Using K3502 parking radar as input device to microcontroller

Kits Automotive projects

Hi,
the K3502 manual says at the beginning: “Use as parking aid, or as ‘eyes’ for robot projects”.

Now, if I want to use it in such a way, as input for some microcontroller device, what would be the right point to get the proximity signal from? I suspect this would be somewhere near the buzzer, but I would like to get a constant niveau (no matter low or high) all the time the K3502 detects an object.

Also it would be nice to know which voltage is at that point and which load would it drive.
Many thanks!

The buzzer is fed a +12V signal (see diagram)
The easiest way would be to use an opto-coupler, to avoid ground problems.
