Sensirion Particle, VOC, Humidity, and Temperature Sensor - SEN55
All prices are VAT included
The SEN55 environmental node is a straightforward, all-in-one sensor solution platform for the accurate measurement of various environmental parameters, such as particulate matter, volatile organic compounds (VOCs), oxidizing gases, such as nitrogen oxides (NOx), as well as humidity & temperature.
Thanks to proprietary algorithms, the module enables straightforward integration into various applications. This allows you to save valuable project time and personnel resources compared to integrating all of these separately. The SEN55 provides reliable air quality measurement data.
**Note:** We provide an interface cable as well. A feature not found elsewhere.
