このアプリは「換気エアミエル」CO2センサーを使って換気の見える化を可能にするものです。 「換気エアミエル」の詳細情報、御購入はこちらです。 https://www.stepone.co.jp/products/kanki-airmier/ 人は呼吸でCO2を吐き出すため密閉した部屋ではCO2濃度がどんどん高くなります。 CO2濃度が少し高まると、眠気を感じる程度ですが、さらに高まると、頭痛・めまいを起こしたり、気分が悪くなるなど、身体で感じるレベルの影響が出始めます。 換気エアミエルは、CO2濃度をチェックし換気状況を見える化するためのシステムです。 最大10個までセンサー値を同時表示できるため、換気状況を一括して見える化し、定期的に換気を促すのに役立ちます。 また最近では、人が増えるとCO2濃度も増えるということからCO2濃度の測定は、接触機会低減の指標としても参考にされています。
