I have not had a chance to use my DHT11 yet. It did arrive in perfect condition though. This review is more for Virtuabotix's advertising and item descriptions. I would buy this product again just because of how awesome the packaging labels are. These are some truly creative people. I can't wait to buy more of their products so I can see what else they have come up with.
They included a picture of an Arduino with lines drawn directly to the pins that work with their demo library. They also explain what each line is. This is much nicer than some of the radio shack parts I've bought that only have a product number on them. The sensor feels well constructed, and has the added plus of actually looking like a sensor.
Ok it is sitting in a breadboard now so I must go. Buy it!
Update 3/30/2012 (a few days later)
Well, I have bad news...
This thing worked perfectly and did exactly what I needed it to. That means I'm going to have to buy a bunch more to finish my grand project. Fortunately they are cheap so I won't go any more bankrupt than I already am.
The sensor was very easy to set up. Three wires and I was ready to go. They recommend using a 5k resistor but I wasn't entirely sure from reading the diagram where it was supposed to go (I'm still learning the reading diagrams part of things).
In my testing it reported the same temp as the digital thermometer I had sitting next to it. It reports the temp to quite a few significant digits (i.e. 75.1230548 or so). It is sensitive enough that it reported a temp and humidity change just from me breathing on it once.
The Library that came with the product is well written and easy to understand. I had the demo sketch up and running in just a few minutes (I used an Adruino Uno). Actually, the only problem I remotely had in the entire process is that the serial monitor I was using wasn't supporting unicode so the Celsius and Fahrenheit symbols were coming out scrambled. I just swapped them out in the code (very easy to find the right place) and put in the full words instead.
