A year or so ago loaded the Bosch iNVH app Android app on to my phone (from Google PlayStore) I never really tested out properly but to day I was checking out a parking sensor system. I have the Pico Parking Sensor detector but after doing the repair I tried using the Bosch app on my phone.
Parking sensor work the ultra sound range around 40,000 hz the mobile phone microphone works on up to 20,000hz so I wasn't expecting it to work but it did. The results weren't as clear cut as using a scope and the Pico Ultra sound micro phone but the display on the phone showed activity right at end of the 20,000hz range.



(1) Install app ---- works on most Android phones but won't work on Amazon Fire Tablets
(2) Run app
(3) In "Noise" tab select "FFT v Time "
(4) Bring phone micro phone up to parking sensor --- you have to have the microphone on the phone right up close to the sensor or use an external mike.

That's a nice little bit of tech right there. I wonder if you could use a cord in the headphone jack

Yes it works with either the built in phone microphone or a lapel mike.
