2. Design summary:
|
|
Fairly well written.
|
|
Your worst case design is ok.
|
|
Could have added a calibration step / method to calibrate at known gas conc.
|
|
What happens if there is a problem with the sensor? The clean air level
|
|
should fall below 2mV and that should trigger a different warning/alarm also.

Schematic:
|
|
Circuit design is ok overall. Could have added more functionality
|
|
|
|
PCB:
|
|
Layout is too loose.
|
|
Transformer need not be board mounted - too much weight.
|
|
If all your components are SMD layout could be tighter.
