Awesome project. I was thinking about building something similar, but without the weather station, for some local lakes. Have you thought about having it transmit sensor data live, e.g. via LoRaWAN?Also, do you have any more details on the type of sensors in use?

I've been wanting to do stuff with concrete for quite a while, thanks for putting this back up towards the top of my list. One thing I've seen to make them look more unique was to dip them partly in paint, so one half is still concrete coloured. Also some adhesive plastic feet are nice to not damage the surface you put them on.One question: you put a hole for drainage in them, do you have anything you put underneath them for catching that water?
