Melexis MLX90632 Infrared Temperature Sensors

Melexis MLX90632 Infrared Temperature Sensors are non-contact temperature sensors in a small SMD SFN package that is factory calibrated to a high accuracy. The calibration constants used to calculate the ambient and object temperature are stored in the EEPROM memory. These MLX90632 temperature sensors store the raw information in RAM after processing, and the result of each measurement conversion is accessible via I²C. The external unit of these sensors utilizes the measurement data and calibration data to calculate both the sensor temperature and the object temperature.

The MLX90632 temperature sensor features a measurement resolution of 0.02°C, I²C compatible digital interface, 50° Field of View (FoV), and an integrated post-calibration option. The calibration of the MLX90632 temperature sensor can be adjusted to meet the requirements of the application in use, in case an optical window or obstructions are present.

This series is available in two different versions: standard and medical accuracy. The medical sensor is calibrated with an accuracy of ±0.2°C within the narrow object temperature range from 35°C to 42°C for medical applications. MLX90632 Medical sensor is ideal for medical thermometers, smart glasses, and smart headphones. The standard MLX90632 sensors application typically include industrial temperature control of moving parts, non-contact temperature measurements, and home appliances with temperature control.
