I'm trying to visualize how you can tell percentage in or out with a reed switch, which is surely more likely to be a limit switch? Unless you can rig lots of switches and or lots of magnets to indicate a grainy position?
Do you have the actuator? Perhaps we should hear about it: how it gets controlled, how it gets powered, etc etc
Yes, I have an actuator with reed magnetic sensor, it's installed to a valve that control of water flow, it's powered 38 vdc by relays, and controlled by level of water tank, but it's still manually operated, I want to control and monitor it by my phone through wifi, so I start learn about arduino.
Should I change reed sensor to hall effect sensor so the arduino can read the stroke position? Because I searched so many tutorial on google and youtube they're all use hall effect sensor, not found yet whose use reed sensor.
Please reply. Help.
