You can use the following optical sensor for the main ATO sensor port and the 5 analog ports however you need to add one resistor to the sensor before powering it up, if this resistor is not added the sensor will be damaged.

Your sensor will likely have that white plug on the sensor, cut it off, strip back the wires and before connecting to controller add a 390 ohm resistor to the red wire, direction of the resistor doesn't matter. The other side of the resistor you can push into the green connector for the controller, the other wires connect as described above. The white and blue wire must go to the +5v pin and the yellow wire is the signal which goes to the main ATO sensor port or any of the analog port pins.
Once connected be sure to go settings, hardware, analog sensors and set the port for the optical sensor to "analog sensor".
