 The DHT22 sensor is pretty bulky - but it is cheap. Take a look at other breakout boards from Adafruit, Sparkfun, etc for
 other alternatives.

+[Sistema](http://sistemaplastics.com/) is a New Zealand company that makes plastic lunch boxes, food containers, etc.
+
+It turns out that their small *KLIP IT* containers make great cases for Arduino projects. They are relatively cheap and
+come with clips and a rubberized seal. I've not tested how weather proof they are in real conditions but they look
+really good.
+
+Their [200 ml Rectangular box #1520](http://sistemaplastics.com/products/klip-it-rectangular/200ml-rectangular2) can handle a *two* board stack and

+Add a bit of foam or something like that to hold your project in place. The plastic is easy to work with if you want to
+drill holes, etc.
