The commonly used TDS detection device is a TDS pen. Although it is inexpensive and easy to use, it cannot transmit data to the control system for long-term online monitoring and water quality analysis. Using specialized instruments, although data can be transmitted and accuracy is high, the price is expensive.
Therefore, we have specifically developed this Arduino compatible TDS sensor, which can be connected to an Arduino controller to measure the TDS value of water.
FEATURES
- Specifically designed for Arduino with gravity interface, making wiring simple, plug-and-play, and no soldering required. Easy and convenient to use.
- The TDS probe is waterproof and can be submerged in water for long-term measurements.
- This TDS sensor has a wide voltage supply of 3.3~5.5V and an analog signal output of 0~2.3V, making this product compatible with 5V and 3.3V control systems, and easily integrated into existing control systems.
- The excitation source for measurement uses an AC signal, effectively preventing probe polarization, prolonging probe lifespan, and increasing output signal stability.
Board Overview
- 1 – Power GND(0V)
- 2 + Power VCC(3.3 ~ 5.5V)
- 3 A Analog Signal Output(0 ~ 2.3V)
- 4 TDS TDS Probe Connector
- 5 LED Power Indicator
Attention:
- The probe cannot be used in water above 55 degrees Celsius.
- The probe cannot be left too close to the edge of the container; otherwise, it will affect the reading.
- The head and the cable of the probe are waterproof, but the connector and the signal transmitter board are not waterproof. Please be careful.

FAQ
Q1. Does this sensor have a temperature sensor? How to make the temperature compensation?
A1. This TDS probe has no temperature sensor, but the temperature compensation algorithm is reserved in the sample code. The temperature variable in the sample code will default to 25 °C without a temperature sensor. You can add a waterproof temperature sensor to read the temperature,then update the temperature variable, to make automatic temperature compensation.
