Tip

This product can also be compatible with Raspberry Pi Series with the help of 4-Channel 16-Bit ADC For Raspberry Pi (ADS1115)!

Features

  • Analog Signal, easy to implement
  • Support 3.3/5V Input Voltage
  • Good Arduino Compatibility, where 0 ~ 2.3V Output Voltage can be easily implemented in 3.3/5V control system
  • Waterproof TDS Probe
 

Description

The Grove - TDS Sensor detects the Total Dissolved Solids (TDS) levels in the water which can be used to indicate the water quality. The Grove - TDS Sensor can be applied in water quality applications such as TDS meter, well water, aquarium, hydroponics, etc.

 

It supports 3.3/5V input voltage and 0 ~ 2.3V Output Voltage making it easy to be compatible with all Arduino Boards. The sensor also provides a waterproof probe, making the testing process much easier to handle.

 

What is TDS and why should you care

TDS = Total Dissolved Solids, is a measure of the dissolved combined content of all inorganic and organic substances present in water. Typically, the higher the TDS value, the more substances dissolved in water. Hence, higher levels of Total Dissolved Solids (TDS) can indicate that water has more contaminants that can pose health risks.

  • Will it work with raspberry pi specifically with grove raspberry pi HAT?
    Question by: Ajay Gore on 2020-01-27 08:01:17
  • As this sensor is non-isolated it will present an issue with multiple other sensors on the same circuit in the same aqueous solution affecting all measurements, correct?
