This is an Arduino-compatible TDS sensor / meter kit for measuring water TDS value, to reflect water cleanliness. It can be applied to water for domestic, hydroponic and other water quality testing fields. You can also check the Sensor Selection Guide Fluid to get a better familiarity with our standard sensor liquid.
TDS (Total Dissolved Solids) indicates that the number of milligrams of soluble solids dissolved in one liter of water. In general, the higher the TDS value, the more soluble in solids dissolved in water, and the less clean the water is. Therefore, the TDS value can be used as one of the references to reflect water cleaning .
TDS pen is a widely used equipment to measure TDS value. The price is cheap, and it's easy to use, but it's not able to transmit data for the online monitoring control system to do some quality analysis water. The professional tool has high precision and can send data to the control system, but the price is expensive for ordinary people. To this end, we have launched an analogue TDS tester kit that is compatible with Arduino, plug and play, easy to use. Combined with the Arduino controller, it is possible to build a detector TDS easily to measure the TDS value of liquid.
This product supports 3.3 ~ 5.5V wide voltage input, and 0 ~ 2.3V analog output voltage, which makes it compatible with 5V or 3.3V control system or on-board. The excitation source is AC signal, which can effectively prevent the polarization probe and prolong the life of the probe, meanwhile, increase the stability of the output signal. The probe TDS is waterproof, it can be immersed in water for a long measuring time.
This product can be used in water of application quality, for example as water for domestic use, hydroponics. With this product, you can easily DIY a detector TDS to reflect the cleanliness of water to protect your health.
1. the probe cannot be used in water higher than 55 degrees centigrade.
2. the probe cannot be left too close to the edge of the container, otherwise the reading will be impaired.
3. the probe head and cable are waterproof, but the connector and the on-board signal transmitter are not waterproof. Please be careful.
