DFRobot Gravity analog sensor of TDS and purity of water for Arduino

Analog TDS sensor compatible with Arduino, it is used for measuring the hardness and the purity of water. It can be used to test the quality of water in households, hydroponic farms and others. TDS (Total Dissolved Solids) indicates how many substances were dissolved in one liter of water. The higher the TDS value, the more substances the water contains, therefore it is more polluted. The sensor is measuring the TDS in the range of 0 ppm to 1000 ppm. It is powered with the voltage from 3.3 V to 5.5 V.

Specification:

• Input voltage: from 3.3 V to 5.5 V
• Output voltage: 0 V to 2.3 V
• Working current: 3 to 6 mA
• Measuring range TDS: from 0 ppm to 1000 ppm
• Measurement accuracy TDS: ±10% F. S. (25 ℃)
