Unfortunately I'm not really sure. If you have a volt meter handy connect the circuit to the controller using a 5v and GND pin to Power + and Power GND. Then with your volt meter check if you have voltage coming out Signal GND and PH output and also see if there's voltage coming out of Signal GND and Level Signal output pins. If it is an analog circuit the voltage should be somewhere between 0-5v so around 2.5v if the PH is 7.0.
If there is voltage in that range and it swings when the PH changes it'll likely work. Do you have Rev A board on version 2 controller? The code is setup using Analog pin 0 which is Sensor 1 port, if you let me know which board you have I can point out the pin location.
