How to create a custom input with calibration using ADS1115 ADC and Gravity analog pH and EC sensors?

At present I have some EC and pH sensors (not from Atlas Scientific) that I’ve connected to an ADC (ADS1115) and it is possible to manipulate scaling constants and conversion equations by hand to obtain calibrated outputs. However, I’m hoping to create a custom input to compute/derive EC or pH readings from the ADC reading. These sensors have to be calibrated and I am hoping to somehow store these calibration constants inside some NVM available to Mycodo. Routines would need to be created to der…
