| Real Time Air Pollution Monitoring |
| Hardware: |
4 modules including 4 different sensors, together with their signal conditioning blocks |
| |
Microcontroller |
| |
A Ni:Cd dry battery system to supply the microcontroller and the TGS modules |
| |
IBM-PC compatible |
| Software: |
Microcontroller software for data acquisition |
| |
IBM PC data acquisition software, Turbo Pascal 6.0 programing, to transfer the microcontroller data |
| |
Dedicated software (Visual Basic 6.0 medium) provides the concentration values of the detected gases as function on time. The file dimension is 100 concentration data for each of the four sensors |
| Education: |
A 10 minutes measurement session in a real environment is done. After all, the microcontroller is serially coupled to an IBM-PC and the environmental data are calculated and interpretated. |

Where Gs is the SnO2 semiconductor layer conductance at the c concentration;
G0 is the SnO2 semiconductor layer conductance at the c0 reference concentration;
K1, K2 and p are the calibration curve parameters. |
