I'm a developer but a total noob to IoT/electronics, please help!
I'm looking to create something I can put on the inside of my water tank to monitor the water levels remotely, a colleague has done this and suggested using a JSN SR04T waterproof transducer, along with a WeMos D1 R2.
I notice that the transducer has an operating voltage of 5V yet the D1 operates at 3.3V. Would I be better off going for an Arduino Uno instead as that operates at 5V?
The device itself won't be near a power source or network point, so I'm looking for a board I can run via solar/battery, will also need wifi, can anyone suggest some options?
Not sure if this is too hard for a first project, but looking to start with something I can actually use and benefit from.
Thanks in advance :)
