hello everyone,
I am planning to make a water dispenser. This is supported by an automatic switch off mechanism. Switching it on is not a problem but i don't know how to switch it off. I am a beginner in electronics and don't have much idea. However i don't want to use devices that float in the cup/bottle by which i can turn it off. I want some other sensors by which i can detect the water level of cups/bottles of different sizes and turn it off. So cannot attach any thing to the bottle also. i plan do it for only one type of liquid and i will highly encourage if someone can help me do it for different liquids also. I am making this so that it can help me in daily life also. I wish to design it by myself. Can somebody help me how do i continue to work on my project.
Note: i had planned to use photoelectric sensors. I thought of throwing a beam of light via a laser on the liquid and then catch the beam of light via the sensors and by this i can detect the level of water. But the problem is that the result is inconsistent for different sizes of bottles (also for different liquids).
Doubt: i am thinking of using position sensors at the corners (of the place below the tap to that at the extreme bottom) by which i can calculate the exact position of the liquid and by using several of them i can calculate the approximate volume and then pour the liquid of that quantity.
Here is a rough sketch of the plan that i have made using position sensors
there as an attachment-note: i will use anyone between the tap an button).
Please help me with my project as soon as possible.
Looking forward for your valuable remarks.
