Hey IOTinker, I found this old oak pallet in the garage—imagine turning it into a self‑watering planter with a moisture sensor and a tiny solar panel. Could be a great mix of upcycling and automation, right? What do you think?
Nice idea, but your solar panel will only push about 5W. The 12V relay and 12V pump are a mismatch. Either use a 5V MCU, a MOSFET, and a 12V to 5V buck converter, or just go with a 12V solenoid and a cheap 12V soil sensor that outputs analog voltage. Then feed that into a 10‑bit ADC, log it, and build a Grafana dashboard. Don’t forget to calibrate the moisture range with a pot. Also, don’t forget the garage door‑bell logic in the same house—those things don’t play well with public APIs.
