Sensirion SEK-SEN69C Evaluation Kit

Sensirion SEK-SEN69C Evaluation Kit provides a development platform for evaluating the SEN69C all-in-one indoor air quality sensor module. The kit supports testing of particulate matter, relative humidity and temperature, VOC, NOx, HCHO, and CO2 measurements through the included SEN69C module and connection accessories.

The SEN69C combines multiple sensors in a compact form factor and measures up to 10 environmental parameters, including PM1, PM2.5, PM4, PM10, temperature, relative humidity, VOC Index, NOx Index, CO2, and HCHO. The Sensirion SEK-SEN69C Evaluation Kit requires the SEK-SensorBridge and works with the SEK-ControlCenter software for evaluation workflows.

The kit is ideal for indoor air quality development and evaluation, where designers require broad environmental measurement coverage from a single sensing platform. The SEN69C includes onboard algorithms and is well-suited for applications requiring IAQ standards support, such as RESET® and WELL Building Standard™, but CO2 is not compliant with those standards.
