UTS has conducted research to explore the performance of the TULIP Environmental Monitoring System (EMS) under controlled laboratory conditions, alongside a number of other commercially available devices in the same class.

All three of the device types deployed at scale for the TULIP project in Lake Macquarie were assessed at UTS by a team from the Faculty of Engineering and IT, in collaboration with the Faculty of Science. An additional three air quality monitors that were not deployed for the project were also benchmarked to provide insight into comparative performance of the EMS. Using a custom-designed chamber to control environmental variables, the quality of data from each device was directly compared to data from a high-performance reference monitor. Device performance was also compared between devices allowing them to be ranked.
Three devices deployed at scale for the project (TULIP EMS; Netvox R712; DecentLab Temperature Sensor) were found to perform to a satisfactory or high standard across all parameters. This independent assessment supports their use in the project as devices that produce reliable and trusted data. The EMS performed best in its class for particulates and NO2, when compared to three other air quality monitors. It could not be compared to a CO or O3 monitor.
Test chamber design
A test chamber was constructed using the design for a Continuous Mass Flow Reactor (CMFR) to enable introduction and thorough mixing of pollutants before emissions sampling, ensuring that reference monitors and IoT devices sampled precisely the same concentrations. The chamber had an interior volume of 308 litres and was lined with stainless steel to minimise chemical interference from chamber walls.
Research Aims and outcomes:
1) Confirm that devices deployed for the project are fit for purpose
2) Determine how project devices perform against common commercially available competitors
