Overview
Square Sound measures sound pressure level in dB, both average and peak, and can raise an alarm when a threshold is crossed or wake on sound. It never records audio: only levels leave the device. Alongside it, precise temperature (±0.2 °C) and humidity (±1.8 % RH) sensing means one device covers acoustic comfort and indoor climate.
Use it where noise matters: classrooms, open-plan offices, hotel rooms and short-term rentals, where a night-time alarm can trigger a call before the neighbours do. 15 mm thick with a 4,000 mAh battery for ten years of operation, NFC for local set-up and Wi-Fi geopositioning to know where it is. Mount with the integrated adhesive or the optional screw kit.

Key features
- ✓Levels, never audio: Reports sound pressure only. Nothing is recorded, so it can sit in a classroom or a rented flat.
- ✓Average, peak and alarms: Track trends over time or act on a threshold the moment it is crossed; wake-on-sound for event detection.
- ✓Climate included: Temperature and humidity from the same sensor as Square Comfort.
- ✓Ten years, no maintenance: 4,000 mAh battery in the 15 mm housing.
Zubehör
- Square screw mounting kit: Zwei Klebeplatten, um jeden Square-Sensor dort zu verschrauben, wo Klebeband nicht ausreicht — hinter dem Gerät oder daneben. Details
