Dataset of Indoor Air Pollutants using Low-Cost Sensors

Indoor air pollutant concentration data is collected for all the seasons in Pune city, India, from internet of things-based system built using low-cost sensors. The raw data contains 1,73,468 records collected from Nov 2020 to July 2022. Air pollutant PM2.5 (Particulate Matter) is measured using GP2Y1010AU0F Dust Smoke Particle Sensor, NO2 (Nitrogen Dioxide), NH3 (Ammonia) and CO (Carbon Monoxide) pollutant measured using MICS-6814 sensor. Ozone (O3) measured using MQ131 Semiconductor Sensor. Temperature, Humidity measured using BME 280 sensor. Measurement units of NH3 is PPM, NO2 in PPM, CO in PPM, PM2.5 in ug/m3, Temperature in Celsius, Pressure in hPa, Humidity in RH, Ozone in PPB. This data can be used for study and evaluations of prediction models, low-cost sensor data and calibration. It can be used for the study of the pollutant’s patterns in COVID-19 pandemic. It will help policymakers to develop policies to monitor air pollution impact.
