Do you want a module with electronics and analog/I2C output, or just a bare probe?
Supply/interface constraints? For your NodeMCU-12E, should it run at 3.3 V and output within the ADC range?
Water type/range? (e.g., 0–2000 ppm freshwater vs higher salinity)
If you have a target model or MPN (e.g., the exact vendor module you want), share it and I’ll look it up directly and propose an in-library match. Also, if we end up with a bare probe + external electronics, I can source the connector and supporting parts once you confirm the direction.
Note: When feeding an MCU ADC from sensor electronics, keep output impedance low or add a small capacitor at the ADC pin to ensure the sample-and-hold acquires accurately. For high-impedance outputs, a buffer op-amp or a 100 nF capacitor near the ADC input is recommended.
Wirelessly connects nets on schematic. Used to organize schematics and separate functional blocks. To wirelessly connect net portals, give them same designator. #portal
