Air quality sensor

An air quality sensor measures environmental data such as CO₂ concentration, volatile organic compounds (VOCs), and particle levels in the air to monitor indoor air quality. In building automation, these sensors provide precise real-time data that is used to control ventilation and climate systems based on demand. This not only improves air quality but also reduces energy consumption.

Air quality sensors are often equipped with IoT components and use wireless protocols such as Bluetooth Low Energy (BLE) or Wi-Fi. The sensors transmit their measurements to central control systems or cloud-based platforms, where the data is analyzed to initiate automated control measures. These include activating ventilation systems when CO₂ levels rise or adjusting climate systems. Self-healing mesh networks ensure stable data transmission, even in challenging or large building structures.

The sensors are used in various types of buildings. In office buildings, they help optimize indoor climate by continuously monitoring CO₂ levels and dynamically adjusting ventilation. In residential buildings, they help minimize pollutants, regulate humidity, and efficiently manage energy usage. In public buildings, such as libraries or administrative facilities, they monitor air quality in real time and adjust air circulation based on the number of occupants to ensure comfort and health.

Integration into cloud-based platforms significantly extends the functionality of air quality sensors. These systems aggregate the initial captured data to identify long-term trends, predict maintenance needs, or discover optimization potential. Over-the-Air (OTA) updates ensure that the sensors are regularly updated to include new features and meet modern security standards.

Air quality sensors are a key technology in modern building automation. They enhance energy efficiency, improve indoor air quality, and enable flexible system adjustments to changing requirements. Through precise measurements, they make a vital contribution to sustainable, resource-efficient, and comfortable building concepts.
