Compatibility with various building protocols :

The QAA (Ambient Air Quality) sensor from NanoSense stands out for its ability to adapt to a variety of building protocols, making it flexible to implement in many environments. This adaptability is crucial for integration into existing or new building management systems (BMS). Compatible protocols include EnOcean, Modbus and LoRaWAN, each offering specific advantages.

Complementary to IAQ probe EP5000 via EnOcean 

EnOcean: Wireless, battery-free communication :

  • Energy-efficient: EnOcean is a wireless, battery-free protocol, making it ideal for sustainable development applications. It uses ambient energy (such as sunlight and temperature differences) to operate, reducing maintenance requirements and battery waste.
  • Easy installation: Due to its wireless operation, EnOcean is easy to install and configure, which is particularly useful for existing buildings where wiring can be a challenge.

Modbus: Flexibility and reliability :

  • Industrial standard: Modbus is widely used in industrial and building applications for communication between electronic devices. It is known for its reliability and ease of integration.
  • Supports Wired and Wireless Communications: Modbus is available in RTU (wired) and TCP/IP (wireless) versions, offering flexibility for different building configurations.

LoRaWAN: Long range and low power consumption:

  • Ideal for Smart City applications: LoRaWAN features long range and low power consumption, making it suitable for smart city applications and buildings scattered across large campuses.
  • Security and range: LoRaWAN offers encrypted communication and can cover vast areas, including places difficult to reach with traditional wireless technologies.

Key features of the QAA probe:

  • Precise measurement: QAA measures essential parameters such as CO2, VOCs, particles, temperature and humidity, providing comprehensive air quality data.
  • Versatility: Designed to adapt to a variety of environments, the probe can be used in commercial, residential, educational and healthcare buildings.
  • Connectivity: Multi-protocol connectivity enables easy integration into existing BMS systems, optimizing air quality management and building energy performance.


The QAA probe from NanoSense, with its ability to adapt to multiple building protocols, offers a flexible and effective solution for monitoring and improving air quality in a variety of contexts. Whether in a single building or on the scale of a smart city, the QAA probe is an invaluable tool for optimal management of the indoor environment.

Interaction between indoor and outdoor air :

Indoor and outdoor air quality are intrinsically linked. The EP5000 IAQ sensor from NanoSense, designed to monitor indoor air quality, plays a crucial role in this dynamic. By comparing indoor air quality data with outdoor air quality data, it is possible to optimize ventilation operations, whether manual (such as opening windows) or automatic (via ventilation control).

Optimizing manual aeration :

Precise monitoring of indoor air quality helps identify the optimum time for manual ventilation. Opening windows is often the simplest and most direct method of improving indoor air quality. However, this action must be carefully timed, taking into account the quality of the outside air to avoid introducing additional pollutants. The EP5000 sensor helps to determine the best time to ventilate, based on pollutant levels and outside atmospheric conditions.

Automatic ventilation control :

When integrated into an automated ventilation system, the EP5000 device enables more precise control of indoor air quality. By continuously measuring levels of CO2, VOCs, particles and other parameters, the system can automatically adjust ventilation rates to maintain healthy indoor air. This automatic regulation is particularly effective in maintaining an optimal indoor environment while maximizing energy efficiency.

Synergy between indoor and outdoor surveillance:

The combination of indoor and outdoor air monitoring provides a comprehensive overview of air quality. This holistic approach enables ventilation strategies to be proactively adjusted in response to variations in air quality both inside and outside the building. This synergy not only ensures healthy indoor air, but also helps reduce the load on heating, ventilation and air-conditioning (HVAC) systems, leading to energy savings.

Conclusion: Intelligent air quality management :

Indoor air quality monitoring with NanoSense's EP5000 sensor, in conjunction with outdoor air data, offers a complete solution for optimizing ventilation operations. This intelligent air management ensures a healthy, comfortable indoor environment, while improving the energy efficiency of buildings. It's an essential approach to maintaining the right balance between air quality, occupant health and environmental sustainability.

Sensors make an essential contribution to the smart city:

In the context of Smart Cities, monitoring outdoor air quality has become a crucial element. Advanced sensors providing accurate, real-time pollution data play a key role. These data enable decision-makers, urban planners and citizens to take informed action to improve urban air quality, contributing to the creation of healthier, more sustainable environments.

Real-time air quality monitoring :

Modern sensors can measure a wide range of pollutants, such as NOx, ozone, fine particles, as well as CO2 and VOC levels. The ability to provide this data in real time is essential for smart cities, enabling immediate responsiveness to pollution peaks and more accurate urban planning.

Decision-making support for urban policies :

The information provided by air quality sensors is invaluable for political decision-making. It enables cities to implement pollution reduction strategies, such as traffic regulation, the creation of low-emission zones, and the development of green infrastructure. These data can also influence broader decisions concerning urban planning and sustainable development.

Public engagement and awareness :

The availability of air quality data encourages public involvement and awareness of environmental issues. Informed citizens can adapt their behavior, for example, by choosing greener means of transport or supporting local initiatives to improve air quality. This awareness-raising helps create a collective momentum towards healthier cities.

Integration with smart city technologies:

Air quality sensors can be integrated into the wider network of Smart City technologies, including traffic management, weather monitoring and energy management systems. This integration enables holistic analysis and management of the urban environment, maximizing the effectiveness of Smart City initiatives.

Conclusion: Towards a healthier, more sustainable urban future :

Air quality monitoring by probes in the context of Smart Cities is more than just measuring pollution; it's an essential tool for shaping the future of urban environments. By providing accurate, real-time data, these probes enable informed decisions to be made to improve public health and sustainability, making cities not only smarter, but also more liveable for all.
