This is an experimental page hosting real time data from an air quality sensor in Tomang, West Jakarta, showing PM 2.5 levels.
Note that the sensor is indoors – readings usually reflect average outdoor air quality but sharp spikes are from cooking, and lows are from evenings when the doors are closed and an air filter is running.
(Note that the final graph contains some erratic readings due to a sensor malfunction in the middle of the year)
