My intention when buying it was to cut the cable connecting the sensor to the display and instead connect the sensor wires directly to my Arduino Uno. First, I wanted to figure out the relationship between the signal output and the measurement shown on the scale. Then, I planned to write code to convert the received signal into the corresponding measurement in millimeters.
Well, the sensor arrived a few days ago, and since then, I’ve been trying different approaches—but without success. I’ve tested multiple communication protocols, and they all yield the same result: whenever I move the scale, the signal detected in the Serial Monitor doesn’t change, as if the sensor weren’t connected (even though it works perfectly when connected to the original display).
I’m considering buying some adapters to interface between the sensor and the Arduino (such as a USB Host Shield or RS422, for example) to test with those, as I suspect the communication protocol used by this sensor might not be compatible with my Arduino.
However, before deciding whether to purchase them, I thought I’d ask here in the forum to see if anyone could help me with this issue.
That’s it... Thanks for your attention, and I wish you all a good day!
