TDS Water Conductivity Sensor for Arduino - (AD12150)

Description:

TDS (Total Dissolved Solids) conductivity sensor for water quality monitoring. Compatible with Arduino and similar platforms, it allows for the detection and analysis of total dissolved solids concentration in liquids. Ideal for DIY real-time monitoring projects, aquariums, filtration systems, and environmental control applications. Includes an interface for easy integration and simple calibration. Perfect for electronics enthusiasts and professionals requiring accurate water quality data.

TDS, also known as Total Dissolved Solids, indicates the number of milligrams of dissolved solids in 1 liter of water. In general, the higher the TDS value, the greater the amount of dissolved substances in the water and the less pure it is. Therefore, the TDS value can be used as one of the indicators to evaluate water purity.

This product is specially designed for Arduino, is plug and play, and easy to use. Its wide supply voltage range (3.3~5.5V) and analog signal output (0~2.3V) make it compatible with both 5V and 3.3V control systems, and it can be easily connected to existing control systems.

The excitation source for measurement uses AC signals, which effectively prevents probe polarization, extends its service life, and increases the stability of the output signal. The TDS probe is waterproof and can be submerged in water for long-term measurements. This product can be used to analyze water quality at home, in hydroponics, and other fields. With this sensor, you can easily build a TDS detector, check water purity, and verify its quality.
