Design Summary (add text in the box below or upload a PDF)
Explain how you approach this design problem.
Include your assumptions, trade-offs, with any and all design choices you make.

View File

Upload the block diagram of the system you have designed as a single PDF.
Hand drawn diagram is acceptable - just make sure it is neat and clearly labelled. Mark all interfaces. Make sure to include suitable power supply/supplies.

Name
1. Question text:
CO sensor
2. Design summary:
Very well written. Low Battery detection / alert is especially well done
3. Block diagram
Where is the block diagram?
you have given the entire electrical circuit diagram here.
Only some logical / hierarchical block diagram was needed here.
4. Power supply design
There are two major probems with your design.
a. The 9V battery you have chosen is not exactly good for long life. Look at other products that need long life batteries -
all use some kind of non-rechargeable lithium cells.
b. You are using a linear regulator which has expremely poor efficiency - you're going from 9V to 5V!
Should have used a 6V battery and LDO.
Microcontroller - pick one with low power consumption and/or sleep modes like the MSP430 or AtTiny.
5. Industrial Design:
Summary is fine - should have included sketches of the final unit. Where should the LED be? Where are the mountings for
buzzer / speaker?
6. KICAD Design
Schematic:
No major issues seen
PCB:
Layout could be a little better - you have many traces intersecting / overlapping.
Especially look at the sensor heater supply - those traces could be thicker.
What is the current needed there?
7. Pricing / BOM / Assembly
Some BOM optimisation could have been done - mostly all ok
Price for 2 prototypes not mentiones?

1. Question text:
Design a system using the humidity sensor (https://drive.google.com/file/d/10Z0jvXlMJBG0_FohJ6fIrFQnS-VmN8HF/view?usp=sharing) to detect when relative humidity (RH) in a room goes outside the "normal" range of 30%-60%. When RH is outside the "normal" range, a buzzer should sound The device is intended for a controlled-environment room that contains several rare medicinal plants.
Any long term (more than a 2 hours) deviations in humidity will kill the plants causing losses of at least 100,000$. A facilty manager is supposed to turn on a humidifer or de-humidifier as required when alerted by this device.
2. Design summary:
Could have added more details.
Adding temp is a good idea, but what about the original problem of reliability / fail safe?
3. Block diagram
A uC cannot drive the buzzer directly normally,
The block diagram should have much more details, at least at a high level.
Also signal types, levels, widths, etc.
4. Power supply design
None submitted
5. Industrial Design:
6. KICAD Design
