DESCRIPTION The Analog TDS Sensor is used for measuring the TDS value of the water, to reflect the cleanliness of the water. TDS meter can be applied to domestic water, hydroponic and other fields of water quality testing. 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. Therefore, the TDS value can be used as one of the references for reflecting the cleanliness of water. TDS pen is widely used equipment to measure TDS value. With an Arduino controller, you can build a TDS detector easily to measure the TDS value of liquid. This tds sensor supports 3.3 ~ 5.5V wide voltage input, and 0 ~ 2.3V analog voltage output, which makes it compatible with a 5V or 3.3V control system or board. The excitation source is an AC signal, which can effectively prevent the probe from polarization and prolong the life of the probe, meanwhile, increase the stability of the output signal. The TDS probe is waterproof, it can be immersed in water for a long time measurement. Attention: The probe can not be used in water above 55°C. The probe can not be left too close to the edge of the container, otherwise, it will affect the reading. The head and the cable of the probe are waterproof, but the connector and the signal transmitter board are not waterproof. Please be careful.
