Air quality monitoring in museums for the preservation of works of art

Home » Air quality monitoring in museums for the preservation of works of art

Museums, archives, art galleries and libraries are spaces that require a preventive strategy for the preservation of works of art and cultural goods. ENVIRA IoT has designed a solution that monitors the quality of the air in museums and buildings with historic relevance and thus protects the works of art against mold, color fading or corrosion.

The quality of the indoor air in the exhibition rooms must be monitored so that factors such as temperature, humidity or ventilation do not deteriorate the works of art. The solution developed can help the managers of the museum to make the best decisions about the number of air changes per hour or the flow of ventilation, taking into account human comfort and the nature and state of preservation of the material exhibited.

The solution for the preventive maintenance includes:

1)  A network of wireless sensors.

2) A smart computer system for the exploitation of the data captured to generate warnings and notifications for events that may involve a risk.

Continuous monitoring

ENVIRA IoT has developed a smart monitoring system to monitor air quality indoors. This solution reports the presence of hazardous agents in the rooms of the museum in real time and, based on the data registered, strategies can be established to improve both the comfort of workers and visitors in cultural buildings and the preservation of the works of art and cultural goods.

The monitoring system developed includes sensors for:

The monitoring system developed includes sensors for:

  • CO2
  • CO
  • VOC (volatile compounds)
  • PM particles 1, 2.5. 4 and 10)
  • Temperature.
  • Relative humidity.
  • Pressure
  • Level of noise.

The microprocessor sends the data to a server in the cloud at planned intervals, its communication being through Wifi and the MQTT protocol.

Reliability, stability and accuracy in monitoring

The calibration of sensors included in the solution for monitoring in museums is conducted manually, one by one, at ENVIRA IoT laboratory with internationally acknowledged standards.

Both the calibration process of the equipment at the laboratory and the corrections applied are conducted with the purpose of offering maximum reliability and stability in the results. All the sensors are subjected to tests so that the final result is the most accurate and reliable, a guarantee of an accurate and mistake-free monitoring.

Communication modules

Actualmente tenemos homologadas en ENVIRA IoT las siguientes tecnologías:

Data display and analysis

The data collected by the sensors are transmitted to the Envira DS platform for handling data, where you can, receive and store data from the sensors in the local database or in the cloud, manage the users and warnings and draw reports

The analysis of air quality in the exhibition rooms and the storerooms of museums and cultural buildings gives as a result:

  • The preservation of the collections in the best conditions possible.
  • Avoiding corrosion and the appearance of mold.
  • Reducing the pollution agents.
  • Creating an indoor climate that is constant and controlled all the year.
  • A comfortable climate for the public.
  • An efficient energy system.
  • Analyzing how the number of visitors influences the air quality of the exhibition rooms.
  • Defining strategies for the preventive preservation of art collections and cultural goods.
  • Making decisions about the number of air changes per hour or the flow of ventilation n museums.

Warning systems

The warnings to the users can be sent by SMS (additional hardware is needed, or else a subscription to a messaging service) or by e-mail.

The solution for monitoring museums, archives, art galleries and libraries can set up warnings according to the pollutants and critical factors in the works of art to be preserved.

Advantages

Open solution, integrable with external developments at any level (device, connectivity, CLOUD or user application).

An unlimited number of devices can be included in future extensions.

High-reliable and available data in real time.

Tailored system.

Creation of data history.
