CO2 Sensor
Application:
HVAC and indoor air quality monitoringProduct characteristics:
High sensitivity, high resolution, fast response timeProduct Description
TX721-A2 infrared carbon dioxide gas sensor is a general-purpose intelligent infrared gas sensor (hereinafter referred to as sensor). The sensor uses the non-dispersive infrared (NDIR) principle to detect CO2 in the air. The sensor has no oxygen dependence, stable performance and long life. Built-in temperature compensation. The sensor is a compact and high-performance sensor made by closely combining mature infrared absorption gas detection technology with micro-machining and sophisticated circuit design.
