Indoor air quality is a growing concern, with pollutants like particulate matter, carbon dioxide, and volatile organic compounds posing health risks. Sensirion¡¯s SEN66 environmental sensor module addresses these challenges with a compact, integrated solution that measures multiple parameters efficiently.
Integrated Design and Capabilities
The SEN66, part of the SEN6x series, combines nine environmental measurements in a single module: PM1, PM2.5, PM4, PM10, temperature, relative humidity, VOC index, NOx index, and CO?. Its compact size (55.5 ¡Á 25.6 ¡Á 21.5 mm) and I2C interface make it suitable for various applications. Key specifications include:
- Particulate matter range: 0¨C1000 ¦Ìg/m3
- Temperature accuracy: ¡À0.45 ¡ãC
- Relative humidity accuracy: ¡À4.5 %RH
- CO? range: 0¨C40,000 ppm, accuracy: ¡À50 ppm
- VOC output: 0¨C500 VOC Index
Embedded algorithms simplify integration, reducing development time and costs while enabling user-friendly applications.
Innovative Particulate Sensing
At the core of SEN66 is the SPS6x MEMS particulate sensing component, which integrates light source, detector, signal processing, and algorithms into a single unit. This patented design measures four PM parameters (PM1, PM2.5, PM4, PM10) with high accuracy, offering a cost-effective and space-efficient solution.
Applications Across Industries
The SEN66 supports a wide range of applications, including:
- Smart Homes: Air purifiers, air quality monitors, smart speakers, thermostats, gateways
- Offices and Industry: Air purifiers, air quality monitors, conference audio systems, security cameras
- Schools: Air purifiers, air quality monitors, video conferencing systems, vape detectors
It also complies with standards like RESET, WELL Building Standard, and California Title 24 for indoor air quality.
Flexible and Scalable Solutions
The SEN6x series offers modular configurations to meet diverse needs, including:
- SEN60: Particulate matter
- SEN63C: Particulate matter, humidity, temperature, CO?
- SEN65: Particulate matter, humidity, temperature, VOC, NOx
- SEN66: Particulate matter, humidity, temperature, VOC, NOx, CO?
- SEN68: Particulate matter, humidity, temperature, VOC, NOx, formaldehyde
A single design can support multiple product tiers, streamlining production. The SEK-SEN66 evaluation kit enables rapid prototyping and testing.
