Air quality monitors were installed in the University area of Stuttgart, and some analyses were made with the collected data.
The current weather data is already online and can be found at

2. Objective of the study
•
•
•
To repair, install and bring into operation three different Air
Quality Monitoring Instruments
At the existing Measurement Station in Lauchäcker, Vaihingen
And to set up the online data transfer system to IFK

Build 1996
Instrument had to be tested
and showed problems
FI blown due to current leak
Power supply board
replaced at HLUG
UV Lamp power went down
in testing phase
Replaced at IFK, from the
spare parts instrument

Build 2003
Donation of HLUG
Was calibrated when picked
up for zero point, span and
calibration settings

Had to be changed twice
Donation of UBA
Only digital output was available
Analog output was installed with
help of HLUG
Battery died out, settings lost
Replaced by Thermo Instrument
Output wasn‘t potential free
Separation Amplifier was installed

Teamviewer is a
propreitary software which
have two basic
functionalities:
1. Online file transfer
2. Remote PC control

22. Conclusions
•
•
•
•
•
The ambient air quality monitors were repaired and installed
Brought into operation with data acquisition
Results from pollution and meteorological parameters put
together for analysis
Further work could be done after the instruments are
calibrated and operating continuously
Data transfer and plotting can be automated, and the results
can be made available on the institute website [Campus Wetter
(Stuttgart-Vaihingen)]
