Based on STM32F103 cowshed environment intelligent control system

Abstract

The environment of the barn affects the growth, health, reproduction and fattening of the cattle. In order to control the environment of the barn, an intelligent control system based on STM32F103 was designed to monitor and control the temperature, humidity and toxic and harmful gases such as SO2 and NH3. The system adopts STM32F103 as the control core; air pollution sensor MQ135, humidity sensor DHT11, temperature sensor DS18B20 is the system data acquisition device; air purification box (pump, condenser, heating plate, fan) is the system execution device, PC end data analysis software. The experiment was carried out in Mengniu dairy farm in Shengle Economic Development Zone, Hohhot City. The results show that the system can monitor and control various environmental factors stably and reliably.

Analysis of the Development Status and Prospect of China’s Agricultural Sensor Market under Smart Agriculture

“…At last, temperature, humidity, ammonia concentrations, hydrogen sulfide concentrations, carbon dioxide concentrations, sulfur dioxide concentrations and light intensity are the main parameters detected by environmental sensors integrated into breeding environments for poultry and livestock [ 34 ]. Environmental sensors should ideally be affordable, lightweight, modular and portable [ 35 ]. Currently, more wearable sensor technologies such as motion sensors and vital signs sensors are used within the breeding environment to collect, transmit and store information [ 36 ].…”
