TDS is an abbreviation for Total Dissolved Solids in a liquid, including organic and inorganic substances in a molecular, ionic, or micro-granular suspended form. All the components can be easily purchased from Amazon. In order to know more about water quality, you can add Ph Sensor, Turbidity Sensor & DO Sensor to this circuit as well.įollowing are the components required for making this project. The code, circuit diagram, and all other procedure is given below. The measured temperature is used with TDS Sensor to compensate for the reading with high calibration and high accuracy. So will also add DS18B20 Waterproof Temperature Sensor to measure Water Temperature. Since TDS Value depends upon the temperature.

So, in this project, we will interface Gravity Analog TDS Sensor with Arduino Microcontroller and read the value in 16×2 LCD Display. This can be applied to domestic water, hydroponic and other fields of water quality testing and monitoring. Therefore, the TDS value can be used as one reference point for reflecting the cleanliness of the water. In general, the higher the TDS value, the more soluble solids are dissolved in water, and the less clean the water is. TDS (Total Dissolved Solids) indicates how many milligrams of soluble solids are dissolved in one liter of water. Source Code/Program with Temperature Compensation.
