I am still a newb so sorry if this is simple but I found if you are using serial monitor you need to make sure the speeds are the same.
If you set in code then change the serial monitor to match.
Also in 2nd picture, your capacitor is behind the feeds, wouldn't it need to be in front? Again I am just guessing as I don't really know 
Hope this helps.
I have RHT03, DS1307, BMP085, 16x2 LCD connecting to a UNO. But not fully working yet.
Sensors are nice though 
are yours good?
