Node MCU + HC-SR04 ( Ultrasonic sensor ) did not work with 3.3V !!!

This video is about using HC-SR04 with NODEMCU
Not working , HC-SR04 5V is required
NodeMCU output 3.3V only

You can use a 5V power supply but at ECHO pin it is recommended to use a voltage divider or logic level shifter to safely read the voltage for the pin. It also works well with me in raspberry pi.

[@raspberrypibuenosaires]

you need a Voltage Translator/Level Shifter like KY-051, then you will get the Ky-050(HC-SR04) working, this will converte the 5V in 3.3V so the nodeMCU will can read it

[@zakiemochamad5254]

You can use VV pin for your Hc sr04 power supply

[@ANTHONYBOOTH]

I can't see how this did not damage the Node MCU; - the ultrasonic module puts out 5v signal.... - so surely it would damage the MCU...

[@iamhemanthsai2035]

Thank you bro, ultimately we need to give to 5v from 8266 VV and or from arduino 5v ❤❤

[@PhysicsWallahMotivation]

Help, I want to connect a battery and ultrasonic sensor both in nodemcu. But only one VIN pin available, how can I connect both ... Can I connect battery + terminal in 3v as input.?

[@dlopeza]

If you are usb power, you can use the VU pin (5v from USB)

[@luismakluf]

Thanks info.

[@jimjulian4443]

In case no mentioned, the HC-SR04P will work with 3.3V.

Nice video but please dont forget the Big muachhhh at the end next time. ;)

What program are you using for circuit diagram at 0:40 ?

[@samratvlogs6170]

can you plase tell me the connections of all the pins

[@abdullahmujahid6851]

use 3.3 to 5v bidirectional level converter

[@MakerVerse]

No, it's not that it doesn't work on 3.3. Actually does work if you manually remove the 3.3vcc and plug it again in the same pin WHILE it is running.
The problem only happens in the Arduino startup, when it is first launched it will not work but if you do what I said, you will see it works on 3.3v.
Now I'm trying to figured out someway to make it work without manually doing that... D:

[@farukozgur6514]

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

[@sauravmehtaUnique]

I just made my project working by attaching the Vcc pin of ultrasonic sensor with Vin pin of NodeMCU.

[@neerajkashyap01]

Thanks for the comment Saurav.

[@prajwalgujarkar593]

Is it really works??🤔🤔

[@sauravmehtaUnique]

@@prajwalgujarkar593 Yes it did work but was not very accurate

[@alovelyboy1]

it works thanks

[@iamhemanthsai2035]

Ultimately we need to give five words from esp8266 VV or 5 volts from arduino UNO 3.3 volts not supporting by ultrasonic (mine)

[@adamfiqrie8350]

Hello im new for arduino.... Upload code to arduino board or esp 8266 in arduino ide?

[@MKA_NET]

It doesn't look like it can be connected directly. Can someone please recommend an ultrasonic sensor that can be connected directly AND that's fully supported by ESPHome?

[@rohail4007]

Esp32 sy VIN ma bhe lag skty tha

[@rizqisubhan8683]

Can NodeMCU be used with two ultrasonic sensors?

[@MattGithens]

Yes, they wouldn't even know about each other. You could run 4 ultrasonic sensors on one NodeMCU - even more if you were to get crafty with the trigger pins (parallel firing) on the ultrasonic sensors.

[@kashifthemaker3945]

HOW IS THIS A SOLUTION?

[@senger1985]

Hello,
can someone tell me why my sensor jumps over 100 and back again
I have a external 5v Powersuply, for my sensor.

[@UBsLab]

It has malfunctioned. Needs to be changed

[@MuthuKumar-bz1ly]

use Vin pin in nodemcu it will be solve....

[@zakiemochamad5254]

Not VIN pin but VV pin

NO YOU NO NEED EXTRA ARDENO i CAN RUN CODE WITH NODE MCU 8266

[@rememberme5334]

My desktop shows max distance

[@CuddleStories]

Isn't the Node MCU 3.3v logic? The signal from the ECHO would burn it.

[@jusalpukat520]

SUDAH DILAKUKAN CARA ANDA MASIH GAGAL KENAPA YA

[@Tyty-qe4yr]

for me it says 400cm forever

[@UBsLab]

Needs to be replaced

[@mosesidiong5060]

Me too

[@UBsLab]

These sensors do not last for more than a month or two. They are pretty cheap.
