I am looking to add temp sensors in my refrigerator & possibly a sensor reading supply air from my AC. What types of sensors do I need?

Temp sensors for Cerbo GX
Hi @DFraizer,
you'll need the temperature sensor for Quattro, MultiPlus and Venus GX, which is also good for the Cerbo GX. See: https://www.victronenergy.com/accessories/temperature%20sensor%20qua%20pmp%20venus%20gx?_ga=2.10551028.1933131784.1590438491-1969333987.1588075539
I appreciate the answer, but the temp sensor for the multiples does not seem appropriate for a refrigerator. Will a 2 wire sensor work?
The sensor for the MultiPlus is exactly designed for such things. The big cable lug is electrically isolated as is the rest of the sensor.
So can I use the temp sensor that came with my Multiplus 12/3000 and hook it to my Cerbo and simply expose the lug to the outdoors and get a reading from that?
hello
use LM335 TO-92 sensor.

hello
inexact, le capteur d'un M+ est une sonde LM 335Z dont la plage d'utilisation habituelle est de
- 40/+120°C ... donc parfaitement utilisable pour un frigo.
2 fils = no adjust possibilities, 3 fils= adjust possibilities

I made myself these.
See my post in this thread.
These are attached to my Rpi 3B+ but they should work on a real GX device.
Hi
Yes i use those on my raspi systems and they work perfectly. I fit them into a stainless steel tube enclosure, as per photo.
Looks good, Rob. Where did you find the stainless tubing?
