Nanoenvi IAQ

Indoor Air Quality

(2)

Our time in interior spaces

We spend 90% of our time indoors, without sufficient natural light or fresh air. And it's something we no longer think about ... But science has shown that it can be detrimental to our health and our

well-being.

Indoor air can be up to five times more

polluted than outside

(3)

¿What is

Nanoenvi IAQ?

Nanoenvi ® IAQ technology allows to create wireless networks in interior spaces that transmit in real time information about the air breathed to applications that the user consults from any device.

Nanoenvi IAQ is indicated for its placement in homes, work centers, classrooms, hospitals, conference rooms, garages, laboratories, cinemas, theaters ...

With a compact and modern design, the Nanoenvi IAQ device can be easily installed in any room, either in a desktop or wall configuration, completely unnoticed.

The ENVIRA IoT solution for monitoring indoor air quality contributes to:

• Reduce interactions and multiple exposures.

• Prevent and detect possible diseases related to buildings (legionella or hypersensitivity pneumonitis).

• Reduce energy expenditure costs by carrying out a more efficient air renewal strategy.

• Avoid sick building syndrome, where most occupants suffer from allergic reactions such as sneezing, coughing, nasal, eye and throat irritation, or skin irritation.

• Reduce the impact of the symptoms of people suffering multiple chemical

hypersensitivity.

(5)

All IAQ equipment includes sensors to monitor, in real time:

• CO2

• Volatile Organic Compounds, Hydrocarbons (VOC)

• Temperature

• Humidity

• Atmospheric pressure

• Dust and particles PM1, PM2,5, PM4 and PM10

• CO

• Designed in Europe

• Manufactured in Europe

• Assembled in Europe

(7)

Reliability, stability and precision to the extent

The calibration of the sensors that

incorporates the indoor air monitoring solution is done one by one in the

ENVIRA IoT laboratories against

internationally recognized standards.

Both the calibration process to which the equipment is subjected in the laboratories, and the corrections applied, are made with the aim of offering maximum reliability and

stability in the results. All the sensors

are subjected to tests and trials so that

the final result is the most accurate and

reliable, guaranteeing an accurate and

error-free measurement.

IAQ COMMUNICATIONS

(9)

Visualization and data analysis

The data collected by the sensors are transmitted to a platform for data management, from which it is possible to receive and store the data of the sensors, the management of users and alarms and the preparation of reports.

Thanks to the analysis of indoor air quality, we achieve:

Improvement of work environments

Application of improvements in the strategy of ventilation and renewal of the air.

Reduction of the sensation of "charged air" in closed spaces.

Decreased risk of spread of diseases or infections by air.

Increase in productivity and reduction of work absenteeism in work environments.

Guarantee of a safe and healthy environment.

Atmospheric pressure sensor specifications

A miniature 5 x 3 x 1.2 mm LGA package is ideally suited for the space constrained requirements of portable electronic devices. Low current consumptions of

5 μA during Active mode and 1 μA during Shutdown (Sleep) mode are essential when focusing on low- power applications. The wide operating temperature range spans from – 40 °C to +105 °C to fit

demanding environment conditions.

The MPL115A1 employs a MEMS pressure sensor with a conditioning IC to provide accurate pressure

measurements from 50 to 115 kPa. An integrated ADC converts pressure and temperature sensor readings

to digitized outputs via a SPI port. Factory calibration data is stored internally in an on-board ROM. Utilizing

the raw sensor output and calibration data, the host microcontroller executes a compensation algorithm to

render Compensated Absolute Pressure with ±1 kPa accuracy
