You dont Need to Strip the voltage Regulator from the board. Just use the marked solder pad to feed the board with 3.3. This works fine for me.

Hi,

no problem at all. The humidity scetch is running fine with a pure atmega328p-pu and a DHT11.

I have build it on a breadboard for you to see if it is working:

As you see, the sensor starts and sends temperature and humidity value:

sensor started, id 99
send: 99-99-0-0 s=255,c=0,t=17,pt=0,l=5,st=ok:1.4.1
send: 99-99-0-0 s=255,c=3,t=6,pt=1,l=1,st=ok:0
read: 0-0-99 s=255,c=3,t=6,pt=0,l=2:M

send: 99-99-0-0 s=255,c=3,t=11,pt=0,l=8,st=ok:Humidity
send: 99-99-0-0 s=255,c=3,t=12,pt=0,l=3,st=ok:1.0
send: 99-99-0-0 s=0,c=0,t=7,pt=0,l=5,st=ok:1.4.1
read: 99-1-0 s=0,c=0,t=7,pt=0,l=5:1.4.1
send: 99-99-0-0 s=1,c=0,t=6,pt=0,l=5,st=ok:1.4.1
read: 99-1-0 s=1,c=0,t=6,pt=0,l=5:1.4.1
send: 99-99-0-0 s=255,c=3,t=0,pt=1,l=1,st=ok:62
read: 99-1-0 s=255,c=3,t=0,pt=1,l=1:62

Normally I am using a DHT22 on my selfmade board.

Hi all,

the forcast is working as expected for a while now. It follows the pressure values from the device.

First diagram shows pressure and forcast. Looks like the calculation is ok.
But the weather doesnt know anything about the forecast :) 100% Humidity because it rains Dogs and Cats :)

This is no question. Just a little reminder about crystalballs :)
