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 meters, 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 Grove?
We have developed more than 400 Grove modules, covering a wide range of applications that can fulfil various needs. Click to explore the Grove Sensor family and get started to Grove your Idea. For all Grove users (especially beginners), we provide you with guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your use of the product.
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.
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!
