Hi there,
newbie here - I have a NanoPi NEO Plus2 and would like to wire some (3 or 4) moisture sensor (model YL-69, with HC-38 modules) and then a 4-relay module. I have seen a few similar projects but my questions are:
Thanks!
newbie here - I have a NanoPi NEO Plus2 and would like to wire some (3 or 4) moisture sensor (model YL-69, with HC-38 modules) and then a 4-relay module. I have seen a few similar projects but my questions are:
- will I be able to read AO (analog output) from these sensors?
- do I have enough pins on the headers to control 4 relays and receive input from the sensors, or I need some expansion?
Thanks!
