In a joint effort between the University of Washington and the esteemed intERLab research facility, a groundbreaking project is underway to monitor air quality in specific regions of Bangkok and Chiang Mai. By leveraging cutting-edge sensor devices, mounted on Grab delivery riders’ helmets, researchers aim to collect real-time data on PM 2.5 and CO2 levels. This data will provide valuable insights into the air quality experienced by riders as they navigate different areas of the city.

The sensors used in this project employ advanced technology to capture air quality information in real time. Producing data every second, these sensors are equipped with micro-SD cards to store the recorded information along with the sensors. The data can be visualized using a heat-based map, enabling researchers to observe and analyze the air quality patterns over a 1-week period. This approach allows for comprehensive data analysis and informed decision-making.

During the initial trial, certain challenges were encountered that called for improvements to the sensor devices. One such limitation arose when the sensors were exposed to rain, resulting in potential malfunctioning. To mitigate this issue, additional protection measures will be implemented to ensure the sensors remain functional even in adverse weather conditions. Additionally, feedback from riders highlighted the weight of the sensors as a potential discomfort during extended periods of use. To address this concern, researchers are exploring innovative methods to reduce the weight without compromising data accuracy or collection efficiency.

Building upon the insights gained from the initial trial, the project team has outlined a roadmap for the next phase of testing. Starting on Thursday, June 29, 2023, the bustling metropolitan region of Central Ladprao in Bangkok will be the initial focus of data collection. This vibrant area promises to provide valuable information about air quality in a dynamic urban environment. Subsequently, the team plans to visit Samyan Mitrtown during the following week, commencing on Monday, July 3, 2023. This area’s unique characteristics make it an intriguing location to assess air quality trends and potential variations.

Recognizing the significance of regional air quality assessments, Dr. Adisorn and Dr. Preechai from intERLab will also be embarking on a journey to Chiang Mai from July 10-14, 2023. This expansion will allow the researchers to gather data outside of the bustling capital and explore the air quality dynamics in a different context. The findings from Chiang Mai may provide valuable comparative insights and help identify potential patterns or disparities between the two regions.

The collaborative project between the University of Washington and intERLab presents an exciting opportunity to gain deeper insights into air quality levels in specific areas of Bangkok and Chiang Mai. With the innovative use of sensor devices mounted on Grab delivery riders’ helmets, real-time data collection becomes possible. Overcoming challenges faced during the initial trial and implementing improvements, the project is poised to yield valuable information on PM 2.5 and CO2 levels. Stay tuned for more updates on this remarkable initiative as we uncover critical data that can contribute to a healthier urban environment.
