        At present, the environmental regulation of Taiwanese traditional poultry farm is based on the information collected by the ambient temperature and humidity sensor. However, this method is unable to know the situation of the poultry directly. The purpose of this study is to collect poultry body surface temperature information directly by the infrared thermal imager. The relationship between poultry body surface temperature and temperature-humidity index (THI) is studied for estimating the actual feeling of poultry at different conditions. The Raspberry Pi, infrared thermal imaging sensor, environmental sensors were integrated for collecting the poultry body temperature and environmental information. The collected poultry infrared thermal images were divided into head, foot and wing different areas for the analysis. The environment temperature, humidity, air velocity and poultry surface temperature were continuous recorded for four weeks. The measured chicken’s surface temperature from infrared image sensor changes with the THI. The temperature change of the chicken’s foot is larger than the temperature of chicken’s head, and wing. The correlation between poultry surface temperature and THI, and temperature-humidity-velocity index (THVI) were calculated. According to the results, the correlation between poultry surface temperature and THI is higher than the correlation between poultry surface temperature and THVI. It shows that THI impacts on the poultry surface temperature. The poultry surface temperature can be detected by the infrared camera for poultry house environment control.
