Design of Environmental Monitoring System for Livestock Transport Carriage Based on STM32 and ZigBee

In view of the situation that it is impossible to monitor the carriage environment during the transportation of livestock, a set of environmental monitoring system for livestock transportation carriage based on STM32 and ZigBee is designed. The system is mainly composed of STM32F103 micro-control system, ZigBee wireless communication module, multi-channel sensor module, display module, buzzer alarm module, key module and power module, which can realize the functions of collection, transmission, display of temperature and humidity of the carriage, carbon dioxide concentration, abnormal alarm and so on. The test results show that the system operates stably, safely and reliably, and has high practical value.
