Analog TDS Sensor Module Water Quality Detection Kit for STM32/51

The Analog TDS Sensor Module is a professional-grade water quality detection kit designed for microcontrollers like STM32, 8051 (51 series), and Arduino. It measures Total Dissolved Solids (TDS)—the concentration of dissolved minerals, salts, and metals—to provide a reliable indicator of water purity. The module converts the water's conductivity into a stable 0–2.3V analog voltage, which can be easily processed by any standard ADC. Featuring an AC excitation source to prevent probe polarization and a fully waterproof sensing probe, this module is built for long-term online monitoring in home water purifiers, hydroponic systems, and environmental research projects. Its wide 3.3V–5.5V operating range ensures seamless integration with both modern 3.3V ARM cores and traditional 5V logic systems.

Key Features:

• Analog Voltage Output: Simple 0–2.3V signal proportional to 0–1000ppm TDS levels.
• Anti-Polarization Design: AC excitation source extends probe life and improves output stability.
• Waterproof Probe: Durable, long-term immersion probe included for continuous monitoring.
• Universal Compatibility: Works with STM32, 8051, Arduino, ESP32, and Raspberry Pi.
• Plug-and-Play Setup: 3-pin interface (VCC, GND, Analog Out) for quick circuit integration.
• High Precision: Accurate within ±10% for reliable water cleanliness assessment.
