| Abstract: | In the paper,a wireless data transmission module based on LoRa technology is designed.The module uses SX1278 as the radio frequency chip and STM32H743 as the main control chip.Aiming at LoRa's half-duplex communication,a synchronous time-division data receiving and sending mechanism is designed to realize long-distance real-time two-way communication.At the same time,a method for module adaptive transmission power is proposed,which reduces the power consumption of the module.The measured transmit power of the module is 17 dBm,the power consumption is 287.1 mW,the reliable communication distance of the module is up to 4.6 km,and the weight is less than 3 g. |
