Product Description:

YJJ MH-411D Infrared Carbon Dioxide Gas Sensor CO2 Concentration Detection Sensor Probe

Features:

MH-411D carbon dioxide gas sensor is a universal and intelligent infrared gas sensor (hereinafter referred to as the sensor). This sensor uses the non-dispersive infrared (NDIR) principle to detect the C02 present in the air. The sensor is oxygen-independent, has stable performance and a long lifespan. It is equipped with internal temperature compensation. This sensor is a small-sized high-performance sensor made by closely integrating mature infrared absorption gas detection technology with micro-machining and excellent circuit design.
