Abstract: Aiming at the disadvantages of redundant design, complex deployment, and high cost of existing monitoring systems, which are difficult to promote and use in smallscale poultry houses, an environmental monitoring system suitable for small and mediumscale poultry houses is designed and implemented. The lowpower WiFi technology was used to design the wireless monitor, which can provide the system with more accurate data collection. The monitor implements a periodic lowpower control strategy through different subtask processes. The backend server is based on the Raspberry Pi singleboard computer and adopts the Spring Boot framework based on Java language. While realizing the user interface, the server also uses the underlying hardware interface to control the environmental control equipment automatically. Longterm comparative tests show that the system can reduce the power consumption of poultry houses by 7.71% and reduce the rate of poultry elimination by 0.8%. The system has the characteristics of low hardware implementation cost, easy deployment, accurate and reliable environmental monitoring, which gives the system a high promotion and application value in small and mediumsized poultry houses.
