Description:
DFRobot Gravity: Analog TDS Sensor/Meter for Arduino is an Arduino-compatible TDS Meter Kit 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 with this product, you can easily DIY a TDS detector to reflect the cleanliness of water to protect your health.
TDS (Total Dissolved Solids) indicates how many milligrams of soluble solids are 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.
The probe can not be used in water above 55 degrees centigrade.
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.
