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 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.
Highlighted 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
