Water level measurement

[Chowdhury_Milon]

Hi,

I want to measure water level using Arduino UNO and ultrasonic sensor ((DYP-ME007TX-3pin), Picture attached). I saw several examples but they used LINX. I want to use Arduino option but I failed to make any VI. Any suggestion or help is appreciable.

TIA

Arduino is one of the targets of the LINX package. Was there something wrong with the examples?

What do you need help with?

I would suggest that you start by establishing communication with the Arduino, and then with the sensor via the arduino, and then try making a measurement.

Once you have a measurement, you can expand your code to process the results into a water level measurement, probably using some trial and error.

Thank you, Mr. Cbutcher

I have attached the example, my LINX option's picture and a sample VI here. Would you check and make the correction, please?

That VI appears to be the Ultrasonic Read. It's under LINX > Sensors > Distance > Ultrasonic > Read.vi

Hello, Mr. cbutcher,

My ultrasonic sensor is 3 pined. and "MakerHub > LINX > Sensors > Distance > Ultrasonic > Read" is for 4 pined sensor. I also tried the attached VI but failed to get any readings/result..... 😞 😞 😞

Hi,

So assuming that you set up your sensor (with 3 wires) like in the schematic shown on the front panel of the example you uploaded (which, by the way, just calls the VI I mentioned but with the two inputs having the same value 😉 ), can you use the Highlight Execution or a collection of Probes in the lower-level subVIs to determine where the problem is?

Hello Mr. cbutcher,

I am trying to find out the solution for 2/3 weeks. I bought 3 types of sensors but can't get any result.  Now  I am really exhausted. this is my last try. I have attached two VI and one pdf here. I have followed the instruction of pdf file but an error occurred. Would you try to find out the problem, please? 

TIA
