1. Question text:
|
|
iHumidity Sensor / plants
|
|
|
|
2. Design summary:
|
|
Overall is ok- needs more details of how each component integrates.
|
|
For example the idea of switching off the buzzer by the attending person is good - how is it implemented?
|
|
That should have been shown in the block diagram!

4. Power supply design
|
|
Your power supply design assumes 2mA of sensor current but that is not necessarily the case.
|
|
Your supply is basically open loop and any change in batery voltage will cause change in sensor supply!
|
|
|
|
5. Industrial Design:
|
|
Not detailed enough!
|
|
|
|
6. KICAD Design
|
|
Schematic:
|
|
Diode D1 is backwards - your design will never get power.
|
|
The Opamp is conneced to a unipolar supply - it will not be able to sink current to drive the buzzer!
|
|
|
|
PCB:
|
|
Layout looks good.
|
|
|

7. Pricing / BOM / Assembly
|
|
Your bom sheet has a "risk rate" number. What is that?
