TDS Meter V1.0 Module

🔹 TDS Meter V1.0 Water Quality Sensor Module – Analog TDS Sensor for Arduino

The TDS Meter V1.0 is an analog sensor module designed to measure the Total Dissolved Solids (TDS) in water, providing an indication of water purity. It’s commonly used in water quality monitoring for domestic water, hydroponics, and aquariums .

✅ Specifications:

Input Voltage: DC 3.3V – 5.5V

Output Voltage: 0 – 2.3V (analog signal)

Working Current: 3 – 6mA

Measurement Range: 0 – 1000ppm

Measurement Accuracy: ±10% Full Scale (@25°C)

Module Interface: XH2.54-3P

Electrode Interface: XH2.54-2P

Probe Length: 60cm (waterproof)

Module Dimensions: 42mm × 32mm

📦 Features:
✔️ Analog voltage output proportional to TDS value
✔️ Compatible with 3.3V and 5V microcontrollers
✔️ Waterproof probe for submersion in water
✔️ Low power consumption (3–6mA)
✔️ AC excitation source prevents probe polarization
✔️ Plug-and-play – no soldering required
✔️ Comes with 4 mounting holes for easy installation

📦 Applications:
✔️ Domestic drinking water quality testing
✔️ Hydroponics and agriculture water monitoring
✔️ Aquariums and fish tanks
✔️ Industrial water treatment systems
✔️ Environmental water testing
✔️ IoT and Arduino-based water quality projects

⚠️ Important Notes:

Probe cannot be used in water above 55°C

Probe and cable are waterproof, but the sensor module board is not

Keep probe away from container edges to avoid reading interference

Calibration recommended for accurate measurements
