hello community,

my ping-sensor fell down today and it seems it hit exactly one capacitor, which is broken now. is there a way to replace that part without having to buy a completely new sensor? i've looked for a pcb / schematics but without success. i uploaded an image so you can see what happened, maybe somebody can help me out here... the red circled thing is obviously broken, it looked like the part in the green circle, if that helps.

    It looks like a standard 0805 cap. I had one fall of an ebay ultrasonic, never found it :/. Anyways remove it using a solder wick/braid. Test the size with a meter that does caps, the cap must be removed first! Then order a cap the same size in an 0805 package from digikey/mouser.

    Hopefully someone knows that caps value, but if not the above method may work.

    Problem is, the cap is fallen of, so nothing there to measure anymore. Any other ideas to find out what capacitor I need?
