I built a water quality monitoring device for Earth Day. My solution worked great until mother nature decided to put it to the test. I’m an embedded developer by trade and a hardware engineer by preference, so I know my way around a soldering iron.
In retrospect, my first design had a handful of mistakes you can easily learn from. There are interesting things to consider, like how to prevent water ingress using off-the-shelf enclosures, how a hot glue gun can be your best friend, how to capture/visualize sensor data remotely, how to transmit your sensor data over cellular without worrying about SIMs, and archaic modem commands, and finally how to protect yourself from catastrophic loss.
