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 falls below 30%. When this happens, an exhaust fan needs to be turned on. The device is intended for small controlled-environment chamber. If humidity falls too low it means ventilation is inadequate, and a fan needs to be turned on. The fan is a 230V 50Hz fan. Your device needs to be as small and compact as possible so as to not take up space in the chamber. + +2. Design summary: + + >> I have taken the output of the sensor, passed it to the opamp with +ve of the opamp at 1860 mv. Then I have passed that output to BJT which connects a. c. to the fan.

What are signal widths, voltage levels, etc? +Where are the interface specifications? + Why is there a transformer and also a buck converter in your design? + +4.
