**Advantages and Performance:**

This product is distinguished by its broad compatibility (5V and 3.3V systems) and its easy "plug and play" operation.

Its excitation source uses an alternating current (AC) signal, which effectively prevents electrode polarization, thus extending the probe's lifespan and ensuring high output signal stability. Its compact design makes it easy to transport and store. **Applications:** Ideal for measuring water quality in various contexts, such as domestic water or hydroponics. It measures Total Dissolved Solids (TDS), a key indicator of water cleanliness. Tap water typically has a value below 100 ppm, while purified water is usually below 10 ppm. Unlike simple manual testers, this sensor allows for online monitoring and data transmission to your control system, all at a very affordable price. With this sensor, you can easily create your own monitoring system to check and improve your water quality. **Package Contents:** 1 x Water Conductivity Sensor (complete with adapter board and waterproof probe).
