SEN54
Environmental sensor node for PM, RH/T, VOC measurements
The SEN54 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), humidity and temperature. Thanks to proprietary algorithms, the module enables straightforward integration into various applications, which allows device manufacturers to save valuable project time and personnel resources and focus on their core competencies. On top of that, the SEN54 is compliant with the relevant healthy building standards RESET® and WELL Building Standard™ – for more information please refer to the application note "Compliance of Sensirion’s VOC Sensors with RESET and WELL" below.
Please note: Cables are not included. If cables are needed, please have a look at the SEK-SEN5x Evaluation kit.
