Air Quality Sensor VOC and NOx Gas Sensor 5V 6-Pin Tray
Sensirion’s all-in-one air quality sensor SEN5x
The SEN5x family, represented by the SEN50, SEN54 and SEN55, is an air quality sensor solution platform for the accurate measurement of various environmental parameters, such as particulate matter, volatile organic compounds (VOCs), nitrogen oxides (NOx), as well as humidity & temperature.
Thanks to its proprietary algorithms (temperature and humidity compensation, VOC index calculation), the SEN5x enables a compact, easy and fast integration into various applications. It comes with an I2C interface, supply voltage of 5 volts and can operate for more than 10 years in a wide range of temperatures (-10 to 50 °C).
The particulate matter sensor measures PM1, PM2.5, PM4 and PM10 with a superior lifetime and compact form factor
Popular applications include:
- Air purifiers
- Air quality monitors
- Air conditioners
- HVAC / ventilation systems
Air purifiers
The SEN5x sensor is perfect for air purifiers as the integrated index concept of the VOC and NOx outputs indicates when, how strong and how long purification is necessary.
Air quality monitors
As the SEN5x combines 5 sensors for the measurement of particulate matter, volatile organic compounds (VOCs), nitrogen oxides (NOx), as well as humidity & temperature it provides a more accurate and smarter feedback of the indoor air conditions of a monitored space.
Air conditioners
HVAC / Ventilation Systems
| Technology | Benefits |
|---|---|
| All-in-one environmental node: no co-integration of separate sensor components required | Faster time-time-to-market, less R&D expenses, bill of material and assembly costs |
| Integrated algorithms: temperature and humidity compensation, VOC Index calculation | Reliable and trustworthy measurements |
| Sheath-flow technology combined with high-quality components (incl. SHT4x and SGP40) | Dust-protection and long lifetime |
| STAR Engine (Sensirion Temperature Acceleration Routine)* | Accelerates the device’s response to ambient temperature change by a factor of 2-3 to provide better UX and more accurate measurements to end users |
* The STAR Engine is only implemented in the SEN54 and SEN55, not in the SEN50.
The SEK-SEN5x evaluation kit has been designed to help you evaluate Sensirion’s SEN5x environmental nodes easily and cost-efficiently. The kit contains the SEN5x sensor node, which is equipped with particulate matter sensing technology, an SGP41, an SHT4x humidity sensor and a microcontroller featuring VOC and NOx Index, relative humidity, and temperature outputs via I²C interface.
The SEK-SEN5x evaluation kit includes two cable sets. The “adapter cable” allows you to connect to a computer via the SEK-SensorBridge, which must be bought separately and can be ordered on the Arrow website.
Sensirion’s SEK-ControlCenter viewer software can be used for evaluating the sensor. In addition, the kit includes a jumper cable that enables fast prototyping, e.g., through integration into existing platforms (like Arduino, RaspberryPi, etc.). The software and relevant documentation can be downloaded from the Sensirion website.

Additional Notes
The SEK-SensorBridge allows you to connect suitable Sensirion sensors to a computer. It works hand-in-hand with the SEK-ControlCenter software. There are two ports on the SEK-SensorBridge, allowing you to connect sensors. You can connect more than one sensor to each port, provided that the sensors have different I2C addresses.
Important: For evaluating particulate matter sensors (SEK-SPS30), VOC sensors (SEK-SVM40) and formaldehyde sensors (SEK-SFA30) no SEK-SensorBridge is needed.
