Hello everyone,
Currently right now I am investigating a project where I will use my arduino micro. to measure the water level in a 40 cm^3 grad. cylinder.
I am trying to keep the design as simple as possible, however cost is not an issue.
I need to be able to detect when the water level is at 5 cm^3 and then again at 35 cm^3.
My idea currently is to use two transistors with the gate and the emitter extending down to the specified level, and then have the collector connected to the arduino, therefore when the water shorts the gate and the emitter the transistor will go high.
However, right now I have not a clue on what type of transistor or if this idea will even work at all. Any input would be greatly appreciated.
PS. I am curious to know if measure the water level can be measured continually is that is at all possible.
Thank you.
