  • Techies and Geeks

    Are there any Techies/Geeks out there that love integrating technology and gardening?

    Perhaps a special thread might be of use.

    My current projects are
    1) An on going radio up link from my greenhouse to my house network.
    A small transmitter in the greenhouse sleeps for 60 seconds, wakes up and reads the temperature probe the sends it over radio to a receiver in the house. Being asleep most of the time it uses very little power and runs on 3 AA batteries.

    2) In the house I have a receiver that receives the radio data and sends it via USB to a small Linux server. This logs the temp to disk and provides a small web server to read the current temp and provide a graph from any day.

    3) For some while I have a heated propagator tray. Unfortunately it's not temperature controlled. So on sunny days it over heats.
    I have purchase a STC-1000 controller from ebay ( you can get them for under a tenner from China) but I use a supplier from Birmingham to get a quick delivery.
    Currently in progress with wiring it up.

    Anyone else ????

          Hi Jimmy.

          I'm not techie enough to build my own so I bought a ready-made solution instead. I wanted one that did wi-fi so I ended up with one from Corintech. Here's the exploration thread:

            Regarding point 1, what is the range of your transmitter?

            My greenhouse is 500m as the crow flies (650m walking) away from the 'puter in the house... is this expecting too much?!

              My GH is about 20m away.
              I had problems with the receiver in the house. I was using a small wire aerial.
              However I built a Yagi Aerial from coat hangers and pointed it out the window at the GH. No problems now. A Yagi is like a TV aerial with different spacing on the elements.

              My current TX/RX is AM. I have a pair of FM TX/RX but not tried them. Supposed to have more range.

              Try looking at the modules on rfsolutions web site.

                If it costs more than £10, it's too much...
