Wiring Diagram
I think this is right.
A few points:
- Sensor power is supplied / managed via the power manager (not the esp32)
- I’m not sure if the way all my grounds are linked is optimal, but it seems to work.
- I’d suggest getting everthing except for the sensors connected and working first (including the voltage divider), and then add the sensors / pump one by one and test that they are working.
- Set a short deep sleep cycle of like 30 sec on 30 sec off etc during testing.
- I2C can be fussy and not keen on long wires. Solder at least on the sensor sides (dupont on other end ok? ).
