Finding TDS Sensor Parts
Thought for 3 mins 4 sec
I searched the Flux library for a TDS/EC sensor and probe. Nothing suitable turned up yet.
- TDS sensor: no results. Browse: TDS sensor
- TDS probe: no results. Browse: TDS probe
Conductivity sensor query returned an unrelated current sensor (not applicable for water TDS/EC):

Quick questions to narrow the search:
- 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.
