Air Quality in Duitama Municipality from IoT Sensor Network

Duitama, Colombia, hosts an IoT sensor network measuring air pollutants at multiple city locations. The dataset likely contains time-series readings for temperature, humidity, CO2, CO, and particulate matter (PM2.5, PM5, PM10) transmitted every 5 minutes. It was published via datos.gov.co and last updated on 2026-05-18.

Use Cases

• Modeling correlations between particulate matter (pm2_5, pm5, pm10) and meteorological variables (Temperatura, Humedad Relativa) for pollution forecasting.
• Analyzing temporal trends of carbon monoxide (co) and carbon dioxide (co2) levels using the Fecha timestamp.
• Comparing air quality readings across different sensor locations identified by the Nombre Equipo column.

Strengths

• Data is collected at a high temporal resolution, with a transmission rate of every 5 minutes.
• Includes measurements for 7 distinct air quality and meteorological variables (co, co2, pm2_5, pm5, pm10, Temperatura, Humedad Relativa).
• Sensors are deployed at multiple, specified geographic locations within Duitama, allowing for spatial analysis.

Limitations

• Metadata completeness is limited; row count, data license, and author are unknown, which may limit suitability assessment.
• Last updated 2026-05-18 17:51:44; freshness should be verified as the date is in the future relative to the current time.
• Data may reflect geographic bias inherent to the specific sensor locations in Duitama.
