T6703 NDIR CO2 Sensor Module Carbon Dioxide Sensor 0~5000PPM For Residential Applications
Version Comparison:
* T6703 CO2 Module: It is configured for applications where CO2 levels are less critical but an assessment of indoor air quality is required, for example in residential applications. Our minimum order requirement reflects the high volumes of these applications.
* T6713 CO2 Module: It is ideal for applications where accurate CO2 levels need to be measured and controlled for indoor air quality and energy saving applications, such as demand control ventilation.
