Hey everyone! I'm working on a university project involving a go-kart and I need to incorporate a fuel level sensor. My professor recommended using an ultrasound sensor because I'm already utilizing a Raspberry Pi to manage the various sensors I have. I want to display the fuel level on an LCD dashboard. However, I'm facing challenges in selecting an appropriate ultrasound sensor that operates at around 3.3-5V. I initially thought of the JSN-SR04T, but the tank's height is less than its blind zone, so that won't work. As someone relatively new to electronics, I'd love any advice on whether I can utilize a higher voltage sensor, and if so, how to do it. Thanks in advance!

If you're on Amazon looking for options, search for "fuel level sensor". You'll find plenty of sizes. For around $25 to $30, there are rod-type sensors that would likely fit your needs. They’re generally pretty reliable too!
Not to sound harsh, but why go for an ultrasonic sensor for a moving vehicle? It's probably not going to give you accurate readings because it'll fluctuate with the movement. You should really dive into research and explore other sensor types that might work better for your specific application. There’s a lot out there if you put a little effort into finding it!
Honestly, for your project, it might be easier to use a fuel tank that already has the sensor built-in. But if you're looking to DIY it, a mechanical float like the type used in toilet tanks could be a solid option. You can find some sensors on Amazon that might work too. Just make sure they fit your tank dimensions!
Thanks for the sensor suggestions! I’ll check those out. 🙂
From my experience with automotive fuel systems, I have to say you might be disappointed using an ultrasonic sensor due to fuel movement. These sensors typically need the fuel to be still for accurate readings. Plus, gas can be harsh on certain materials, so make sure your setup is compatible. Try experimenting with a clear container that mimics your tank's shape and fill it with water to see how the movement affects reflection. You might find it enlightening!
I did search online and asked my professor the same thing, so no need to be rude. I was specifically recommended the ultrasonic sensor, so I was hoping to get some constructive suggestions.
