About this product
Analog TDS sensor module V1.0 with a waterproof probe for measuring total dissolved solids (TDS) and electrical conductivity (EC) in water. It runs on a 5 V supply and gives an analog voltage output that an Arduino, ESP32 or other microcontroller can read on an ADC pin. Commonly used for RO/DI water checks, aquariums and hydroponic nutrient solutions.

Does the TDS module need calibration?
Yes. TDS readings depend on the probe and the water being measured, so calibrate the module against a reference TDS solution or a reference meter before relying on its values.
How do I connect it to an Arduino or ESP32?
Connect VCC to 5 V, GND to GND and the signal output to an analog input such as A0. On 3.3 V boards like the ESP32, check the output voltage range and use a voltage divider so the ADC input stays within its limit.
