I would appreciate advice on creating an axle sensor using a Teensy 4.1 connected to a sensor.
Basically, I need to detect when a wheel of a vehicle rolls over a thin/narrow aluminum strip which is glued to the roadway and placed perpendicular to the direction of traffic. The system needs to detect when a wheel rolls over the strip. Wheels may roll over the strip every 100 ms.
I thought of a simple Piezo sensor but the ones I found would be easily destroyed by the wheels. I also tried the Adafruit 9-DOF Orientation IMU sensor but I could not get it to work.
What is the right sensor to use and a good circuit to connect to the Teensy?
Thanks in advance.
