Water Level Monitoring with Ultrasonic Sensor A02YYUW, ESP32, & Blynk

[@DIYYourz]

The sound quality is good. Thank you for the video

[@codervicky]

This one is the best waterproof and most reliable sensor till date.

[@ElectroniClinic]

Yes, you are right. This is my fav one.

[@PhG1961]

Great video! Very well explained!

[@joels7605]

Excellent video. I want one but I'm too lazy to make one. You should sell these.

I have a question power supply you used as external switching power supply or battery to supply your board?

[@ivanarakistainmarkina385]

I need just one measurement per day but need it battery powered. I could take ESP32 to deep sleep the rest of the time and power down the ultrasonic sensor. Could you share code for this?

[@ninouing]

Thanks for the interesting video. After all your tests, would you recommend the A02YYUW for measuring the water level within a 1000L water tank? is the wider detect angle going to be a problem with reflection from the side or the device is stable enough to be able to only detect the water level?

[@ElectroniClinic]

Ya,, this is the best sensor. Just confirm the detection angle.

One question ultrasonic sensor uses speed of sound to calculate level of water.. but speed of sound changes with temperature and humidity.. I mean during summer temperature reaches 45⁰C to 50⁰C and humidity is also high( inside tank condition) and during winter temperature reaches below 20⁰C and humidity is also low.. So how you are compensating this error?? As far as I know speed of sound changes drastically with temperature..

Water pump should turn off Automatically when water label is 100%,not manually
