| Abstract: | This article describes the design of a portable multi-gas detector. The design uses PIC18LF6620 as core processor, continuously detecting O2, CO, H2 S, CH4 gas concentration. The gas sensor working principle and its signal processing circuit are introduced. The program is tested, and the detector has advantages of small size, light weight, high sensitivity, fast response and accurate measurement. |
