So I bought 3 caperplus pH EC meters (before I realized how stupid that was). It’s a cheap Chinese wifi meter and the servers for the app are Chinese and don’t work in North America (that’s my guess as to why the app doesn’t work), so I’m interested to see if I can’t get some Arduino code with preexisting libraries to work on it.
I’ve got 3 and I don’t need any, so if any experienced programmer wants to help I can loan you one. It would be a nice alternative to the atlas products and that expensive shield. You can buy a caperplus wifi smart meter on aliexpress for about $60.
This meter uses an esp8266mod, and I’m guessing it has the optical isolator, and ADC, as well as a display. I’ll include some pics.
So where would you start with this? I tried to solder a USB serial programmer and destroyed the debugging leads, so my next attempt is to use a 3d printed pogo pin adapter and the serial programmer. But that’s just a first step, IDK where to go from there, I’m too new to all of this. I would just give up and sell them, I’ve got all the other Arduino parts I need without these, but I’m in this to learn.
