Product description

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.
The CQRSENTDS01-TDS sensor can be used to measure the TDS value of water after connecting to the arduino controller. It can be used with CQRobot ADS1115 16-Bit ADC Module (ASIN: B08KFZ3PVT, model: CQRADS1115) to accurately collect and convert analog signals to meet the compatibility requirements of Raspberry Pi motherboards.
Attention: This kit does not include CQRobot ADS1115 16-bit AD conversion module. For technical support, please refer to CQRobot Wiki to get the test code, SKU: CQRSENTDS01.
