Currently, expensive static curb side sensors costing £40K-£50K are used to measure NO2 and PM2.5µ particulates.
These installations use laboratory grade Chemiluminescent analysers that need to operate in stable temperature controlled enclosure and require an air conditioner. They also need to be maintained and calibrated every month with calibration gas at sub-optimal levels, at a typical cost of £10K / Year.
These installations cannot provide a clear picture of the problem over wider areas and do not provide an accurate measurement of real conditions where humans walk.
Measuring urban air quality at STREET LEVEL where humans walk, and breathe requires multiple sensors and frequent readings.
A single EnviroSense unit can record up to 5000 readings per day and is small enough (~ 140 x 50 x 40mm) to be mounted on moving public vehicles (busses, taxis, couriers) as well as in static locations. This enables reliable, accurate readings to be accessed on an easy-to-use dashboard with access to LIVE data as well as historical records. Power consumption is ~1.5W in operation.
