Category:Sensors and Monitoring Methods

Overview

The Sensors and Monitoring Methods category addresses the operational diagnostic question: "How do we detect and measure indoor air quality?" Continuous monitoring is essential for identifying exposure peaks, but reference-grade instrumentation is prohibitively expensive and geographically sparse for dense indoor coverage.

Aligned with Work Package 3 (Task 3.1, Task 3.2) and Campaign C1, this section evaluates the applicability, accuracy, and best practices of consumer-grade and industrial low-cost sensors (LCS) alongside scientific reference equipment. It documents laboratory intercomparisons (conducted at TROPOS and IMROH facilities), sensor fusion methodologies, cross-sensitivities to humidity and temperature, and deployment protocols across European pilot cities.

Covered Topics

• Sensor Hardware & Platforms: Multi-sensor devices deployed across EDIAQI pilots (AirSensEUR, Sentinels, Thinnect, Canarin CAMI2, AirVisual Pro).
• Validation & Calibration: Procedures for sensor drift correction, environmental sensitivity testing, and laboratory calibration against reference spectrometers and gas analyzers.
• Measurement Protocols: Guidelines for sensor placement, temporal sampling intervals, and establishing Pilot City Labs as participatory observatories.
• Data Interoperability: Adherence to OGC SensorThings API standards and IoT security protocols to ensure FAIR (Findable, Accessible, Interoperable, Reusable) data sharing.
