Hydroponic 3D Printed Tower
Modular Hydroponics System
Okay so I have a question maybe someone can answer , the difference is measured between A0 and A1 , is possible to reduce the amount of pins used if using multiple leds ? with each led using two Analog ports each the ports get used up quickly, maybe someone knows a way to use less ports for multiple leds?.
I have a few of questions,if someone could answer...1.Is this for a pressurized system or can i measure "open air" with this sensor?2.Is there a ramp up time for the sensor before readings are accurate?3.Does the sensor need to be calibrated or is it calibrated out of the box?
