I bought this PH sensor and I have a pi 3b+ and pi zero
What is the best way to get this into cayenne?
I’ve read some stuff like use one of these Electrochemical Sensing Circuit - Compatible Microprocessor UART or I2C Protocol
But I also read it would be easier to just hook the analog output pin from the PH meter to one of the adafruit ADS1115 16-Bit ADC - 4 Channel with Programmable Gain
What would be the easier way? I like the idea of using the adafruit analog to digital.
If i add it as new device is there a way to calibrate it? to show the correct ph values? I have ph 4 and 7 here but how does configuring cayenne work?
secondary if I use the adafruit digital to analog converter can I add some soil sensors to it too?I’ve read they can meter on the analog pin but the normal digital way to hook them to a pi only does 0/1 on/off.
