compensation. The module is built around the
MLX90313 IR sensor 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
output is an absolute analog voltage output for
both sensor ambient temperature and the object
temperature. The REL1 output is the open drain
relay driver output available in MLX90313.
