i am doing something similar with a small water tank and going to try capacitive sensing with a micro but i dont have a circuit diagram or code yet. does this have to be with a micro? and is this school work type stuff? if not what is the application? (is it actually water)
one last question is this a real project as in do you need to build it or just sim it?
depending on tank size you might be able to use one those ultra sonice distance units, do a search on the site there is a similar project a while back.
Link to the the sensors you bought? Mine is just stainless steel wires or rods. The circuit and program flow in the link in my post #6 above is exactly what your asking for. The electronics are the same for a tea cup or a 10,000 liter tank, only the length of the sensor is different.its been my long dream to build this but budget limit on building big high concrete tank. the idea is like this. 2 sensors (assume normally LO if no water) to activate deactivate water pump on the ground. 1 sensor (SENS1) = full (pump stop if HI got water), 1 sensor (SENS2) = need refill positioned somewhere in the middle (pump ON if LO aka no water) think hysterisis. i bought the sensors in ebay china long time ago, plenty of variety there, but since i have no tank, hence no project only dream. the code is simple as ABC, pseudo...
do {
if (SENS1 == HI) motor = OFF;
else if (SENS2 == LO) motor = ON;
};
ps: darn its hard to key in TAB in this editor

man $300++ for that? arduino+lcd+ultrasonic sensor? now thats arduinophoolery i can buy a decent DSO with that. buy all the stuffs from ebay if you can find one single seller you should pay alot less... i think.this project is great and can fulfill hardware+software control, but the price is quite expensive. Any others similar project but with lower cost ?
