Water TDS / Conductivity Sensor for Water Quality Monitoring

This is a microcontroller-compatible TDS Meter Kit for measuring TDS value of the water, to reflect the cleanliness of the water. It can be applied to domestic water, hydroponic and other fields of water quality testing.
TDS (Total Dissolved Solids) indicates that how many milligrams of soluble solids dissolved in one liter of water. In general, the higher the TDS value, the more soluble solids dissolved in water, and the less clean the water is. Therefore, the TDS value can be used as one of the references for reflecting the cleanliness of water.
TDS pen is a widely used equipment to measure TDS value. The price is affordable, and it is easy to use, but it is not able to transmit data to the control system for online monitoring to do some water quality analysis. The professional instrument has high accuracy and can send data to the control system, but the price is high for the ordinary people. To this end, we have launched an analog TDS senser kit which is compatible with Arduino, plug and play, easy to use. Matching with Arduino controller, you can build a TDS detector easily to measure the TDS value of liquid.
This product supports 3.3 ~ 5.5V wide voltage input, and 0 ~ 2.3V analog voltage output, which makes it compatible with 5V or 3.3V control system or board. The excitation source is AC signal, which can effectively prevent the probe from polarization and prolong the life of the probe, meanwhile, increase the stability of the output signal. The TDS probe is waterproof, it can be immersed in water for long time measurement.

 

Features

  • Wide voltage operation: 3.3~5.5V
  • 0~2.3V analog signal output, compatible with 5V, 3.3V two control systems
  • The excitation source is an AC signal, effectively preventing probe polarization.
  • Waterproof probe for long-term immersion in water
  • Compatible, easy to connect, plug and play, no soldering required.

 

Specifications:

  • Input voltage: 3.3~5.5V
  • Output signal: 0~2.3V
  • Working current: 3~6mA
  • TDS measurement range: 0~1000ppm
  • TDS measurement accuracy: ±10% F.S. (25°C)
  • Size: 42x32mm
  • Module interface: XH2.54-3P
  • Electrode interface: XH2.54-2P
  • Number of probes: 2
  • Overall length: 80cm

Notes:

  • TDS probes cannot be used in water above 55 °C.
  • The TDS probe should not be placed too close to the edge of the container, as it will affect the display.
  • The head and lead of the TDS probe 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.
