Abstract
The growing interest in detecting specific volatile organic compounds (formaldehyde, toluene, xylene, etc.), toxic or even carcinogenic, involves new techniques to ensure both selectivity and sensitivity of gas sensors. Furthermore, the indoor pollution monitoring requires small, low power and wireless module. Looking at novel metal oxide (MOX) gas sensors, the working temperature is critical for selectivity. Its good regulation ensures an optimized tradeoff between the response time, the recovery time and the sensitivity [1] . Finally, the baseline resistance is humidity dependent and requires compensation.
