If the initial prototypes meet the end user needs, and if there is interest in this design, PCB fabrication could be done to make the final board look professional, To view or add a comment, sign in The scarcity is mainly due to the wastage of the water. In view of this, Bluetooth module based Water Level Monitoring system is an innovative idea that will inform the users about the level of liquid and will prevent it from overflowing. . LEDs will be monitoring the water level in the tank and the functionality of each LED is explained below : Presently, as the water ascends the sensors begin to get in contact with the water and the transistors are activated and there is a progression of current in the transistors making the LEDs light up. Hey! A more elegant solution that provides a programming interface would let the end user build different solutions of his/her choice. The second resistor (R2 - 22,000 ohms) acts as a pull down resistor and prevents input pin D4 from floating. And also to design a contactless water level indicator and controller using ultrasonic sensor with DRY PUMP RUN PROTECTION. if Pump running and Sump tank empty then Pump will stopped. I looked at a few products available on Amazon that detect water level and turn off the motor/pump (there are different variants that work with single phase motors and 3 phase motors). Now, that weve collected all the components lets assemble them and design the circuit. percentage=(ActualReading/WaterLevelMAX*100); else if(percentage>20 && percentage<=100), if(percentage>20 && percentage<=100 && flag ==1), else if(percentage>20 && percentage<=100 && flag ==0), https://drive.google.com/file/d/11egiPu2fzW4Sn2ypX6yYpG9r5-iuY-TP/view?usp=sharing, https://drive.google.com/file/d/1_5t3tVkQNHQk60k0gRRFQR1lUCjvaC1z/view?usp=sharing. Manual/auto/off modes. Some of the alternatives that were considered and dropped: I built two boards with the Mk2 design and they are being tested by two colleagues at their respective houses. If Water level below 20% then Pump will start Running and. This problem can be tackled in an electronic way. Right, so the usage of carbon based electrodes instead of the generally available steel electrodes was to avoid rusting. My colleague stays in an independent house and has a water tank on the terrace. As we are using 5 digital pins in input mode, this circuit requires 5 pull down resistors. This caused the voltage to drop below the threshold for logic level HIGH for the digital pin and it would always read logic level LOW (0). // put your main code here, to run repeatedly: Water Quality Monitoring and Notification System, Christmas Tree Water Level via Cayenne and MKR1000. Finally, we will install the device into the tank. We decided to build a solution that does not require wires between the probes and the controller. #define MOTORPIN 8 // Arduino pin tied to Relaypin of the Relay Circuit, #define BUZZER 9 // Arduino pin tied to +ve terminal of the Buzzer, float TankHeight, WaterLevelMAX, GapbwSonar, SonarReading, ActualReading, Temp. In any case, everybody who has a water tank above knows the sort of issues that they face. Maximum sensor distance is rated at 400-500cm. In such cases, the design has to be changed and alternate transmit/receive modules that provide wireless connectivity in 2.4Ghz band or the ISM band have to be used. LEDs light up from Red to Yellow and then Green and finally Blue, thus making a sound. We have successfully installed the device and it is indicating the water level in the tank. Once salt was added to water, the conductivity would go up (and resistance would down) and the voltage drop was not significant. This project monitors the water level and emails alerts. We possibly need to make two channels so when they are in contact with water they will go about as a switch, as water is a good conductor of electricity. This means we can use a threshold of our choice (based on the purity of water in an area) and the system would still work. When the P2 probe was dropped into the mug with water, the green LED lit up validating this design. To view or add a comment, sign in, Great write up Kishor, by the way great solve too.hope you can turn this to a commercial product, Awesome, man. I decided to build a microcontroller based solution that detects and transmits the water level to a cloud hosted database. The Node MCU board can also be stripped down further and could be powered by a battery, but we did not venture in that direction as power supply was available on the terrace. The analog pin read gave values between 265 to 300 indicating an input probe voltage of ~1V. Buzzer, this is used to notify when the sump tank is empty. Once enough water is pumped up, the motor has to be switched off manually. It observes the level of water and provides the information to the registered users through wireless. There is a need to control the water wastage to save the environment and water resources. We discussed about having a smart sensor hooked to a programmable switch that can turn on/off the motor. There is a total of 7 transistors and they will be sensing the water level.
