1pcs TDS Sensor Water Conductivity & Quality Board Module

Product Introduction

This is an Arduino-compatible TDS sensor used to measure the TDS value of water. The TDS value can reflect the cleanliness of water and is suitable for water quality detection in fields such as domestic water and hydroponics.

TDS (Total Dissolved Solids) refers to the milligrams of dissolved soluble solids in 1 liter of water. Generally, the higher the TDS value, the more dissolved substances in the water and the dirtier the water. Its value can be used as one of the bases to reflect the cleanliness of water.

Features

Wide voltage operation: 3.3 - 5.5V

0 - 2.3V analog signal output, compatible with both 5V and 3.3V control systems

The excitation source is an AC signal, effectively preventing probe polarization

Waterproof probe, can be immersed in water for long-term measurement

Compatible with Arduino, using Gravity interface, simple wiring, plug-and-play, no welding required

Precautions

The TDS probe cannot be used in water above 55°C.

The TDS probe should not be placed too close to the edge of the container, otherwise it will affect the reading.

The head and wire of the TDS probe are waterproof and can be immersed in water, but the connection interface and the signal adapter board are not waterproof. Please pay attention when using.
