I am sorry if I went through the project description too fast. I'll go slowly. Our project is a infrared LED strip that heats patients during surgery since their body temperature drops when they are unconcious. In order to measure their body temperature we are incorporating an IR sensor into the control module that regulates the LED lighting. If the body temperature goes above critical, some of the LEDs will turn off automatically.
I did some research and found out about thermopiles and sensor modules and they look what I might need. Any suggestions
