That breadboard really does look very neat . I should seriously start working on my breadboard technique (which would benefit from buying proper wire as a start).

Out of curiosity: I normally see a 10kΩ pullup on the DHT11's data line, any particular reason you went with less than that?

Hi,

I am curious. You're powering the board with only 3.7 volts. The MPM3610 Step Down Converter specifications indicate an input range between 4.5V and 21V. Have you noticed any problems in your tests?
