Grove SGP41 Air Quality Sensor

The Grove - Air Quality Sensor (SGP41) is a digital gas sensor that utilizes Sensirion's advanced CMOSens technology to measure volatile organic compounds (VOCs) and nitrogen oxides (NOx) in indoor spaces. It is highly stable and durable, making it suitable for continuous monitoring over extended periods. Thanks to its compact size and flexible power supply options, it is easy to use in various applications such as air purifiers and demand-controlled ventilation systems. This sensor is ideal for anyone looking to monitor and improve indoor air quality. It reliably measures VOCs and NOx and can directly trigger air treatment devices to remove pollutants from the air. With the SGP41, you can proactively take steps to reduce your exposure to these harmful gases and protect your health. The sensor is easy to integrate and provides precise and repeatable results.

Features: 

• The sensor measures the concentration of VOCs and NOx in indoor air and provides accurate and reliable readings. 
• The CMOSens technology integrates a complete sensor system on a chip, enhancing user-friendliness. 
• The sensor offers exceptional long-term stability and durability, ideal for continuous air quality monitoring.
