We are working on developing an industrial refrigeration system. The RPi seemed like a good choice based on its ability to run Python and the number of I/Os. We need a fairly large number of sensors (temperature, pressure, flow) and many of these are analog.
I have been working on developing an ADC board based on the TI ADS1115. It would seem, however, that someone else may have solved this problem already. Does an input module that takes analog voltages and currents and outputs them onto I2C exist? I know that similar modules exist for PLCs (with RS232, MODBUS, etc output), but does a similar thing exist for I2C?
