I am building an Exhaust Fan system for Hospital which has 9 fans
These Fans has to be run on temperature and timer.
Fan 1 needs to be run on 26 C and off at 28 C
And has to be run like 3 minutes on and 1 minute off
Like wise 8 other fans.
Purpose of this it to have pleasent envoiroment within covid ward.
but these timings need to be change depending on Ambient envoiroment. Hospital staff could change temperatures, but I am looking for easy to use menu to do it.
I google it and found many menus but it’s too complicated and most of them dont explain storing of values: like if user selected on at 28 and off at 26 C then how to store it.
If someone has already done something like this, then would appriciate if could share.
My initial idea is to use push button rotary encorder to keep user interface simple.
This menu would be hookup ongoing coding of my project which includes millis for timer control and DS18B20 sensor for temperature control
Project is kind of rush type.
