Abstract
A metal oxide sensor employing a method of heating that reduces the power required to heat the sensor to an optimal operating temperature and a method to automatically regulate and maintain the temperature of the sensors in the presence of air currents and other ambient conditions. The ultra miniature metal oxide sensors used have a thermal time constant short enough to allow for heating of the ultra miniature metal oxide sensors to occur with very narrow pulses of electricity. Such narrow pulses used to heat the sensor and to maintain the temperature such that the methods for reducing the power requirement apply throughout sensor's operation.
