Product Description
MH-Z19B carbon dioxide gas sensor (hereinafter referred to as the sensor) is a general-purpose smart small-scale sensor that uses non-dispersive infrared (NDIR) principle to detect the presence of CO2 in the air, with good selectivity and anaerobic Gas dependence, long life and other characteristics; built-in temperature compensation; at the same time with serial output, analog output and PWM output, easy to use. The sensor is a high-performance sensor that combines mature infrared absorption gas detection technology with precise optical path design and sophisticated circuit design.

    Рекомендую продавца: заказывал много датчиков, дисплей и нано. Всё объединили в одну посылку, которая дошла до Набережных Челнов за 13 дней. Упаковано хорошо – всё дошло целым. Испытаю – отпишусь

    В Москву с момента оплаты доехало за 30 дней. Все работает, уже удалось собрать простой прототип. Цифры похожи на реальные. Сравнить, к сожалению, не с чем.

    Датчик шёл почти 2 месяца из-за коронавируса и нового года, но это не вина продавца. Упакован был в стандартный пупырчатый конверт, правда удивило, что просто лежал в нём без пакетика на молнии, т.е. вообще без защиты от внешних факторов.

    Быстро приехал. Все работает. Но понадобилось отключить автокалибровку (ABC) и на открытом воздухе откалибровать на 400 ppm (set zero point). Все настройки доступны через serial.

    Набор для метеостанции по проекту Alex Gyver. Очень долгая отправка – больше 20 дней. После отправки посылка доставлена за 17 дней в Москву. Трек отслеживался.
