Hey! I'm about to buy a Hydros X4 but I wanted to see if I could skip the overpriced optical water level sensor and temperature sensor since I have some lying around that I was hoping could be easily connected to the X4.
I'm pretty sure the temp sensor used in the hydros is the DS18B20 and the optical water level sensor is the same as any other 4 cable Chinese optical water level sensor.
I would be very grateful if someone could post a photo of the cable arrangement inside the DX12 connector of these sensors.
My guess so far for the DS18B20:
+/5v to pin 2
-/GND to pin 1
line to pin 3
For the optical water sensor I guess I would need the small DF-Robot PCB (photo attached) that converts the 4 wires to 3 wires and then:
+/5v to pin 2
-/GND to pin 1
line to pin 4
PS: I've attached a "cheat sheet" for all the hydros ports in case this is helpful for someone, I'm not sure who uploaded it but the credits are for him/her.
Thanks )
