Design of ear tag type pig temperature monitoring system based on WiFi

Abstract：Traditional pig temperature measurement generally uses a mercury thermometer to measure the rectal temperature of the pig to determine the body temperature. This method cannot achieve real-time monitoring of the pig temperature. The system designed a pig temperature monitoring system based on the Internet of Things technology. The ESP8266 is used as the main controller and wireless communication module. The temperature sensor uses MF54 series NTC thermistor. The software and hardware adopt unbalanced bridge circuit and average filtering method, so that the accuracy of the measured data reaches ±0.1 ℃. Due to the activity of live pigs, the monitoring node is integrated on the ear tag of the pig, and the real-time monitoring of the body temperature is achieved by collecting the ear cavity temperature. The platform layer uses the mobile OneNET IoT platform, and develops a mobile application as the display terminal of the monitoring system. This system realizes real-time monitoring of pig body temperature, which has certain application value for pig disease prevention and intelligent breeding.
