Abstract :
MSDI (molecular semiconductor-doped insulator) ammonia sensors have been investigated using cyclic optical excitation as multi-signal generation method. This method enables a selective quantification of both humidity in the range of 30-70 %rh and ammonia concentration in the range of 0-30 ppm with a single sensor at room temperature.
