The MLX90632 is based upon Melexis' established far infrared (FIR) technology that utilises the fact that all objects emit heat radiation.
Miniaturised far-infrared sensors tend to be sensitive to thermal disturbances, however, the MLX90632 mitigates this effect through sophisticated compensation algorithms; delivering high levels of thermal stability. The medical-grade MLX90632 has been optimised for the normal human body temperature range, where it offers medical-grade accuracy of ±0.2°C thanks to advanced in-factory calibration procedures.
The ultra-small device is a complete solution in a 3x3x1mm QFN package which includes the sensor element, signal processing, digital interface and optics thereby allowing rapid and simple integration into a wide variety of space constrained modern applications.
The small size, high thermal stability and optimisation for human body temperature make the MLX90632 suitable for ultra-small modern health monitoring devices, such as portable diagnosis tools capable of monitoring body temperature continuously. Monitoring vital signs repeatedly is a key enabler of preventive medicine practices to detect early critical health conditions.
The sensor is also highly suited for more classic medical devices such as forehead or ear body thermometers.
