The issue after you built the Chronulator is that you want to measure everything using those nice meters...
Displaying the temperature using a LM35 and a meter used as a simple voltmeter is no problem. I did it even though I have no electronics experience.
I have never found a simple way to display the hygrometry (relative humidity) though.
It would be nice: a panel with the two meters of the Chronulator, under it two other meters: temperature and relative humidity. Temperature scale could be 10 to 50 C° (indoor) and relative humidity 0 to 100% of course...
Perhaps in a future version on the same kit ?
In the meantime if someone could help me with a standalone simple relative humidity using a meter...
And by the way, what about a meter displayng the atmospheric pressure... I wish I was able to do all this by myself...
I realize that what you need is a curcuit that converts those measures to a voltage that the meter can then read.
Many thanks.
Edit:
I just found this, I believe it can be some kind of a solution...