It works on the principle of echolocation. When we start the water pump water starts to get pumped from the underground water reservoir to the overhead tank. In the tank, there is a set of sensors and they act like a switch. I am Hamza. This was a bit puzzling at first and after ruling out possibilities like soldering issues etc he was able to get to the root cause of the issue. NewPing sonar(TRIGGER_PIN, ECHO_PIN, MAX_DISTANCE); float TankHeight, WaterLevelMAX, GapbwSonar, SonarReading, ActualReading, Temp; lcd.begin(20, 4); // set up the LCD's number of columns and rows: pinMode(MOTORPIN, OUTPUT);// Relay pin as output pin, digitalWrite(MOTORPIN, LOW); //Turn off the relay, pinMode(BUZZER, OUTPUT);// Buzzer pin as output pin, digitalWrite(BUZZER, LOW); //Turn off the Buzzer, WaterLevelMAX=0.9*TankHeight; // 10CM GAP BETWEEN MAX WATER LEVEL TO SONAR FIX. Water is pumped into the overhead tank from a ground level water sump using an electric motor. All the householders are storing the water in overhead tanks by using the motor pumps. Tank water level monitored in Android Mobile using app. If the input probe is connected to the A0 pin, we would get the voltage as an integer between 0 and 1023. Fundamentally, the unit is comprised of different sensors going about as a switch. It works very long life.
The water level monitoring system is a automatic process to detect and indicate the level of water in the reservoirs, overhead tank or any other storage containers, etc. When you have a 'real' Christmas tree, it is important to keep it watered. It is this value that will enable us calibrate the tank.Here introduced a push button, this is used to measure the Tank height at the time of installation of this Circuit. Easy to install. You are quite an inspiration, Great Kishor. Stick the buzzer behind the PCB board and also fix the power supply by taking care of the transformer. This unit will display the Water Level in percentage, Pump status, tank Height and Sump tank status.. If Water level above 100% then Pump will stopped. A few months back I had a discussion with a colleague about the need for a water level sensor for his house. I decided to give this a shot and see if I can come up with a solution. Interface for Serial Communication, 5pcs 3V~5V IIC I2C Logic Level Converter Module Bi-Directional Sensor Module for Arduino with Pins, 15 Ir Infrared Obstacle Avoidance Sensor, E18, D80Nk, PiBOX India Raspberry Pi 4 Heatsink, 3 Pieces Raspberry Pi Aluminum Heatsinks with Thermal Conductive Adhesive Tape for Raspberry Pi 4B Model B 3 Pieces, Embedded Kart TCS230 TCS3200 Color Recognition Sensor Detector Module for MCU Arduino. I selected the CD74HC4067 16 channel multiplexer (for it's relatively low cost and the reasonably good switching speed). Lets move on to the designing part in which we will first design the circuit and then do the conversion from A/C 240V to the regulated 5V for operating the circuit. Fix that loop of wire with nuts and bolts in that PVC pipe and afterward add a common wire to the casing. #define MAX_DISTANCE 500 // Maximum sensor distance is rated at 400-500cm. As P2 and P3 are immersed in water, we should get a non-zero voltage reading at P2 and P3, and zero voltage at P4. (A high resistance between GND and D4 grounds residual voltage without grounding the signal from P2). How To Detect Rainfall Using Rain Sensor? Manual mode: (motor pump will be constantly On). The idea is to connect two probes to two digital pins of the Arduino, one set to output mode and the other to input mode. We will screw the two L hooks to the device and fix it into the wall and afterward take A/C 220V from any socket and give it to the board. Samsung Breaks Barriers Implements Notebook Level Water Cooling Solution in the, Maximum Content Processes To Be Increased From 4 To 8 in Firefox 66 To Solve, How to Automate Your Sprinkler Control to Detect Weather conditions Through. Once the design was validated with an Arduino board, the next step was to use a board with WiFi capability and send the water levels to a cloud hosted database. The Atmega 328p or similar micro controllers do not have built in WiFi, so, we decided to stick with the Node MCU and add a Multiplexer/Demultiplexer. Yet another very useful utility for day to day life. Subsequently the Mk2 prototype was tested in Trivandrum and was able to detect water level without the need for mixing salt. #include
