Plant moisture detector uses a Raspberry Pi Pico for a low-cost, easy to implement project – the 3D-printed enclosure is an added bonus

Spencer Organ recently went to the virtual Preston Raspberry Jam which had a gardening theme to talk about his project – a Raspberry Pi Pico watering can. You can see the innards above. Costing under £15, the project helps to monitor a single plant (in Spencer’s case a Sweetpea plant) and tell you the soil moisture level. The level is displayed  as a nice graph on a cheap SSD and the whole thing is powered by a Raspberry Pi Pico. A 3D-printed enclosure in the shape of a watering can keeps the whole thing tidy.

You can find details, including how to reproduce it, on Spencer’s Maker Cupboard blog.
