ABSTRACT:
A method for operating a sensing device. The method comprising: a sensor film having an electrical resistance that is adapted to change in response to the presence of a predetermined condition; detecting the presence of the predetermined condition; measuring the electrical resistance of the sensor film at a first time; measuring the electrical resistance of the sensor film at a second time; determining a rate of change of the electrical resistance between the first time and the second time; and comparing the rate of change of the electrical resistance against a threshold value.
