Special Features

  • Product Description: Total Dissolved Solids indicates how many milligrams of dissolved solids are dissolved in 1 liter of water. Generally speaking, the higher the TDS value, the more dissolved the water contains and the less clean the water is. This TDS sensor module. The module is plug and play, and easy to use. It can be used for water quality testing in the fields of domestic water and hydroponics. The sensor can easily DIY a set of TDS detectors to easily detect the cleanliness of the water
  • ▷Technical indicators: Supply voltage: 3.3~5.0V. Output signal range: 0~2.3V. Working current: 3~6mA. TDS measurement range: 0~1000ppm. TDS measurement accuracy: ±5% F.S. (25℃). Module size: 42mm×31.2mm. TDS probe interface: 2Pin XH-2.54. Temperature sensor interface: 3Pin XH-2.54.
  • ▷Features: (1) Wide voltage operation: 3.3~5.5V (2) 0~2.3V analog signal output, compatible with 5V and 3.3V control systems (1) The excitation source is an AC signal, which effectively prevents the probe from being polarized (2) Waterproof probe, which can be immersed in water for a long time to measure
  • ▷Pin function description: VCC: Positive supply voltage, 5V or 3.3V GND: negative power supply voltage T1: temperature sensor DS18B20 signal output port, temperature compensation can be performed by software AO: analog signal output, output voltage range 0-2.3V +: temperature sensor power supply positive T: temperature sensor signal line -: Negative pole of temperature sensor power supply 1: TDS probe lead 1 2: TDS probe lead 2
  • ▷Precautions: 1. The TDS probe cannot be used in water above 55°C. 2. The position of the TDS probe should not be too close to the edge of the container, otherwise the reading will be affected. 3. The TDS probe head and wire are waterproof and can be immersed in water, but the connection interface and the signal adapter board are not waterproof, please pay attention to use.
