MG811 Air Carbon Dioxide (CO2) Sensor Module

MG811 Air Carbon Dioxide (CO2) Sensor Module The MG811 CO? Sensor Module is an electrochemical gas sensor designed to detect and measure carbon dioxide (CO?) concentration in the air. It operates based on a solid electrolyte and produces an analog output that varies with CO? levels. The sensor requires a stable power supply and proper warm-up time to deliver reliable readings. Due to its sensitivity and relatively wide detection range, the MG811 is widely used in indoor air quality monitoring, environmental sensing, and HVAC systems.Click here to view related productsFeaturesDetects carbon dioxide (CO?) concentrations in airAnalog output proportional to CO? levelHigh sensitivity with measurable response over a useful rangeStable and repeatable performance with proper conditioningLong service life when used within specificationSuitable for indoor air quality sensingStandard interface for analog signal measurement (ADC required)Relatively low cost for CO? sensing applicationsTypical ApplicationsIndoor air quality monitoring (homes, offices, classrooms)Greenhouse CO? control and plant growth systemsHVAC ventilation control and demand-controlled ventilationEnvironmental and pollution monitoringSmart home air quality alertsPortable CO? measurement devicesEducational and hobbyist electronics projectsEmbedded and IoT environmental sensor systems*Product image for illustration purposes only, actual product may vary.
