TDS Meter V1.0 Module Water Quality Sensor for Arduino

Input and Output

• Input: The sensor measures the conductivity of the water, which correlates to the TDS level.
• Output: Provides an analog voltage signal that corresponds to the TDS level.

Physical Characteristics

• Dimensions: Compact, usually around 5 cm x 3 cm.
• Material: Plastic housing with a sensor probe.
• Weight: Lightweight and easy to handle.

Technical Specifications

• TDS Range: Measures TDS from 0 to 1000 PPM.
• Output Range: Analog signal from 0 to 5V.
• Accuracy: Typically ±2% of reading.

Additional Features

• Calibration: Simple calibration with standard solutions for accurate readings.
• Easy Integration: Designed to work seamlessly with Arduino projects.

How to Use

1. Connect the Sensor: Attach the VCC pin to 5V, GND to ground, and AO to an analog input pin on the Arduino.
2. Power On: Provide power to the module.
3. Submerge the Probe: Place the sensor probe in the water to be tested. Ensure it is fully immersed for accurate measurements.
4. Read the Data: Use the analog signal from the sensor to determine the TDS level. The analog value will vary based on the TDS concentration.
5. Calibrate: If necessary, calibrate the sensor using standard TDS solutions to ensure accurate readings.

This TDS Meter V1.0 Module provides an effective and straightforward way to measure water quality and integrate it into Arduino-based projects, helping to monitor and control various water-related processes.
