I am looking the the .NetMF for my hobby use. I need a simple temperature sensor and that is actually pretty straight forward however I also need him to be wireless since it will be located approx. 30-40 feet from the mainboard without the possibility to connect with wires.
Been surfing the net without any luck trying to find solution to this maybe a sensor capable of connecting to a wireless transmitter with a receiver on the other end.
My project is small at first, I have a hot tub which does not have a temperature meter but I would like to monitor it’s temperature to see when it is ready. I would locate the meter either in the water itself (providing that I can make it water proof) or attached it to the outside of the hot top shell.
On the receiving end at first I would just like to get the temperature reading displayed on a screen (similar to this 4.3" https://www.ghielectronics.com/catalog/product/421) to monitor the temperature manually. Maybe in the future I would like to upload the temperature reading to a DB, web service or something similar but that is not a priority in phase one.
Then challenge I am having is finding where I can buy components to make the temperature reading wireless. I find very little documentation or components on the internet for this purpose.
Hope someone has done this before and has a solutions to this.
One would think smaller er better but it depends also on price and complexity. The idea for this is to make this a personal project, buying a mainboard similar to FEZ Raptor or Ceberus and build a solutions to monitor the temperature of the hot tub and also other meters or surveillance gear as thing progress.
