This study proposes a multi-channel reception system for greenhouse environmental monitoring data based on LoRa wireless communication technology. Various sensors are installed inside the greenhouse to monitor environmental information such as temperature, humidity, soil pH, CO2 concentration, etc., which are then converted into electrical signals. These signals are transmitted and received by the reception system, which then sends them to terminal devices for display or further processing. The reception system consists of a front-end circuit and a reception module. The front-end circuit performs preliminary processing on the signals received by the antenna, while the reception module is composed of an STM32 microcontroller and the LoRa transceiver chip SX1278. The circuit schematic was designed, and a PCB was fabricated. The actual test results met the expected requirements. The system exhibits good scalability, allowing for the flexible addition or reduction of reception channels based on actual needs, making it suitable for greenhouse monitoring scenarios of different scales. Additionally, its hardware interfaces and communication protocols are universal, facilitating integration with existing greenhouse management systems for data sharing and collaborative control.
