For quite a while I had been longing to measure the waterlevel in my well.

The first attempt with a HC-SR04 failed due to distance (4 meter deep well) and problems of how to mount it in the well. Then I came across the JSN-SR04 sensor. It’s all running on an esp2866 (I found it to have better wifi than the esp32). Several parts re-used from old projects. Added small solar panel to keep it all self contained. Data is sent to homeassistant (mqtt) and a bit of log/debug data to syslog.

Due to circumstances had it been lying on my desk quite a while, but finally, today I was able to install it!
I screwed a drainpipe cap to the lid of the well and mounted the sensor in another. A simple pipe connector in between works like a charm.

    This is so fascinating. My background is in industrial automation (but not in a useful way, I have never built anything with my own hands) and there are a few projects I want to do around the house.

    Planning using what I’m used to will result in something stupid expensive and involve me risking electrocuting myself. It’s really cool to see what is possible using consumer products nowadays. Data nerds rejoice 🤓
