I purchased the two products in the title to acquire 0-10V analog signals from illuminance sensors.
I have tried with various libraries but I cannot get the system to work properly;
I have to acquire data at least at 10 Hz with 16 bit resolution; I wired the 4 signals and made a bridge with GND. With sensors “covered” (signal about 0, checked with a tester) only channel 1 remains constant at 18 (number from 0 to 32767), the other channels increase over time. For example, channel 2, always measuring a voltage of 0.002V from 138 goes to 142 in about 20 minutes. The unconnected probes carry a signal of about 0.023V. Can anyone help me the wiring is correct, the sketch is right?
I am attaching photos and sketches.
