You cannot set a temperature threshold on a RealSense camera via the SDK; instead, you can read the internal temperature and use the information to determine if the camera is operating within safe limits. The laser will automatically adjust power or shut off if the projector temperature exceeds a threshold (around \(60^{\circ }C\)) to protect the camera. You can access the temperature values like rs.option.asic_temperature or rs.option.projector_temperature through the SDK, for example, by using sensor.get_option() in Python. How to get the temperature Start streaming: Begin streaming from the camera using rs.pipeline() and pipeline.start().Get the sensor: Obtain the sensor object for the depth sensor using pipeline_profile.get_device().first_depth_sensor().Access the temperature option: Call sensor.get_option() with the appropriate option. For example, to get the ASIC temperature, use rs.option.asic_temperature.For D400 series: Use rs.option.projector_temperature or rs.option.asic_temperature.For L500 series
