Analog TDS Water Quality Sensor (OT3480)

This Analog TDS Sensor Module is an Arduino compatible TDS sensor/Sensor kit for measuring the TDS value of water based on conductivity. Suitable for 5.5V or 3.3VThis module is suitable for Arduino controllers, plug and play, and easy to use. Water quality is measured based on TDS value. TDS (Total Dissolved Solids) indicates how many milligrams of soluble solids are dissolved in one liter of water. In general, the higher the TDS value, the more soluble solids are present in water and the less clean the water is. Therefore, the TDS value can be used as a variable to test the purity of water. This TDS value is determined by determining the total amount of various organic or inorganic substances dissolved in water, in the unit of ppm or milligram per liter (mg/l). The electrode measures the conductivity of, for example, suspended solids/solids, heavy metals and conductive ions in water. The module is supplied with four fixed holes of 3.2 mm, and is therefore easy to mount on other devices. The TDS probe is waterproof and can be immersed in water for long-term measurements.
