由于疫情影響，我不得不在家工作。在冬天，我必須關閉門窗。我待的時間越長，二氧化碳的含量越高，這讓我有點頭暈目眩和懶惰。盡管CO2是一種無害氣體，但長時間處于高濃度CO2中的人會危害健康：在室內常見水平1000 ppm左右，您會開始感到疲勞和困倦；達到2000 ppm時，您將入睡并感到非常疲倦，無法進行任何工作。長時間接觸并集中注意力會導致和身體不適。
監測室內的二氧化碳水平實際上可能比我們的常識更重要，因此我制作了一個二氧化碳監測器，顯示室內的二氧化碳水平提醒我及時打開門窗以改善室內空氣。
監測CO2和TVOC的傳感器
在室溫下，二氧化碳（CO2）是一種無色，無味，不可燃的氣體，必須有一個專門的傳感器來監測。SGP30是用于室內空氣質量監測的氣體傳感器。SGP30可以檢測范圍很廣的H2，并將基于H2濃度計算出的等效二氧化碳讀數通過I2C返回給微控制器。SGP30能夠設置濕度補償以獲得更好的精度，因此需要外部濕度傳感器才能使用。此外，SGP30傳感器可檢測多種揮發性有機化合物（VOC），并返回總揮發性有機化合物（TVOC）讀數。
我將AM2302與SGP30配合使用。AM2302是一種數字溫度和濕度傳感器，非常常見且易于使用。
