2. Description
At the heart of the MLX90247 thermopile sensors is a
silicon die with a central micromachined membrane
surrounded by a bulk silicon edge. The hot junctions of the
thermopile are positioned near the center of the membrane
and the cold junctions are located above the bulk silicon
edge. Infrared irradiation of the low thermal conductivity
membrane creates a temperature difference between the
membrane and the surrounding bulk silicon. The resulting
thermopile voltage is a function of the temperature
difference
Measurement of the absolute temperature of the object is
possible by relating the thermopile signal
temperature of the sensor. The exact temperature of the
sensor is measured by a PTC thermistor integrated in the
bulk silicon edge. No supply voltage is needed for the
thermopile.
The sensor and thermistor can be used independently of
each other if desired, as the thermopile potential is floating.
