Abstract

The change of environment temperature and the variable of the sensor’s working temperature take great effect on the detecting precision

the stability and repetition of SnO

serial sensors.By controlling the power of internal heating resister with digital PI arithmetic

the sensors work at an invariable temperature

the temperature interfere can be restrained and stability of the sensors can be improved.The experiment results of the detecting gas CH

with show the methods can utterly keep the sensors from temperature interfere and enhance the sensor’s stability.
