  • In this IoT internet of things project, I have explained how to make an IoT based water level indicator project using NodeMCU ESP8266 Blynk and ultrasonic sensor. For the LOW water level, the pump will start automatically and you will get a Blynk notification on the smartphone through the internet. Also, you can monitor the water tank level on OLED.

    • IoT Based Water Level ...
    For this NodeMCU ESP8266 water level indicator project, you can use any ultrasonic sensor as the water level sensor in the tank. You can always monitor the tank water level on OLED and if the NodeMCU is connected to WiFi, you can monitor the water level from anywhere in the world on Blynk IoT App.
    In Manual mode, you can control the water pump manually from the switch and Blynk app.
    The alarm will ring when the tank is full and when the water level drop below the threshold limit.
    During this video, I made the circuit on zero PCB using the PCB layout, and also shared the wireless automatic water level controller circuit and source code.
    If you want you can connect a relay to the control pump, otherwise you can use this IoT Project as the water level indicator.
    During the ESP8266 project video, I covered the following topics:
    00:39 Quick demo on water level monitoring system.
    03:16 Required components for the ESP8266 IoT project.
    03:35 Circuit diagram of the IoT-based water level controller.
    04:14 How to make the water level indicator on Zero PCB.
    05:13 Set up Blynk IoT Cloud for ESP8266.
    07:44 Source code for the water level controller project.
    09:48 Set up the Blynk IoT app for the water level indicator project.
    11:40 How to connect relay buzzer with water level sensor circuit.
    Required components for the automatic pump controller.
    1) NodeMCU ESP8266
    2) SR04M waterproof ultrasonic sensor OR HC-SR04 sensor
    3) 0.96" OLED Display
    4) 1k 0.25watt Resistors - 3 no
    5) BC547 NPN Transistor
    6) LED 5mm - 2no
    7) 2-pin Push Button - 3no
    8) SPDT slider switch
    9) 220uF 25V DC Capacitor
    10) 2-pin Terminal connectors (3 no)
    11) 3-pin Terminal connectors (1 no)
    12) 5V DC Buzzer
    13) AC to DC converter HLK-5M05 5V (Optional)

    SR04M waterproof ultrasonic sensor: amzn.to/3EXi7Rp
    Important points:
    1. For the SR04M waterproof ultrasonic sensor minimum measure distance is 25cm, so the distance between the sensor and the full tank water level must be greater than 25cm.
    2. As per the logic, the ultrasonic sensor will only calculate the water level if the measured distance between the predefined values for the empty tank and full tank.
    3. Define all the distance values in cm.
    4. You can press the button to stop the buzzer.
    5. Here I have used an Active HIGH relay, so the relay will turn ON for the HIGH pulse.
    6. You can either give AC supply, or 5V DC supply as shown in the video.
    7. Please watch the complete video, otherwise you may face some issues.
    **Please take proper safety precautions while working with high voltages.
    This IoT-based ultrasonic water level sensor project will help you to maintain the water level in the overhead tank, also it is very useful to save energy and water resource.
    If you face any issues please let me know in the comment section.

      project is not good at all. i have done every thing right according to this video. problem 1: some time physical button work,most of the time it does not work but, blynk buttons are good.. problem 2: sensor giving lag result,some times water percent/distance is not changing as result pump is not working correct.

    Hi. Your project is great and very easygoing. I have tried it but I am facing an issue that during auto mode reading from the ultrasonic sensor is spiked above 100% frequently due to this running pump stops within short time. Can you implement any code by which if readings are above 100% or starting percentage for more than 2-3 seconds then only output count. Thanks you are doing a great job.

      You can set the logic that if the motor is on by automated mode and if the current water level reading and the water level reading after 3/4 minute stays the same the motor to turn off automatically I think dry motor can last for somewhere around 10/15 minutes without any significant wear and tear

    The video and content are perfect, but the audio quality is inferior.
    Bro your channel has potential, please buy a condenser microphone for voiceovers, it will sound much more professional, and trust me more people will watch it.
