EPSRC Core Equipment Grant: Advanced IAQ monitor and remote air quality sensing system

Advanced indoor air quality monitoring kit
This advanced indoor air quality (IAQ) monitor allows simultaneous and instantaneous measurement of key indoor air pollutants (TVOCs, formaldehyde, PM2.5, PM10, ozone, carbon monoxide, nitrogen dioxide), ventilation rates (carbon dioxide) and pollution pathways (differential pressure). The high-quality monitor can be used for both walk through surveys or long-term trend datalogging (hours/days/weeks), providing enhanced capacity for IAQ research projects, industry facing air quality or building performance evaluations and for validation of low-cost air quality sensors. The equipment provides a more cost-effective and efficient method of measuring multiple pollutants in real-time, significantly reducing the time required for analysis.

Indoor Air Quality Kit (using open source platform)
ESRU currently use an open source platform (OpenEnergyMonitor) for remote monitoring of batteries, thermal stores, heating use and indoor environmental quality (temp, RH) in buildings. Funding was acquired to develop an IAQ monitoring system using the same platform to monitor specific pollutants, including TVOCs, CO, PM2.5 and PM10. The system will be fully open-source and the hardware will be based on the Arduino and Raspberry Pi platforms. Funding was requested to purchase a suite of components, including displays, PCBs, power banks, enclosures and open source air quality sensors (such as Purple Air), to develop an air quality monitoring system that can be combined with existing energy and/or environmental quality kits. The open source software will provide the opportunity to create a unique monitoring solution that can respond to emerging research needs. The kit can be enhanced periodically to address any technical issues, improve functionality, and increase monitoring capacity.
