Abstract：Accurate wrist wearable temperature measuring equipment is of great significance for health detection and disease prevention and control. External environmental factors have great interference on the measurement of infrared temperature sensor, so temperature compensation is needed. Therefore, an infrared temperature detection bracelet based on MLX90614 is designed, and its temperature compensation method is analyzed and studied.The mathematical model of armpit temperature, wrist temperature and environment temperature was established.Finally, it is proved that the method can correct the measurement error of wrist temperature well, and the maximum temperature deviation is not more than 0.1℃ within a certain range of ambient temperature.
