Description
The MLX90601C is a versatile IR thermometer
module, which performs signal conditioning,
linearisation and ambient temperature
compensation. The module is built around the
MLX90313 IR amplifier-interface, which uses
high performance, chopper stabilized amplifiers,
providing excellent noise performance. The
sensing element is the MLX90247 discrete IR
thermopile.
The module is delivered factory calibrated. The
SPI offers both the sensor ambient temperature
and the object temperature in 12 bit digital form.
Additionally the module offers several analog
pins for access to the programmable comparator
circuitry and the reference voltage.
