Description
TDS Sensor Meter V1.0 Board Module – Accurate Water Quality Measurement for Arduino & ESP Projects
The TDS Sensor Meter V1.0 Board Module is an essential tool for measuring Total Dissolved Solids (TDS) in water, making it a perfect solution for water quality monitoring in both hobby and professional applications. Whether you’re building a smart IoT water purifier, testing the purity of drinking water, or monitoring hydroponics and aquaponics systems, this sensor delivers precise and reliable readings that help you understand the true quality of your water.
What is TDS and Why It Matters
TDS (Total Dissolved Solids) represents the total amount of dissolved substances in water, such as minerals, salts, and metals. A high TDS level usually indicates impure water, while a lower TDS value suggests cleaner, purer water. Monitoring TDS is crucial for ensuring safe drinking water, maintaining optimal plant growth in hydroponics, and improving the performance of filtration systems.
The TDS Sensor Meter V1.0 converts the electrical conductivity (EC) of water into a readable TDS value, allowing you to easily evaluate the purity of your water with your Arduino, ESP32, or Raspberry Pi.
Key Features
🔹 High Accuracy and Stability:
Built with a high-quality analog TDS probe and signal conditioning circuit to ensure accurate and stable measurements across different water samples.
🔹 Wide Measurement Range:
Capable of detecting TDS values from 0 to 1000 ppm, making it suitable for a wide range of applications—from tap water and well water to aquariums and laboratory testing.
🔹 Analog Output Compatible:
The sensor outputs an analog voltage that can be directly read by Arduino analog pins (A0–A5). It’s easy to calibrate and integrate into any microcontroller-based system.
🔹 Easy Integration with Arduino & ESP Boards:
Fully compatible with Arduino UNO, Mega, ESP8266, ESP32, and other development boards. The module comes with a 3-pin connector for quick connection and setup.
🔹 Corrosion-Resistant Probe:
The included stainless-steel TDS probe ensures long-lasting durability, even with prolonged exposure to water, ensuring consistent readings over time.
🔹 Temperature Compensation Support:
By adding a temperature sensor (like DS18B20), you can achieve temperature-compensated readings, improving accuracy in varying environmental conditions.

How It Works
The TDS Sensor Meter V1.0 works by measuring the electrical conductivity (EC) of water and converting it into a readable TDS value. When connected to an Arduino or microcontroller, the module’s analog output voltage changes according to the water’s conductivity level. Using a simple code, you can easily convert this analog reading into parts per million (ppm) and display it on an LCD, OLED screen, or web dashboard.
Example Connection
-
VCC → 5V (or 3.3V)
-
GND → Ground
-
AOUT → Analog input (e.g., A0 on Arduino)
Optional: Connect a DS18B20 sensor for temperature compensation to enhance reading accuracy.
