APEX FMM Fluid monitoring monitor DIY sensors

[dactylo]

Is it possible to use this water level sensor with the FMM? It uses the same voltage and current as the apex optical sensors and the nice thing about it is this would never touch the water. It works by using the capacitance changes in the liquid container. These sensors can be found online for around $4.

What happened here?? Did this work?

I’m curious too! Did you get it going?

FYI:

Optical Sensor Alternative for FMM - Contactless Liquid Level Sensor

I was looking into adding optical sensors to monitor my 2-part dosing container levels, but adding 2 OS-1Ms at $35 a pop wasn't appealing, especially since I just had to replace a OS-1 that died on me after just over 1 year of use. Ebay/amazon have identical looking optical sensors for much...
