I am working on a project where I am trying to hook up 4 probes (EC, DO, pH, and temperature) to an arduino to help my hydroponic garden which is located in my neighboring greenhouse. Now I want these results to be able to be sent directly to my phone/ computer, for remote monitoring. While I have wifi in my house, I noticed that my wifi signal is super weak in my greenhouse. I was originally going to buy the Arduino Yun but I am thinking it may be better the buy the UNO and then attach a wifi and/or bluetooth connector to it. I am new to Arduinos and I would love any help!
