Description
An Arduino-compatible TDS(Total Dissolved Solids) sensor/meter for measuring TDS levels in water to indicate the water quality. It can be implemented in fields such as homemade water filters, hydroponics, aquarium and others related to testing water quality.
Features
- Analog signal, high accuracy measuring: The TDS measurement range is 0-1000ppm.
- Waterproof TDS probe: Use a waterproof TDS probe not easier corroded by water
- Good compatibility: Where 0 ~ 2.3V output voltage can be easily implemented in 3.3/5V control system
- Grove unified socket: The product ensures “Plug and Play” and could be versatile for various applications of Grove
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!

Among the water quality detection of aspect that has the following range to choose from:
Grove – ORP Sensor Kit (HR-O) measures the ORP value, detecting the quality of the liquid. It works with a 5-meter IP68 ORP probe, offering a -2000mV to 2000mV sensing range, operating under 0-80℃.
The electrical conductivity sensor (EC sensor) measures the electrical conductivity in a solution which usually used for aquaculture and water quality testing.
The PH sensor measures the hydrogen-ion activity in water-based solutions, we usually use it to measure the PH of a liquid.
This 2m long One Wire Temperature Sensor has a waterproof probe and long wire shape, suitable for immersive temperature detection.
