I'm a newbie here and would really appreciate all kinds of suggestions and answers from the experts here.
I am trying to make a small grey water recycling system project, and for the my primary filtration process tank, I will be using a combination of Metal Sieve and Cloth filter medium. The problem is, I will be making the system alert the user when filters are in need of changing and maintenance.
I made a quick sketch of my idea on paint, and as you can see, I am planning to make my grey water collection tank to look that way.
I am thinking of using pressure sensor to sense the change of weight in the sieve and cloth part of the tank for a minimum amount of time so that the system will not confuse water flow weight vs. the weight of the debris on the metal sieve, but I'm thinking that the pressure sensor is not waterproof.
I'm also thinking of like the laser module, and when the light breaks at certain level, meaning there is too much debris that has to be removed. I also googled load cells or weight sensors, but I'm really sorry I'm new to this, I don't know what is the best sensor to use for my problem.
I'm thinking of a float switch a few inches on top of my metal sieve and cloth and when it does not go on a OFF state for a certain amount if time, then the sieve is clogged, but my tank could overflow..
I need something that, when the sieve is clogged, the tank will no longer accept grey water input to avoid overflow. It has to be submersible in water too :'(
Is there a type of sensor that is most suitable for my problem?
Thank you so much everyone. Have a nice day.
