PURPOSE:To provide a carbon dioxide gas detector employing a carbon dioxide gas sensor in which maintenance can be facilitated. CONSTITUTION:The carbon dioxide detector 1 incorporates a solid electrolytic carbon dioxide gas sensor 2 connected with an op-amp circuit 3 which amplifies a voltage signal being delivered to a microcomputor 4. The mtcrocomputor 4 delivers a carbon dioxide gas concentration value to a D/A converter 5 which then delivers a corresponding voltage to a terminal block 6. A power supply 7 feeds power to the carbon dioxide gas sensor 2, the op-amp circuit 3, the microcomputor 4, and the D/A converter 5. |
