CQRobot TDS (Total Dissolved Solids) Meter Sensor Compatible with Raspberry Pi/Arduino Board. for Liquid Quality Analysis Teaching, Scientific

Wide Voltage Input: 3.3V to 5.5V. Good Compatibility Output: 0 to 2.3V analog signal output, compatible with 5V or 3.3V controller. AC Excitation Source: effectively prevent probe from polarization, Waterproof Probe. Easy to Use: Arduino compatible, simple connection, plug and play without soldering. Used with ADS1115 16-Bit ADC Module (ASIN: B08KFZ3PVT, Model: CQRADS1115), Compatible with Raspberry Pi Motherboard. Note: When using the TDS instrument sensor, the sensor probe is immersed in liquid, and the purchaser needs to Separate the sensor Probe Protective Cover to avoid incorrect data reading and malfunction.

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.
