NP2 Wireless Button/Switch

I'd like to add a door switch to an outdoor shed that doesn't have power.  Since I'm fairly new to Netduino, I'm not sure the parts needed to get the job done.  I obviously can wire a switch, but since the shed doesn't have power, I'd rather leave my Netduino in the house, and just have the switch wirelessly tell my Netduino when it's been opened/closed.

Can anybody give me a quick rundown of the parts I'd need on both ends to allow a wired door switch communicate with my Netduino?

Nobody?

If you need some intelligence at the remote end look at Pololu Wixels

I have a pair of these and they work quite well up to about 50 ft.

This is a well regarded long range module,

You can change the personality of the module by installing the appropriate firmware (Appendix 2: Dual Relay?)

Wow, I can't believe how cheap that amazon thing is.http://www.amazon.co...r/dp/B00JL30QQU

And that's all he should need aside from some door switch to trigger the button.

Nice find Baxter.

What about 300 ft or further?

The Ciseco XRF has a 1km max range with the supplied whip antenna (300m with chip antenna). Other models with chip antenna are of the order of 100m (max). Cheap 433 MHz modules typically have 20-100m range (mostly toward the lower end) depending upon the power, antenna and obstructions.

Reading toward the bottom of the page, that Amazon combo has Specifications:
Transfers distance: 80m (100-200m to the max for open spaces)
Receiving distance: 200m (100-200m to the max for open spaces)
and also, the battery probably costs more than the combo.

Important Note: The remote control does not include battery because of the strict customs inspection. Please prepare a "23A 12V" battery for it. We appreciate your understanding and support. 

Edit: While looking at that page, I spotted another remote control (claims 100m),
