Product Description
MG812 Carbon Dioxide Gas Sensor
The MG812 is a compact semiconductor oxide chemical sensor utilizing solid electrolyte battery technology for precise CO2 detection. This mini-sized sensor operates with low power consumption, making it ideal for various monitoring applications.
Operating Principle
When maintained at optimal operating temperature and exposed to CO2 atmosphere, the sensor's electrodes generate an electromotive force. The output signal voltage inversely correlates with the logarithm of CO2 concentration, enabling accurate detection of concentration changes through voltage measurement.
Key Features
- Solid electrolyte battery principle for reliable CO2 detection
- Miniature size design for space-constrained installations
- Low power consumption with heating power of 420mW±50mW
- Wide operating temperature range from -20℃ to 50℃
- Semiconductor oxide chemical sensor technology
Application Areas
Ideal for air quality control systems, fermentation process monitoring, greenhouse environmental control, and various industrial applications requiring precise CO2 concentration detection.
