Dual output functionality This carbon dioxide sensor module provides both analog and level outputs, enabling compatibility with a wide range of microcontroller systems. This versatility supports easy integration in different projects and hardware configurations. Temperature compensation With temperature compensation, the sensor maintains measurement accuracy as ambient conditions change. This helps reduce drift and improves reliability in realworld environments. Active low signal The digital level output is active low, simplifying connection to common microcontrollers and reducing wiring complexity during implementation. Wide voltage output range The analog output is 0 to 2 V, allowing easy interfacing with devices that require different voltage levels for interpretation. This makes it straightforward to adapt to various ADC inputs and system designs. Use scenarios Indoor air quality monitoring in smart homes or offices: sense CO2 levels with a microcontroller and trigger ventilation or alerts to maintain comfortable and safe environments. Greenhouse or plant growth applications: monitor CO2 concentration and control environmental systems to optimize plant health and yield. Laboratory experiments and HVAC diagnostics: log CO2 data and use the digital output to generate alarms or automate control processes in experimental or building systems.
