MLX90616 Infra Red Temperature Sensor problem
The MLX90616 does not come factory calibrated as such all the calibration co-efficients are set to zero by default. This means that the Object temperature readings will not respond to fluctuations in temperature. In order to get readings from this particular sensor a calibration procedure must first be performed and the co-efficients written to the appropriate EPROM locations. You need to contact your supplier for further details on the calibration procedures.
