Using ultrasonic sensor HC-SR04 with Jetson TX2

[Prabha8295]

I am working with Jetson TX2 for a project that requires the use of an ultrasonic sensor HC-SR04 to measure distance between the jetson and the detected object. But I am unable find how to connect HC-SR04 to jetson directly and achieve the distance measurement!

Can someone help me with this problem?

Have a check what interface for this device first. And googling the TX2 pin map.

Thank you @ShaneCCC. I found out that Ultrasonic sensor needs a pulse input which, to the best of my knowledge, is not possible from Jetson. This however can be achieved with the help of a Micro-controller (Arduino, Raspberry PI etc).

Looks like can connect to Nano via GPIO pin. Have a reference to below relative topic.

Using HC-SR04 ultrasonic sensor with Jetson Nano?

Hello there, I try to use the HC-SR04 ultrasonic sensor with the 40-pin GPIO extension header on the Jetson Nano. I didn’t find any guides at the internet, so because I’m a complete beginner with pins and co., I would be glad about any kind of help! So for those who don’t know: this is the HC-SR04 ultrasonic sensor, originally build for Arduino: [image] It has four pins: VCC (for power 5V), GND (Ground), Trig and Echo (for signals). So first: How do I connect it? I have female to female jum…
