I am interested in setting up some sensors to automate and monitor my irrigation system.
I am looking to utilize a moisture sensor, temperature sensor, 12V water solenoid valve, flow meter and have it run off a single uno with a non-poe ethernet sheild.
I am looking at using this passive poe injector kit just for the simplicity of running one cable for approximately 90 feet. https://www.bc-robotics.com/shop/passive-poe-injector-kit/
My question is if I supply 9V through the injector to the power jack on the arduino. Run my valve off of the VIN pin, am I still able to utilize the 5V on the UNO for the other sensors as they all require only 5V?
Thank you for your time.
