Amonia Sensor |

|

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. |

|||
Final prixing? |
