Evaluate our environmental sensor solutions.

Compile Your Own Evaluation Kit with Sensirion's Toolbox

Each SEK-Environmental Sensing evaluation kit can be compiled individually in just three steps: Order a Sensirion SEK-SensorBridge, choose your environmental sensor and download our SEK-ControlCenter viewer software to start measuring.

Please find here an overview of the new SEK-Environmental Sensing toolbox: PDF (view on mobile phone)

1. Buy a SEK-SensorBridge

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
