Agricultural monitoring

MEI smart weather monitoring system is the solution IoT uses STM32, connect 4G LTE and solar energy to monitor environmental parameters in real time. The device supports sensor connection RS485 Modbus RTU or 4–20 mA such as wind speed, wind direction, rainfall, light intensity, temperature and humidity. Data is transmitted to the platform MEI ECO via protocol MQTT, store offline when connection is lost and automatically sync when network is available. The system supports configuring alert and sending thresholds Push Notification when it rains or parameters exceed limits, and also provides Dashboard, trend charts, user permissions and Export Excel report for remote management and monitoring.

MEI Smart Agro Weather is an IoT solution designed to monitor meteorological and environmental parameters for smart agriculture, greenhouses, farms and micro-meteorological stations. Equipment used STM32 microcontroller combine modem 4G LTE, transmitting real-time data to the platform MEI ECO through protocol MQTT, allowing remote monitoring and management on Web/App.

The system supports connecting sensors RS485 Modbus RTU or 4–20 mA, including wind speed, wind direction, precipitation, light intensity, temperature, humidity and can be expanded to integrate other environmental sensors. All data is collected periodically, stored locally when connection is lost and automatically synchronized to the server when the network is restored.

Equipment used solar energy source combines rechargeable Li-ion/LiFePO₄ batteries and algorithms Deep Sleep Helps optimize energy consumption, allowing continuous operation for long periods of time without needing mains power. The system supports configuring alert and sending thresholds Push Notification when detecting rain, strong wind or parameters exceeding limits, and providing Dashboard, trend charts, user permissions and Export Excel report, effectively meeting the need for environmental monitoring in smart agricultural systems.

TECHNICAL SPECIFICATIONS

1. General introduction

Solution MEI Group Smart Agro Weather designed for smart agriculture, greenhouses and micro-meteorological stations, help Monitor wind speed, wind direction, precipitation, light, temperature, humidity and data transmission directly to the MEI ECO server via 4G network.
Equipment used solar energy combine high capacity rechargeable battery, operate Stable - economical - no need for grid electricity, suitable for field areas, remote areas or independent farms.

2. System structure

  • Meteorological sensor cluster (MEI Weather Node):

    • Measure wind speed, wind direction, precipitation, light, temperature, environmental humidity.

    • Low energy consumption sensor, output RS485 or 4–20 mA.

    • IP65 waterproof case, long-term sun and rain resistance, suitable for outdoor environments.

  • Data Receiver & Transmitter (MEI Agro 4G Controller):

    • Microcontroller Industrial STM32/ESP32, integrated modem 4G (SIM7600/A7677S).

    • Periodically transmit data MEI ECO Cloud qua MQTT or HTTPS.

    • Smart energy saving mechanism:

      • Self DeepSleep between measurement/transmission cycles.

      • Only turn on 4G when sending data, then turns itself off to save battery.

    • Ghi log local data when network is lost and automatically synchronizes when regained.

  • Solar source:

    • 10–20 W solar panels charge for Li-ion or LiFePO4 battery 6.6 Ah – 12 Ah.

    • Ministry Smart MPPT charging, automatically shuts off when full and charges optimally according to light.

    • Works continuously >10 days without sunshine thanks to the super energy saving mode.

3. Outstanding features

  • Direct 4G data transmission: No need for gateway, compatible with current IoT infrastructure.

  • Super energy saving: DeepSleep + periodic data transfer consumes just a few mAh/day.

  • Self-powered solar: Operates completely independently, no need for grid power.

  • Various sensors: Measure 6 main weather parameters – wind, wind direction, rain, light, temperature, humidity.

  • Smart warnings: Send information about heavy rain, strong winds, and temperature exceeding thresholds via App/SMS.

  • MEI ECO platform integration: Synchronize data, store, analyze and display visually on Web/App.

4. Practical application

  • Station Automated agricultural meteorology for fields, farms, greenhouses.

  • Microclimate monitoring for high-tech agriculture, precision agriculture.

  • Independent mini weather station serves early warning of rain - wind - abnormal temperature.

  • Warning system for strong winds - heavy rain - lack of light The house grows vegetables, flowers, strawberries, and melons.

5. Integrate the MEI ECO ecosystem

The system is a part of it MEI ECO Platform, including:

  • MEI Weather Node (Solar + 4G) – solar environmental sensor.

  • MEI ECO Cloud / Web / App – Realtime monitoring, automatic warnings & reports.

  • MEI ECO API / MQTT Broker – integration with SCADA systems or other agricultural control software.
