a pole support, and a cloud platform. It requires no debugging, can be quickly deployed, and is widely used in meteorology, agriculture, forestry, scientific research, and other fields.

Regarding monitoring parameters, Agricultural Environment Monitoring System can monitor meteorological elements in real time, including air temperature, air humidity, atmospheric pressure, precipitation, wind speed, wind direction, light intensity, ultraviolet radiation, sunshine duration, and carbon dioxide concentration. It can also measure soil parameters such as soil temperature, soil moisture, soil conductivity, soil pH, soil nitrogen, phosphorus, and potassium content, and soil evaporation. In terms of sensor accuracy, the air temperature measurement range is -40 to 80℃ with an accuracy of ±0.3℃; air humidity is 0 to 100%RH with an accuracy of ±3%RH; wind speed is 0 to 30 m/s; and rainfall measurement accuracy is ±0.2 mm. The soil temperature measurement range is -40 to 80℃ with an accuracy of ±0.5℃; soil moisture is 0 to 100% with an accuracy of ±3%; and soil conductivity is 0 to 20000 μS/cm.

Data acquisition and transmission are the core functions of this device. The data acquisition unit has a static power consumption of less than 1 mA, supports GPRS networking, and can be equipped with Bluetooth or wired transmission methods. The device features a 7-inch Android touchscreen and supports Modbus 485 sensor expansion. Data upload intervals are adjustable from 1 minute to 1000 minutes. The solar power system is equipped with an MPPT automatic power point tracking charger and can be equipped with lead-acid batteries of different capacities, improving efficiency by up to 20%. The data logger's power interface is a GX-12-3P plug, with an input voltage of 5V and an output JSON data format.

The cloud platform serves as the data management and analysis terminal for Agricultural Environment Monitoring System. The platform adopts a client-server architecture and supports direct access via mobile phones and PC browsers without requiring additional software installation. Users can remotely view real-time data, historical data, and trend charts through the cloud platform. The device supports SMS alarm functionality, sending alarm messages to designated mobile phones when monitored data exceeds limits. Agricultural Environment Monitoring System combines IoT technology and big data analytics to provide decision-making support for irrigation and fertilization systems based on weather conditions and crop growth, facilitating intelligent farmland management.
