Concerned about your water quality? Why not make yourself a TDS meter to monitor water quality to tell you whether the water meets standards of drinking! 

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.

Applications

• TDS meter/TDS tester
• Swimming pool
• Aquarium
• Well water
• Hydroponics
