Topic: [Solved] HC SR04 interfacing with DUE? (Read 2067 times) previous topic - next topic

Hello

I was wondering if the HC SR04 ultrasonic distance sensor is compatible with the DUE because the output signal of the HC SR04  is a 100us 5v pulse, will the DUE refuse the input? I am a bit hesitant to test it and was wondering if someone has done this.

Thanks.

You could use a voltage divider ...

a 10k and 15k resistor (where they meet) should give a 3v signal as a high...

Good idea, I'll test it today using a voltage divider and test using a pnp transistor an see whether is works.

Hello everyone

I have verified that the the HC SR04 ultrasonic distance sensor is compatible with the DUE. As cjdelphi suggested a voltage divider of 5.6K and 10K solved the 5V interfacing issue.

hello. I have the same problem that you've had. I have to interface the sensor HC-SR04 with arduino DUE and I thought well I use transistor and a voltage divider. I used a transistor bc558c only that it is giving vcc gnd that the base always gives me 5v output. transistor that you've used? so what do you recommend I purchase on the safe without spending money to try several. Thank you!
