Detail Information

Product Introduction

 

The SMD-RMA8 series infrared carbon dioxide sensor uses the non-dispersive infrared (NDIR) technology to detect carbon dioxide in the air.

 

Main Application

 

SMD-RMA8 can be widely used in indoor and outdoor air quality detection and ventilation control systems, carbon dioxide gas monitoring in public location, Internet of Things gas information collection, agricultural production, cold chain transportation and other related fields.

 

Sensor Characteristics

 

● Good selectivity

● Long life time

● High consistency

● No oxygen dependence
