CO2 Koolstofdioxide sensor 0-5000 ppm NDIR MH-Z19B met JST-micro 7P kabel

Beschrijving

Ter info:

– de aansluiting van de kabel kan ook “afgebroken” worden, zodat pin headers gesoldeerd kunnen worden.

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.
