This project was a part of a student initiative to integrate IoT systems and AI in public parks. We installed custom sensing devices and developed an IoT platform to monitor indoor and outdoor public facilities' usages, including tennis courts and seniors room in 4 different parks at the City of Surrey. Some of the data is to be used for energy efficiency predictive analysis.


We are grateful for the Parks and Recreations department managers and workers, who generously allotted their time and efforts to work with us and help us install the sensors, as well as provided us with feedback on our reports. <\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Some conclusions for collected data over the course of 4-5 months.

                    - Parks usages in the winter month drastically decreases.

                    - Parks with outdoor facilities, such as tennis courts, are more active on weekends

                    - Even though the results were expected, quantifying the usages allows for a more accurate
\n                      reporting, rather than relying on estimations

\n\n                    - Temperature and humidity data indicate that the HVAC system was maintained within a specific
                      range, regardless of whether facilities were used or not. \n\n


Based on the findings, we made some suggestions to the department. \n
