Thermopile Infrared Sensor
MLX90247
The MLX90247 Thermopile Infrared Sensor uses a
thermopile to sense the temperature difference
between object and detector, and a thermistor for
measurement of the detector’s own temperature.
Calculation of the absolute object temperature is
possible through the combination of both outputs.
The MLX90247 is supplied uncalibrated.
Features and Benefits
• Contact-less temperature measurement based on infrared
emission by the object.
• High reliability fully CMOS-compatible process.
• Thermistor integrated in the thermopile sensor chip for
optimal tracking of sensor temperature.
• Nitrogen-filled hermetic TO-39 package.
• Coated silicon window for >75% infrared transmission in
the wavelength interval 5.5 µm to 14.5 µm.
• The silicon window blocks visible light and short-
wavelength infrared light emitted by infrared
communication devices.
• Automotive qualified.
• ESD sensitivity: up 8 kV
Applications
• Automotive climate control and windshield anti-fog
sensing
• Residential / Industrial climate control
• Medical and bio-instrumentation
• Industrial process control
• Consumer applications: microwave oven, hair dryer
• Detection of occupancy or movement
• High speed temperature change detection
