COVID-19 AoT Air Quality Change Report, Chicago

Jan 13, 2021· * Because all of the 2020 and PM10 data come from the Ashburn sensor, city-level aggregated estimates for and PM10 are suppressed. Figure 1 shows trends in air quality over several weeks with the most recent data representing approximately 1-2 days ago-this is how long it takes AoT to publish real-time air quality data.

Evaluation of Low-Cost Sensors for Ambient Monitoring

Low-cost sensors are an opportunity to improve the spatial and temporal resolution of particulate matter data. However, such sensors should be calibrated under conditions close to the final ones before any monitoring actions. The paper presents the results of a collocated comparison of four models of low-cost optical sensors with a TEOM 1400a analyser.

Sensors - Smart Cities PRO Sensor Guide

This sensor has a very high cross-sensitivity with NO2 gas. So, the output in ambients with NO2 will be a mix of O3 and NO2. A simple way to correct this effect is to subtract NO2 concentration from O3 concentration with an NO2 gas sensor. The measure from the NO2 sensor must be accurate in order to subtract the right value.
