One way to take this to another level but is quite elaborate is to use lock-in amplification. The lock-in amplifier is a very small bandpass filter dependend on a reference frequency. If you change the reference frequency of a lock-in amplifier in a very small range around your stimulation frequency you can get really high resolution measurements with noise close to zero and even insane time resolution. This is the way you can get everything out of these setup.
Hi Shane. I just found your video and I love how you were able to do this. I am also doing something similar, but with less 4 and 4 sensors, 8 in total. Basically I want to replicate a Vehicle parking sensor. But I want to use the JSN-SR04T waterproof transducer. I have found a sketch of how to use them, but I am very new to programming and my only problem is in the stage of graphing the data ... You have been able to graph it in an interesting way, With lines that indicate the different ones. But I want to graph it in an RGB led bar, where I can see the distance by color (Green, yellow and red) and the location (left, center, right) Fluidly throughout the led strip. I would love to receive guidance and advice on how to represent the signals of the sensors in an RGB LED bar. 🙏

Could you please elaborate on this or give some lead, I am really interested in doing this. Thank you for suggesting this wonderful idea.
holy F this looks like a big sonar array in the front of those huge scary submarines

This is how the heartbeat sensor in call of duty was made😂
Thanks for sharing! sound is low, hard to hear you.
Can you please explain the arduino code?
