About the item
TDS (Total Dissolved Solids) indicates that how many milligrams of soluble solids dissolved in one liter of water. In general, the higher the TDS value, the more soluble solids dissolved in water, and the less clean the water is. CQRobot has launched an arduino-compatible TDS sensor, which can be used to measure the TDS value of water after connecting to the arduino controller, plug and play.
3.3V to 5.5V wide voltage power supply, 0 to 2.3V analog signal output, making this product compatible with 5V and 3.3V control systems. With CQRobot ADS1115 16-Bit ADC Module (ASIN: B08KFZ3PVT and Model: CQRADS1115), it can accurately collect and convert analog signals to meet the compatibility requirements of the Raspberry Pi board.
