Complete your entire design in Kicad, including: |
|||
|
|||
* Circuit / schematic design: |
|||
|
|||
* Make sure to assign the appropriate values / ratings for each component. When you select components make sure they exist on a commercial electronic platform (e.g. some are listed here: https://gitea.iitdh.ac.in/PEG/PEG-Wiki/wiki/PurchasingComponents) |
|||
* Assign appropriate footprints to each component |
|||
* Make sure to run the Electrical Rule Checker before moving to the layout. |
|||
|
|||
* PCB Layout design |
|||
|
|||
When you are done, export the design as a SINGLE ZIP FILE (File > Archive) and then upload the zip file here. |

1. Question text: |
|||
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. |
|||

|||
3. Block diagram |
|||
|

4. Power supply design |

5. Industrial Design: |
|||
|
|||
6. KICAD Design |
|||
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. |
|||
|
|||
7. Pricing / BOM / Assembly |
|||
Final prixing? |
