Low energy consumption AQMS monitors
Featuring world’s premiere solar air quality monitoring station

The concept

Well known for its pioneering role with regards to sustainable innovation, ENVEA is the first manufacturer in the world offering tropical climate class air pollution monitors. Furthermore, as they can be 24V power supplied and significantly reduced energy use, the e-Series monitors have made possible the building of a complete solar powered AQMS station.
Installed since June in ENVEA’s Headquarters in Paris area, the first all-in-one and standalone AQMS monitoring station has withstand succesfully during the summer temperatures up to 50 °C without air conditioning and without connection to the power grid. Enclosing 5 air quality monitors, the solar station measures criteria gases and fine particulates 24 hours a day, 7 days a week being powered only by solar energy.
Able to be installed in isolated site, this innovation is major for air pollution monitoring networks for many countries or sites where power grids are unavailable, unstable or very random, with frequent power outages.
The reference monitoring station encloses the well-known eco-designed e-Series pollution monitors, QAL 1 certified and US-EPA approved, offering the best metrological performances on the market for the continuous monitoring of O3, NO2, SO2, CO and fine particulates PM10 or PM2.5.
The station being equipped with data acquisition & handling system, the measured parameters are automatically transmitted wirelessly to a central server for data management and overall supervision.


A forerunner in its domain, ENVEA has always played an active role in raising awareness about environmental issues. Our air quality and ambient monitoring solutions enable successful action to be taken to protect the environment and communities.
We are committed to a strategy that implements eco-design and eco-innovation. Consequently, ENVEA is the first and only manufacturer of certified and approved eco-designed air quality monitors, offering the best metrological performance on the market for the continuous monitoring of gases and particulates.
Furthemore, e-Series analyzers can be 24V power supplied and able to withstand temperatures up to 45-50°C without air conditioning and connection to the power grid.
This new and unique feature opens the way to new approaches in the air pollution monitoring techniques, with the benefit of important energy savings. Outstandingly, a full reference pollution monitoring station including ENVEA’s e-Series analyzers require only 300W·h where stations equipped with other monitors on the market require over 1300W·h. And this, for 24/7 measurement of the 5 criteria pollutants: O3, NO2, SO2, CO and PM10 / PM2.5 fine particulates.
With the ENVEA’s new low voltage analyzers, public and private authorities can measure the air quality even in isolated places with limited or unexistant power grid, and power the monitors with green energy (solar panels, wind turbine, batteries, etc.). Moreover, the analyzers are designed to be highly resistant to extreme conditions and are proved to operate at 100% of their capacity with a surrounding ambient temperature without air conditioning.
Low Energy Consumption
The e-Series power consumption is 80% less than other analyzers’ on the market.
24V Power Supply
24V Power Supply
ENVEA’s eco-designed AQMS certified monitors benefit from a unique feature: operate with a 24 Volts power supply!
Enhanced temperature range
Enhanced temperature range
Monitors able to withstand high temperatures without air conditioning and connection to the power grid.
Robust, sturdy and accurate
Robustness of products and mechanical resistance to impact. ENVEA analyzers can operate in a long-time period without any failure.


These new AQMS analyzers powered by 24 Volts and with a such low energy consumption, offer unlimited integration possibilities. 100% autonomous monitoring stations operating only with the use of green, renewable energy, to the benefit of our planet. It becomes possible to implement analyzers in areas without power grid where an operator oversees the daily replacement of batteries in the cabinet.
All of these integration examples allow our analyzers to adapt to your environment and your field constraints.

Solar AQMS is a major innovation addressing supportive government regulations for effective air pollution monitoring and control, ongoing initiatives towards the development of environment-friendly industries, increasing public-private funding for effective air pollution monitoring, rising levels of air pollution, and increasing public awareness related to the environmental and healthcare implications of air pollution.
Worldwide government agencies and academic institutes, commercial and residential users, petrochemical industry, power generation plants, pharmaceutical industry, smart city authorities, etc. are highly appreciating its numerous advantages, such as:
  • Its low consumption, its ease of integration into the landscape and its great autonomy make it an ideal instrument for sustainable cities
  • Its technical characteristics make it a profitable investment: low maintenance costs, low consumption and eco-sustainable concept
  • It opens the way to pollution monitoring in remote places as well as to developing countries indeniably marked by the lack of the electricity grid.
In order to demonstrate the feasibility of such a project, ENVEA has installed a 100% solar powered air quality monitoring station in its HQ. Please find below the real time Air Quality Index in Poissy (France) & the consumption informations of the ENVEA solar AQMS station.

Let’s not forget either the considerable energy saving potential brought by photovoltaics. Today, more than 20,000 traditional pollution measurement stations and therefore connected to an electrical network are located in the world. For example, the 670 measurement stations spread over French territory could save around 20,000 kWh / day, equivalent to an annual consumption of nearly 1500 homes.
