This is a digital gas sensor that uses Sensirion's SGP41 with advanced CMOSens technology to measure VOCs and NOx in indoor air. It is highly stable and durable, making it suitable for continuous monitoring over extended periods. Its compact size and flexible power supply options make it easy to use in various applications such as air purifiers and demand-controlled ventilation systems.
Indoor air pollution can have a significant impact on our health, and it's important to be aware of the harmful pollutants that can be present in the air we breathe. One of the most concerning pollutants are volatile organic compounds (VOCs) and nitrogen oxides (NOx). These gases can come from a variety of sources, such as cleaning products, paints, and cooking fumes, and can accumulate to dangerous levels in poorly ventilated indoor spaces.
The Grove - Smart Air Quality Sensor is an essential tool for anyone who wants to monitor and improve their indoor air quality. It is a fully integrated MOX gas sensor that is designed as a digital smart switch and regulation unit. It measures VOCs and NOx in indoor air for air treatment devices such as air purifiers. It utilizes Sensirion's SGP41, which processes two sensor signals using a powerful Gas Index Algorithm. The signals can directly trigger air treatment devices to remove indoor air gas pollutants without the need for user-device interaction.
This sensor solution is ideal for continuously monitoring VOC and NOx levels, including potentially harmful events that are imperceptible to humans. Additionally, the SGP41 signals can automatically control air treatment devices, saving energy by turning them off once VOC and/or NOx levels have been addressed.
By using this sensor, you can take proactive steps to reduce your exposure to these harmful gases and protect your health. Especially for NOx indoor gas pollutants, which may cause or facilitate various diseases mainly related to respiratory issues when exposed over a prolonged time.
