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:
