An integrated environment temperature sensor device provides improved temperature sensitivity by using a diode as the sensing element. The integrated sensor device comprises a heater element for creating a fixed quantity of heat energy. The sensor device also comprises an integrated circuit diode which receives the fixed quantity of heat energy from the heater element. The integrated circuit diode has a constant forward bias current applied thereto and a change in environment temperature is reflected in a voltage change across the integrated circuit diode. The integrated circuit diode further comprises an electrically insulating layer positioned substantially between the heater element and the integrated circuit diode for electrically insulating the two from each other.
