If you want to test the signal from the sensors you could experiment with audio software.
Below is the waveform I got by plugging a sensor into the mic socket of the laptop & driving the car. I used some freebie software called wavepad. You could probably record to an mp3 device & transfer it to your PC.
I’ve never got past the initial testing of it as I haven’t needed it, but it should show any problems with the sensors/sensor rings.
В общем, речь о подключении провода с датчика в микрофонный вход ноутбука и изучении вида сигнала.
Кто-нибудь так пробовал?
