Aiming at the problems of short communication distance

high power consumption and complicated network of aquaculture wireless water quality monitoring system

a novel aquaculture water quality monitoring system is proposed. Taking the STM8 L low power consumption microcontroller as the core and combining with the LoRa modulation technology to customize the network communication protocol

wireless sensor networks（WSNs）node with low power consumption and long distance is designed

and the collection and transmission of water quality parameters for aquaculture are completed. Low power consumption design of hardware and software is introduced. System energy consumption

communication distance are tested. The experimental results show that the water quality monitoring system has obvious advantages in coverage range and power consumption. LoRa communication technology provides possibilities for the formation of large-scale low power consumption WSNs in the future

and has a very good promotion value in smart agriculture.
