    hello guys,
    if anyone want to add Gauge or Graph in the blynk for any analog or float data, then follow below instructions:
    To add Graphical chart in blynk,then you can select the superchart. For that, you need to go to blynk mobile dahsboard, then go to the blynk widget by clicking on + sign. scroll below and you will get the super chart. click on that. it will be added to your template dashboard. now click on it and in the property, you will get the datastream. we can add only 1 chart on free version. click on the sign that is lookalike music visual adjuster. once clicked, you will get the option to select datastream. select the virtual pin of
    tds value and its done. back to dashboard and you can get your values on super chart.
    Same process, you can follow for the Gauge.

    • @SMEDehradun
      @SMEDehradun  Před 2 lety +1

      You can’t directly read 2 sensor in A0 pin. So, You need to add multiplexer like CD4051 with NodeMCU so that you can read multiple analog sensor on A0 pin.

      Hi, use below code to make Ts meter with Arduino. Connect TDS sensor data pin to A0 and Vcc to 5V.
      #define TdsSensorPin A0
      #define VREF 5.0 // analog reference voltage(Volt) of the ADC
      #define SCOUNT 30 // sum of sample point
      int analogBuffer[SCOUNT]; // store the analog value in the array, read from ADC
      int analogBufferTemp[SCOUNT];
      int analogBufferIndex = 0,copyIndex = 0;
      float averageVoltage = 0,tdsValue = 0,temperature = 25;
      void setup()
      {
      Serial.begin(9600);
      pinMode(TdsSensorPin,INPUT);
      }
      void loop()
      {
      static unsigned long analogSampleTimepoint = millis();
      if(millis()-analogSampleTimepoint > 40U) //every 40 milliseconds,read the analog value from the ADC
      {
      analogSampleTimepoint = millis();
      analogBuffer[analogBufferIndex] = analogRead(TdsSensorPin); //read the analog value and store into the buffer
      analogBufferIndex++;
      if(analogBufferIndex == SCOUNT)
      analogBufferIndex = 0;
      }
      static unsigned long printTimepoint = millis();
      if(millis()-printTimepoint > 800U)
      {
      printTimepoint = millis();
      for(copyIndex=0;copyIndex 0)
      bTemp = bTab[(iFilterLen - 1) / 2];
      else
      bTemp = (bTab[iFilterLen / 2] + bTab[iFilterLen / 2 - 1]) / 2;

  • @nurulnajihabintiabdulsamad2081

    Sir, at the end of the video, shows that we need to connect the USB cable to nuttyfi and connect it to the computer's USB right. So why do we need to that? or it is because we want to power up the nuttyfi?
    After this,, if we want to check the temp. or pH again, do we need to connect the sensor to the coding or we can just only use the blynk apps? and how to check it? do we need to connect it with the coding again?

    • @SMEDehradun
      @SMEDehradun  Před rokem

      We use the usb for 2 purpose basically- one for uploading the program & another is to provide power. Right.
      And once we upload the program to out any board, then that program stored in the memory of that board. We don’t need to upload it again and again. Once program uploading done, then just provide the power to your board and it will work all the time as per your code.

    Good day sir. I already done making with this project with the use of NodeMCU I'm glad it really works. Is it possibly sir that after I stored the program in NodeMCU it can directly connect to the wifi network of Blynk?. When I stored the program and did not use a computer to run the program again it can't connect to the WiFi network Blynk. Thanks for response

    • @SMEDehradun
      @SMEDehradun  Před 2 lety +1

      Once you upload the program to NodeMCU, it’s permanently stored it in NodeMCU. Once you power the NodeMCU, it will be automatically connect to blynk. If not, then there can be power problem in your circuit. Verify your connection & program again.

      Hi Rahul,
      Connect the NodeMCU with the similar pins as shown with NuttyFi board in the video. Connections are the same for NodeMCU & NuttyFi.

    I completed this project sir.Still I have to add few modules like:
    1)widget to display the quality(good,fair,poor)
    2) turn on led(demonstrate that water purifier is on if tds is high)
    3) gmail alert if tds is high

      Hi,
      That’s great that you have done your project 👏.
      You can display the TDS level or quality, then you can use virtual LCD display to display it. This video will help you setup the virtual lcd in the blynk IoT app.

      And if you want to add email alert then I have already made a video on how to set email alert. Below is the link to guide you.

      Check that you have selected the board as NodeMCU as described in the video.
      It will work.

    • @SMEDehradun
      @SMEDehradun  Před 2 lety +1

      This problem occur while we have not selected the appropriate board or some time new blynk library not supported due to old blynk library.
      I suggest, you once again see the video, follow all the instruction, install blynk library once again.
      And run our code without changes.
      It must work.
      If still problem will remain, then comment, then we will check your code.

    But in earlier version we used to put in code in the form of SSID and pasward
    And keep changing in code if our WiFi networks is changing like WiFi router to mobile hotspot
