TDS Sensor V1.0 Water Quality Measurement Module for Arduino

About this item

This is a TDS sensor/meter kit compatible with Arduino, used to measure the TDS value of water to reflect its cleanliness. It can be used to test domestic water, hydroponics, and other water quality fields.

TDS (Total Dissolved Solids) indicates how many milligrams of dissolved solids are present in one liter of water. In general, the higher the TDS value, the more dissolved solids are in the water and the less clean the water is. Therefore, the TDS value can be used as a reference to reflect the cleanliness of water.

• Input voltage: DC 3.3 ~ 5.5 V

• Output voltage: 0 ~ 2.3 V

• Operating current: 3 ~ 6 mA

• TDS measurement range: 0 ~ 1000 ppm

• TDS measurement accuracy: ±10% F.S. (25 ℃)
