Abstract: This design by combining the ESP8266 and the LoRa module, overcomes the distance limitation of the traditional system, and realizes real-time collection of environmental information and remote control of equipment for free-range hen houses. The system adopts a LoRa-based data acquisition architecture to monitor key parameters, such as temperature, humidity, light intensity and harmful gas concentration in the hen house in real time, and realizes accurate monitoring through a distributed sensor network. In the event of an emergency or abnormal situation, the system will activate the alarm mechanism to ensure the safety of the hens. The system consists of two parts: host computer and lower unit. The self-made APP and OneNET cloudera data platform are collectively referred to as the host computer, which is mainly responsible for data upload and command release. The lower unit consists of a main engine with NodeMCU as the core and two Arduino slaves with LoRa modules. The host communicates with the cloudera data platform through ESP8266 module; the slave is connected to a variety of sensors and actuators to achieve real-time monitoring and control of the environment and equipment.
