The Grove - CO₂ Sensor (MH-Z16) is a high-sensitivity, high-precision infrared CO₂ sensor based on Non-Dispersive Infrared (NDIR) technology. It measures carbon dioxide concentrations ranging from 0 to 2000 ppm with a high resolution and a typical accuracy of ±200 ppm. Featuring a compact design, built-in temperature compensation, and UART digital output, it is ideal for HVAC systems, indoor air quality monitoring, industrial safety, and agricultural applications.

Workplace Air Quality Evaluation
| CO₂ Concentration | Environmental Condition |
|---|---|
| 350–450 ppm | Typical outdoor air |
| 350–1000 ppm | Fresh indoor air |
| 1000–2000 ppm | Stale air; may cause drowsiness |
| 5000 ppm | 8-hour exposure limit for safety |
Important Note
The Grove - CO₂ Sensor (MH-Z16) provides approximate CO₂ trends and is suitable for prototyping, environmental sensing, and educational projects. For applications requiring high-precision certified measurements, more advanced analytical instruments are recommended.
