Abstract: To solve the problem of monitoring the temperature and movement of cattle and the environmental information of the cowshed in the precision breeding, a cattle breeding monitoring system based on a single chip computer was designed. The system took the Arduino single chip computer as the control center, and used temperature sensors, motion sensors, temperature and humidity sensors, sound sensors, and harmful gas sensors to collect the temperature information, movement information, and environmental information of the cowshed, The collected data were transmitted to the data center through ZigBee network to realize real-time monitoring of cattle temperature, movement status and cowshed environment.
