The SGP41 is a highly versatile metal oxide gas sensor from Sensirion, integrating multiple sensing elements on a single chip. With exceptional sensitivity and precision, it detects a broad range of volatile organic compounds (TVOCs) in the air and provides equivalent CO2 (eCO2) output. The SGP41 delivers a fully calibrated air quality output signal, making it an excellent choice for environmental monitoring and air treatment applications.

Designed as a digital smart switch and regulation unit, the SGP41 is ideal for air treatment devices such as air purifiers. Using Sensirion’s advanced Gas Index Algorithm, the sensor’s output can automatically trigger the removal of indoor pollutants without the need for user interaction. This feature allows continuous monitoring of VOC levels, detecting potentially harmful air quality events that may go unnoticed by humans. Additionally, the SGP41’s ability to control air treatment devices based on real-time sensor data helps save energy by automatically deactivating devices once the air quality is restored.

Its compact design ensures seamless integration into various applications, including smart home systems, IoT devices, mobile devices, and home appliances. While primarily focused on detecting TVOCs, the SGP41 also provides eCO2 output, offering comprehensive insights into indoor air quality and environmental conditions.

Features:

• Operates with a supply voltage of either 3.3V or 5V.
• I2C (IIC) communication interface for smooth and seamless data transmission.
• High-sensitivity sensor for detecting TVOCs and providing eCO2 output.
• Compact and practical design, ideal for easy integration into various applications.
• Low power consumption of 40mA, ensuring efficient operation.
