Here we will tell you How to Make Wireless water level indicators at home. We will build a wireless water level indicator using Arduino and an ultrasonic module in this project. The ultrasonic sensor is used to detect the range of the object from it. The ultrasonic sensor detects the presence of an object based on its distance from the module, which we can configure through various properties of the sensor.
This circuit can control the water pump up at the roof top, where we don't have any electrical wire. And when it rains, it's very difficult to go on the roof and connect the wire with the pump to make necessary connections. So by using this wireless water pump controller, we can easily manage our home watering as per our needs. In this project, we will build a wireless water level indicator with the pump on/off. This project can help you monitor the water level of your water tank or any other liquid in your tank. To do this, we will use a float sensor and an LCD, which displays the amount of liquid inside the tank.
Introduction: Automatic Water Level Controller Without Ultrasonic Sensor
To give the Sensing connection in the Overhead Tank, initially decide the levels at which the pump has to switch ON and switch OFF. As usual procedure, ON Level can be 50% of tank capacity and OFF Level can be 2 to 3 inches less than 100% capacity of Tank . As the source of water is Bore well, the sump sensing function have to be bypassed in the controller itself. To bypass the sump sensing function, Yellow wire, Black wire, Green wire and Red wire have to be just shorted and insulated with Insulation tape. The sensing wires comprises of two bunches of wires, one bunch of four wires for sump or lower tank and another bunch of six wires for upper tank. Do complete sensing wiring from Water Level Controller to Overhead Tank and Water Level Controller to Underground Sump / Well.
In this article the white wire is connected to the pin 4 on the arduino, green wire to the pin 3 and brown wire to the Vin. This circuit will detect the water level, and once it reaches the low level it enables the motor pump, and when the water reaches the higher level the motor pump stops. The concept of single phase electrical meter or single phase energy meter. After watching this video you can make the connection of electr... You said the circuit is working smoothly, so is it working smoothly with short wires?
How To Make Automatic Water Level Controller
Connect two wires from “OFF BUTTON SERIES CON.” of Level Controller to the two terminal of OFF button in series, i.e. Identify the Power Terminal Block with sticker of connection details in Water Level Controller. You'll have to connect the Jumper wires to the board. Connection of a 380V three-phase motor on 220v single-phase.
Make the loop of the sensing wire, as to hang the sensing arrangement to the top portion of the tank with the help of a hook or nail. Fix the grey portion of the wire to the top of the PVC pipe with insulation tape as with the regular insulation tape. Cut the pipe about 2 inch less than the height of the tank so that pipe can be hanged vertically inside the tank. A LDR sensor is designed with a IC 741 opamp and changed thoroughly such that the light falling over the LDR continues the pin3 of the IC low in accordance with a targeted light source and with use with pin2 set voltage.

However this would have made the lower left gate output high, switching ON the LED marked OK, but due to the diode 1N4148 it keeps its output low so that the "OK" LED remains OFF. Now suppose, the level of the water falls below point "B", the positive from point"C" is inhibited and this point now goes logic low via the 10M resistor . However if the upper reset switch is pressed, the latch is reversed and maintained to negative, switching OFF the horn.
This means, whenever main tank needs to be filled up and pump protect is false, this gate turns on transistor Q3 which will turn on the water pump. In addition to what was shown in the slide show, this control circuit includes two LEDs, one green LED to show when pump is running and a red LED to show when control is in pump protect mode. The green LED comes on every time the relay comes on.
Now short the two delay wires and insert it inside the sleeve firmly. This will introduce a 15 second delay for all ON operation. Repeat the steps from STEP 2 to STEP 5 for four to five times to ensure the correct operations.
When water touches pin7 to pin1, all the output pins from pin10 to pin16 will turn zero volt, and the transistor relay circuit will be switched OFF. I have a water level sensor which gives me an output of 0-190ohm. You can even manually connect a 0V or ground supply to the base of BC547 and you will find the latch instant breaks. However this latch will quickly get restored through the 10K supply unless the 10K/100K junction is held at zero volts which is implemented by the pin#10 while pin#7 is immersed in water. Yes you are right about the water resistance.
The diagram shown in the video is slightly different than the one shown in the article. Please follow the diagram which is shown in the video since it is much easy to build. The probes indicated with ground ends must be connected with the ground line of the circuit. Now suppose the water level falls below point A, the upper two gates reverts their position switching OFF the LED marked HIGH. Assuming the water content to be at point A, the positive potential from point "C" in the tank reaches the input of N1 through water, making the output of N2 go high.
The contacts of this Power relay are rated at 40A 300Vac. This is more than enough for pumps up to 1HP at this voltage. The sensor wires may be striped to a length of around 1 inch and fixed using two-compound glue inside a PVC pipe. The position of the sensor wire ends and the length of the pipe will depend on the size and the depth of the tank. Immerse all three UG sump sensing probes inside the UG sump water.
This new Connection stop the supply of (+) voltage to the relay "C" but In the Circuit the higher relay is still off and within the relay the connection is same as previously described. So, the relay "C" gets the (+) voltage supply to operate and as a result, the relay is still on and the motor is still running. The circuit run smoothly when water lower the pin 7 of ic the motor run automatically and when water touched at pin 1 the Relay stop and the motor also stopped. Now when the water started decreasing below pin1 the relay start chattering and this caused the relay burned.
The terminal connectors used come with a sliding lip on one side and a groove on the other. Here’s how to make your own water level using nothing more than a length of flexible, plastic tubing and two stakes or dowels. As long as there are no outside influences at work , the water at one end of the body of water is the same height as the water at the other end. A water level simply substitutes a plastic tube for the body of water. Now immerse Pump OFF sensor also inside the water, now pump should switch OFF immediately. This can be done by immersing and lifting of the sensor arrangement in the OH Tank water.

I am not 100% sure on just what to change to make the operation opposite from what it is. I want the pump to start when the water level is high and shut off when it is low. Install 2N3904 NPN transistors into Q1 and Q3 positions making sure all terminals go into their corresponding holes. Attach the clip-on heat sink before soldering each lead with the right amount of solder and wait at least 20 to 30 seconds before moving to next lead of same device.
