Я иногда задавался вопросом, почему в зимюю пору утром бывает тяжелая голова. Прошлой зимой даже купил увлажнитель воздуха, думал это из-за сухого воздуха. Купив этот датчик и собрав прибор я понял что голова тяжелая из-за высокой концентрации СО2. В квартире с пластиковыми окнами за ночь конценрация СО2 поднимается до 1500-1800 ppm. Если окно оставлено на проветривание то концентрация СО2 на превышает 600-700 ppm. Рекомендую отключить автокалибровку и делать калибровку вручную раз в пару недель.
