Introduction: The DS-CO2-20 is a digital CO2 concentration sensor based on the principle of non-dispersive infrared absorption. It continuously collects and calculates the concentration of carbon dioxide in air per unit volume and outputs it as a universal digital interface.The sensor can b..
Note:
When you receive this sensor, the surface is covered with a blue protective film. When you peel off the film, you can see the stainless steel case.
Working principle:
This sensor uses the principle of light scattering. That is, the illuminates the suspended particles ..
Features : - Sensitive material MQ-6 gas sensor is used to clean the air in the lower conductivity of tin dioxide (SnO2). When there is the environment in which the combustible gas sensor , conductivity sensor with increasing concentration of combustible gases in air increases . ..
Features : - MQ-8 gas sensor sensitive material used in clean air conductivity is lower tin dioxide (SnO2). When the sensor is present in the environment in which the combustible gas, the sensor's conductivity increases with the concentration of combustible gases in air increases. - Us..
