EPD Smart Lamppost Air Sensors Cease Operation
Start here
On 23 October 2026, the CKAN platform on data.gov.hk updated its dataset information, showing that the EPD has suspended the operation of smart lamppost air quality sensors since 1 February 2026. The dataset originally contained nitrogen monoxide, nitrogen dioxide and PM2.5 concentrations measured by smart lamppost sensors; after the suspension, DATA.GOV.HK provides only historical data up to 31 January 2026. The report did not mention the reason for the suspension, the number of sensors involved, or whether there are alternative monitoring arrangements. Current progress: the relevant air quality data has not been updated since February, and the platform retains only historical records from before the suspension.
