PLANTOWER DS-CO2-31S NDIR Digital CO2 Sensor Module

规格

Product Introduction

DS-CO2-31S is a digital carbon dioxide concentration sensor based on non-dispersive infrared absorption principle (NDIR). It can continuously collect and calculate the carbon dioxide concentration in the air per unit volume, and output it through a universal digital interface. This sensor can be embedded into various instruments or environmental improvement devices related to carbon dioxide concentration, providing timely and accurate concentration data.
