is there any sensor that can measure distances up to 500m or greater? Point the device on the object and measure the distance, kind of like the hrc204 ultrasonic sensor, but with greater distance?
ToF sensors can measure ~40 meters, however 1/2 km is going to be impossible.
NASA uses a laser . . .
Sure there is.
Google 'range finder' for examples, lots of them out there, lasers typically.

yeah I googled it but didnt find a laser with that much range
edit: I mean a laser sensor for arduino

GPS.
Get coordinates of the object of interest, then get your coordinates and you can calculate how far away you are. Accurate within a few meters so easily <1%.

i want it in real time. Like I said in the original question, I want something that works like the hrc204, but can find grater distances
the trick would be in aiming the sensor. rangefinders are based on looking through them. the next aggravation is angle measurement. rangefinders rely on line these two dots up in one place, measure the angle and calculate accordingly. the angle at 500 m would be very small, and you would need many bits to achieve any precision.
Are you looking to buy such a device or to make such a device?

So you are after an ultrasonic sensor that has a range of 500m+ ?
Are you prepared to reveal the actual applicaton ?

And describe the object you wish to detect/measure from. Is it reflective of any energy form? Light, radio waves(radar), or what? If not reflective, then the only option is use of the binocular optical angle measuring and using math to find the height of the resulting triangle(distance).

Many golf and hunting laser range finders work at your 500m distance.

Why would the sensors in the commercially available devices not work in the Arduino?

not an ultrasonic sensor, i just wanted to describe what i wanted. They are for a scope, meausring the distance between what you look at and you

well i dunno i am new to arduino

What is the Arduino going to be doing?
If you want to interface your laser module to an Arduino, look for a laser module with Serial output.
As long as a sensor has a digital interface chances are you can get it to work with an Arduino.
Post the datasheet of your desired sensor and we'll have a look.
LIDAR being used for autonomous auto driving.
Such as the Livox Horizon or Tele-15.
Hummm, I'd like on of those Velodyne solid state LIDAR's

i want there to be a screen where the distance is displayed.

lidar was what i found at first but I was wondering if there are any cheaper sensors

If there was, you might expect them to be easy to find, lots of published Arduino projects etc.
