Surface-contact temperature measurement technology is very successful, but the survey on the non-contact temperature measurement technology is also relatively less. Based on MLX90614, this system surveyed and analyzed a noncontact temperature measurement system, which uses embedded hardware platform Atmega328 and the system applies embedded IIC (Inter-Integrated Circuit) bus module's communication procedure and control methods. Experimental analysis of survey show that the system is of high stability, speed, and precision. The system may be widely used in many applications such as fault diagnosis, performance testing, etc.
