Take action against inadequate indoor environments!

Creating a comfortable, organized, and distraction-free working environment in the office is essential. Additionally, it should have comfortable temperature and humidity, good air circulation, reasonable sound levels, and stimulating spaces where productivity can thrive. In fact, according to the World Health Organization (WHO), environmental noise is the second most significant environmental cause of health problems after air pollution.

The Square Sound is a multi-purpose LoRaWAN multi-sensor ideal for taking action against poor indoor environments and noise levels.

This complete unit features temperature, humidity, sound, and air pressure sensors, as well as low power consumption for up to 10 years of battery life.

The sensor is also location-aware, making it ideal for mobile applications like trains, boats, caravans, etc., or notifying you if the sensor has been moved or removed. This functionality also simplifies installation and system configuration in the field.

The Square is easy to mount with the included adhesive or screws.

Square Sound LoRaWAN

Square Sound is an ultra-compact multi-sensor designed for monitoring sound levels and indoor climate in buildings and workplaces. It measures sound pressure levels (SPL), temperature, and humidity, enabling data-driven actions to improve comfort, productivity, and well-being.

By providing real-time, peak, and average sound measurements, Square Sound helps identify noise issues and trigger alerts when predefined thresholds are exceeded.

With a battery life of up to 10 years – designed for long-term, maintenance-free operation, it is ideal for continuous monitoring in professional environments.

Typical use cases

Sound level monitoring in offices and workplaces

Noise threshold alerts and compliance monitoring

Indoor climate monitoring (temperature & humidity)

Schools, hospitals, and public environments

Workplace optimization and well-being initiatives

Key advantages

Accurate sound measurement – real-time, peak, and average SPL monitoring

10-year battery life – designed for long-term, maintenance-free operation

Multi-function sensor – combines sound, temperature, and humidity

Discreet and compact design – easy to integrate into any environment

Easy configuration – via NFC using Sensative’s NFC app for Android

Installation

Square Sound can be mounted using the integrated adhesive for quick installation, or with the Sensative Square Screw Mounting Kit (optional) for secure and permanent mounting.

Smart geolocation (without GPS)

Square Sound supports cloud-based Wi-Fi geolocation, enabling positioning in indoor locations by scanning nearby Wi-Fi networks.

This functionality requires a compatible cloud service such as Sensative Yggio.
