Hello
I have a project with multiple mcu, they all comunicate via I2C, problem is that I nedd to log temperature with four of the mcu. The temperature sensor will be connected to the mcu by a 4 meters cable, I was thinking of I2C buffers for the cable and I2C sensors, problem is, the mcu only have one I2C port.
Any sugestions alternatives to a temp sensor over 4meters wire, maybe I can read it with ADC port?
