A miniature far-infrared sensor, the MLX90632 from Melexis performs human body temperature measurement from 35°C to 42°C, accurate to within ±0.2°C. The noncontact sensor comes in a small 3×3×1-mm QFN package that makes it suitable for use in health-monitoring wearables and in-ear devices, as well as clinical point-of-care applications.
Using advanced compensation algorithms, the MLX90632 mitigates the effects of thermal disturbances to achieve a high level of accuracy and stability. Contained within its surface-mount package are the sensor element, signal processing circuitry, digital interface, and optical interference filter. This long-wave pass filter blocks visible and near-infrared radiant flux to ensure ambient light immunity.
The medical grade sensor has an object temperature range of -20°C to +100°C with an accuracy of ±0.2°C in the human body temperature range. A commercial grade version of the MLX90632 is also available. It covers an object temperature range of -20°C to +200°C with typical accuracy of ±1°C. The commercial version can be used in white goods, smart thermostats, and portable electronic devices.
