Media Release: New Mobile Air Quality Sensor for the Garden Route
For Immediate Release
22 July 2020
The Garden Route District Municipality procured a new ambient air quality sensor for monitoring ambient air quality. The Zephyr® is a compact and lightweight ambient air pollution sensor that accurately measures harmful gases and particle matter.
“Zephyr® sensors provide detailed air quality measurements in real-time to help identify pollution hotspots at a localised level such as busy road junctions, industrial activities and at area sources such as sewerage works, pumps station and stockpiles,” said Dr Johann Schoeman, GRDM Manager Air Quality Management. The district might procure more sensors over time to be able to easily deploy district-wide analysis and optimisation of pollution-lowering initiatives. Ambient monitoring is a legislative requirement for District and Local municipalities and one of the objectives of the Garden Route 3rd Generation Air Quality Management Plan.
Every unit is GPS enabled and can be used as a static or mobile sensor for while walking, cycling or driving.
Pollutants being measured
How it works
1. Power: Via a solar panel or DC power supply
2. Zephyr: Measures pollutants in the air in real-time
3. GSM: Built-in connection captures and sends data
4. SQL Database: Raw data is stored and calibrated
5. Upload Server: Data is authenticated and converted
6. Data access: Access and download your Zephyr data
7. MyAir: Access data via your online dashboard
8. API: Integrate data into an existing system
Every Zephyr® air quality sensor is calibrated prior to dispatch and its calibration performance is tested against reference standard analysers. Furthermore, every Zephyr® comes standard with a calibration certificate.
While the sensor is deployed, real time measurements can be accessed by the District Air Quality officers via a laptop, personal computer or cellular phone. This is extremely helpful especially when dealing with air quality complaints. Data is viewable in various formats such as excel spreadsheets, graphic formats or a dashboard. It can also be viewed as a snapshot, providing the user with an overall view of the air quality in the current location, based on USEPA Air Quality indexes. GRDM already requested Earthsense, the manufacturer of Zephyr®, to adopt the index for our local conditions and to tweak the programme for South African National Ambient Air Quality Standards.
The sensor is currently located in the Mossel Bay region where it is used as a tool to assist with an air quality complaint. The Garden Route has various air quality hot-spots, as identified in the AQMP. Therefore, the sensor will be moved around in the District to obtain the necessary air quality status of each of the hot spots. This data is essential in order to mitigate and improve the general air quality of the region.
It is also the District’s goal to expand the ambient monitoring network so that each town has its own Zephyr® to assist in achieving the GRDM Air Quality vision “To have air quality worthy of the name Garden Route”.
