FOUL AIR has me investigating sensors that should help document a case against a defective sewerage system.
Honeywell's C7110A1010 Room Air Quality Sensor measures air quality in rooms, offices, and production bays. It should be able to detect whether we're getting foul air from sewage blowing back under our pavements and into our storm drains. I've seen mixed gas sensors used to control ventilation plants in aircraft maintenance facilities during a previous career in the Air Force. Some of those facilities were involved in spraying deicing fluid, paint removing solvents and mixing distillates. We need a device that can detect those kinds of industrial smells because the same technology displays readings in poor quality air.
Poor quality air affects several unfinished estates around Ireland. As explained by the Irish Times, residents of the Gleann Riada housing estate in County Longford have their case in front of Minister for the Environment and some top-notch consultants because authorities have been monitoring gas levels since a suspected gas explosion occurred at one of the houses in March. We don't want that in our estate, hence the air sensor as a first step.
