Quick diagnose reversing/parking sensors with this DIY Probe.
If you need to test reversing/parking sensors a good way could be to use a sensor which can detect the waves generated by these sensors.
Understanding this concept, Bernard Hannigan has implemented a DIY probe with a 16mm Ultrasonic Wave Sensor Transmitter Receiver (cost less than 1 USD, model: TCT40-16R/T). Following are the pictures of this built.
The BNC connector plug into the oscilloscope connected to the phone with HScope. Results of the detected signals with the Automotive module are following.
