Does the sound sensor take up one of the Sensedge Go's module bays?

No. The sound sensor does not take up a module bay used for air quality parameters. It is a separate add-on that sits inside the Sensedge Go alongside the air quality modules, so adding sound does not require you to remove or give up any air quality parameter.

If your devices are already deployed and measuring parameters such as O3, CO, and NO2, you can add sound on top of what you already measure. From the outside, the device looks the same, because the sound sensor is fully enclosed within the case.

The sound sensor is available as an add-on for the Sensedge Go (SE-300 and SE-300W). It is also offered on the wireless Sensedge Duct and Sensedge Go for Outdoors variants.
