Based on the proven MG-811 sensor core, its primary function is to act as a simple, threshold-based switch. An onboard potentiometer allows for the manual setting of a specific CO₂ concentration level. When the ambient CO₂ exceeds this preset point, the sensor provides a clear digital signal, making it straightforward to implement event-driven systems like safety alarms or ventilation controls. With a wide detection range of up to 10,000 ppm, it is well-suited for monitoring environments where CO₂ can accumulate to significant levels, such as fermentation chambers or mushroom cultivation tents.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSimple Threshold Alarm for High-CO₂ Events\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe CO2 detection module's core feature is its function as a simple comparator. By adjusting the onboard potentiometer, a user can define the exact CO₂ level that triggers an alert. When this threshold is crossed, the digital output (DO) pin changes state, providing an unambiguous \"go\/no-go\" signal. This allows for the creation of simple logic-based systems (e.g., IF CO₂ level is high, THEN activate relay) without needing complex code to interpret analog data.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWide Detection Range for Specialized Environments\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEngineered to perform in environments far beyond typical room air, this sensor can detect CO₂ concentrations up to 10,000 ppm.
