If LEDs used, negative temperature can be shown on blue LEDs and positive on red LEDs. Advanced variant - big model of thermometer (up to 10 m long).

Temperature can be read with DS18B20 sensor, and there can be light sensor (for model lighting while dusk). If there is winch used in model, it's positon should have manual or automatic calibration and position sensor.
