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 features 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.
Features
- Digital gas sensor: The SGP41 is a digital gas sensor that can measure the concentration of volatile organic compounds (VOCs) and nitrogen oxides (NOx) in indoor air
- CMOSens® technology: The SGP41 uses Sensirion's CMOSens® technology, which offers a complete and easy-to-use sensor system on a single chip
- Long-term stability: The SGP41 has outstanding long-term stability and lifetime, making it ideal for applications that require continuous monitoring of indoor air quality
- Digital output signals: The SGP41 provides digital output signals, which makes it easy to integrate with microcontrollers and other digital systems.
- Small form factor: The SGP41 is very compact and suitable for applications with limited space. It features a 4-pin Grove interface that allows users to easily connect the sensor to a microcontroller
- Flexible power supply: The module supports both 3.3V and 5V power supply, making it very flexible and easy to use in different applications
- High reliability and reproducibility: Sensirion's state-of-the-art production process guarantees high reproducibility and reliability of the SGP41 module
- Product number: Seeed 101021092
