STM32 and LoRa-based wireless sensor network for precision agriculture

Here, we are building and monitoring the soil level with current humidity and temperature using the features and technology of LoRa-based RF networks and IoT-based technology so that end users can monitor their precise farming and can efficiently irrigate their crops with the aid of an IoT mobile app. For communication between the agriculture node and the LoRa gateway node, this system uses LoRa RF technology. It has low power requirements, high data transfer rates, a long communication range to cover a bigger region, flexible and accurate measurement features, and real-time monitoring. It has the ability to send sensor data using encryption and decryption techniques for secure communication, and ESP8266 has the ability to send all data to the end user over a public network so that they can access the IoT mobile app Dashboard and control it manually or automatically.
