Puerto del Rosario Installs Air Quality Monitor in Los Hornos de El Charco

The City Council installs and activates this sensor in the El Charco Tourism Office, which will spend a few months in calibration before offering real‑time, publicly accessible air‑quality data.

The Puerto del Rosario City Council has installed an air‑quality monitor in the Tourism Office of Los Hornos de El Charco as part of its effort to strengthen environmental sustainability and provide useful information to residents and visitors.

The device, located very close to the Las Salinas thermal power plant (El Charco power station), joins existing stations in the area and is capable of collecting real‑time data on suspended particles (PM1, PM2.5 and PM10), pollutant gases and other environmental indicators.

During the first month after installation, the equipment will remain in a calibration phase to fine‑tune and verify measurement accuracy. Once this period ends, the data will be made public via municipal information screens and the official tourism website discoverpuerto.es.

Data recorded and sensor operation

The monitor measures gases such as carbon dioxide (CO₂), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and sulfur dioxide (SO₂); it records suspended particles (PM1, PM2.5 and PM10) and meteorological parameters including temperature, relative humidity and atmospheric pressure. An integrated anemometer also determines wind speed and direction.

It operates autonomously on solar power with backup batteries, transmits data in real time through 2G/3G/4G networks, and sends the information to a cloud platform for visualization, analysis and remote configuration. The unit features an IP65‑rated housing and complies with European and EPA technical specifications for environmental monitoring equipment.

Commitment to health and environmental protection

“With this investment, the Puerto del Rosario City Council strengthens its environmental monitoring capabilities, reaffirming its commitment to public policies aimed at protecting health and the environment,” said Mayor David de Vera.

“This measure is part of a broader urban sustainability strategy, where information and technology play a fundamental role in building a healthier, more conscious and resilient municipality in the face of climate‑change challenges,” added Public Health Councilor Rosa Rodríguez.
