| Abstract: | CuPc is a kind of organic metal compound. It has the characteristic of semiconductor because of its structure, and its resistivity changes with NO2 gas. According to this, we produced sinter type of gas sensor with indirect heater. This kind of sensor has a reletively high sensitivity to NO2 gas, and is linear to NO2 gas within low concentration of NO2 gas. It can detect 5 mg/m3 of NO2 gas with rapid response (<25 seconds). It has a good selectivity, some other kinds of gases such as NH3, H2S, CH4, CH3CH2OH etc. and humidity almost does not disturb the detecting for NO2 gas. |
