Remot-a-boat! Remote monitoring and relay switching by text

[Poey50]

Some folk may be interested in this inexpensive device based on the Arduino and a GSM Module. It lets me get a voltage readout by return text message from my house bank and start battery as well as temperature, pressure, and humidity information. I can also switch up to four relays and safely control an A/C power switch. It uses a 2G SIM card. All details including code available on GitHub.
