A method and system for expanding the range of working environments in which a 3-D or depth sensor can operate without damaging or degrading the measurement performance of the sensor are provided. The sensor has a rigid support structure and a plurality of optoelectronic components fixedly supported on the support structure. The system includes an enclosure for enclosing the support structure and the supported optoelectronic components within an interior of the enclosure. A temperature control circuit includes a controller to monitor interior temperature within the enclosure and to regulate temperature within the enclosure to be within an operational temperature range of the sensor based on the monitored temperature.
