Evaluation of low-cost sensors

Tropos - Mira Poehlker

The "Evaluation of Low-Cost Sensors" campaign focuses on the performance evaluation of consumer-grade sensors. Recent advancements in low-cost compact environmental sensors have enabled researchers, community groups, students, and citizen scientists to deploy these devices for ubiquitous and time-resolved Indoor Air Quality (IAQ) monitoring. Despite their great potential, these low-cost sensors are still under development, with limited information available about their data quality, accuracy, and best practices for usage.

The campaign will concentrate on a comprehensive performance evaluation of various consumer-grade multi- and single-parameter sensors in detecting pollutants such as particulate matter (PM2.5, PM10), CO2, NOX, TVOCs, temperature, and relative humidity (RH). This evaluation will be conducted in a controlled laboratory chamber using reference instrumentation at TROPOS and IMROH.

Long-term Objectives
  • To segregate commercially available low-cost sensors/air quality monitors based on different criteria (e.g., cost, accuracy, ease of use, applicability for long-term indoor measurements, maintenance costs/interval, etc.).
  • To characterise low-cost instrument intervariability and sensitivity to different environmental factors (e.g., temperature, RH variations).
  • To provide recommendations for end-users on which commercially available low-cost sensors/air quality monitors are the most suitable for IAQ monitoring.
