Analog TDS Water Conductivity Sensor Module Kit – Arduino-Compatible TDS Meter for Water Quality Testing

Product Description:
The Analog TDS Sensor Water Conductivity Sensor Module Board Kit is a high-quality, Arduino-compatible TDS meter designed to measure the Total Dissolved Solids (TDS) value in water. Ideal for hydroponics, aquariums, water purification systems, and environmental monitoring, this sensor accurately reflects the cleanliness and mineral content of water.

Operating on a wide voltage range (3.3V–5.5V) and providing a 0–2.3V analog output, this TDS sensor module is fully compatible with both 3.3V and 5V control systems, including Arduino, ESP32, and Raspberry Pi. The included waterproof probe allows for long-term immersion and continuous measurement in liquid environments, making it reliable for real-world applications.

Using an AC excitation signal, the module effectively prevents probe polarization and ensures stable, accurate readings. Its compact design and plug-and-play connectivity make it easy to integrate into existing systems for instant water quality analysis.
