12 Ultrasonic Sensor with NodeMCU and Blynk App

[@Naoo3198]

After I tried and successfully compiled and I look at the blynk display with the widget I see only the gauge is active and the lcd is not active even though I have followed the file you made, please advise how?

i use esp32, the code works well but the distance seems not working. cause it stays in 0.93 cm even i approach it to near paper. someone can help me with that?

[@fathimatuzzahrakhoiriyah]

and in my blynk doesn't change at all, stay 0 :(

Same happens to me. It stays on 1 Cm in my blynk app and in the Arduino IDE output

I'm trying to transfer the distance I get from hc-sr04 sensors to thingspeak using Nodemcu. Only when measuring distance the sensors work very well but when I write the code to transfer the data to thingspeak or firebase the sensors work very slowly. What could be the reason for this? how can i fix it
