Product description
The MLX90637 is a non-contact infrared tempera-ture sensor in a small SMD Chip-scale package. The device is factory calibrated with calibration constants stored in the EEPROM memory. The ambient and object temperature can be calculat-ed externally based on these calibration constants and the measurement data.
The MLX90637 is highly resistant to temperature fluctuations in its environment, ensuring accurate measurements. Localized thermal variations, such as air turbulence, will not affect the thermopile's output signal.
The supply voltage of the MLX90637 is 3.3V. For the I2C communication with the master microcon-troller, the MLX90637 supports 3.3V I2C bus volt-age.
An optical filter is integrated in the sensor to pro-vide ambient light immunity. The wavelength pass band of this optical filter is from 2 to 20μm.
To facilitate development, an Evaluation Board (Datasheet of EVB90637) is available.
