I don't need sensors. Sensors are metal pieces to put in tankI do not think it is possible to build the LCD part or the ultrasonic sensor yourself so there is no point in having the schematic of those items. You could build the Arduino uno yourself but it would cost more for the parts than buying it ready made. This is a link to the Arduino schematic if you do want to build it yourself. The link in post #2 even provides the code which is as bonus as you only requested the circuit diagram.
If you have sensors you are going to have to specify what they are.I don't need sensors. Sensors are metal pieces to put in tank
I need a circuit diagram for wireless 4 water tank levels indicator. 4 pieces of steel metal rod 6mm is used for sensors tied to wires are inserted in the tank at different levels,which is input for transmitter and receiver LED displays the levels of available water in the tank. I am buying it from the market and want to make it. Their PCB is filled with epoxy. Range required is 15-20 mts.If you have sensors you are going to have to specify what they are.
Really, if you want help, you’ll need to start over with a better description and information about what you already have. It’s just a guessing game at this point. This forum isn’t a form of google filter, or shouldn’t be.
Not sure what you mean. The capacitors and diodes are necessary to pass and rectify the AC signal injected from Q1. The AC signal is important to reduce the electrolytic erosion of the electrodes that would occur if you just us pulsing DC....Only better cut the U1 inputs let halve the input current (unused may hang over Vcc). And diodes are completely unnecessary as well the 0.1m caps - water have ~10 kOhm per cm thus those are oversecuring. ...
