Abstract
【解決手段】COセンサ1及びマイクロコンピュータ10で検出される検出濃度(ガス濃度)を、500ppm未満、500ppm以上1000ppm未満、1000ppm以上2000ppm未満、2000ppm以上の4つの区分に分類する。ガス濃度の測定を行うサンプリング処理の周期を、4つの区分に対応して、30秒、15秒、10秒、5秒に設定する。測定されるガス濃度が低濃度のときサンプリング処理の周期を長くし、高濃度になるほどサンプリング処理の周期を短くする。各サンプリング周期に対応して、サンプリング回数のデータをEEPROM50に記憶しておき、通信インターフェース60から外部機器100に出力して動作状況を確認できるようにする。
