Click [here](https://sensirion.com/products/catalog/SFM3505) to learn more about the Sensirion SFM3505 sensor.
The default I²C address of [SFM3505](https://sensirion.com/products/catalog/SFM3505) is **0x2E**.
## Connect the sensor
You can connect your sensor over a [SEK-SensorBridge](https://developer.sensirion.com/product-support/sek-sensorbridge/).
For special setups you find the sensor pinout in the section below.
