| Abstract: | How to measure low concentration carbon monoxide accurately and sensitive in air and how to send the single to checkpoint momently and cheaply are the questions we always concern.Aim at this concern,an spectrum absorption type gas sensor is studied.Using LED as light source,carbon monoxide gas concentration can be detected by modulating Fabry-Perot cavity's driving voltage and single wavelength doublepass difference absorbing.Based on wireless sensor network,carbon monoxide concentration can be monitor,appreciate and collect in the network district,realize long-distance monitor by CDMA network.Real-time on-line monitor is realized,the cost is lowed,and the efficiency is advanced. |
