Description
Features:
| CATEGORY | SPECIFICATIONS |
|---|---|
| Product name | Gravity analog TDS sensor/meter for Arduino |
| Function | Measures total dissolved solids (TDS) in water to indicate water cleanliness |
| Sensor type | Analog TDS (Total Dissolved Solids) water quality sensor |
| Operating principle | Uses AC excitation signal to measure ion concentration in water and prevent probe polarization |
| TDS definition | Total Dissolved Solids indicates the amount of soluble solids (mg/L or ppm) dissolved in water |
| Measurement range | 0 – 1000 ppm |
| Measurement accuracy | ±10% F.S. (at 25 °C) |
| Output type | Analog voltage output |
| Output voltage range | 0 – 2.3 V |
| Supply voltage | 3.3 – 5.5 V |
| Working current | 3 – 6 mA |
| Microcontroller compatibility | Compatible with 3.3 V and 5 V Arduino and other MCU platforms |
| Probe type | Waterproof probe (needle type, 2-pin electrode) |
| Probe length | 83 cm |
| Interface types | PH2.0-3P (module), XH2.54-2P (probe connection) |
| Module size | 42 × 32 mm |
| Special features | Plug-and-play design, AC excitation for stability, waterproof probe for long-term immersion |
| Usage limitations | Do not use in water above 55 °C; avoid placing probe too close to container edges; connector and transmitter are not waterproof |
| Applications | Domestic water testing, hydroponics, water quality monitoring, smart agriculture, liquid purity measurement systems |
