Feature: 1. The for compatible TDS sensor is used to measure the TDS value of water. And the TDS value reflects the cleanliness of the water.2. Also, it can be used for water quality testing in the field of domestic water and hydroponics. 3. TDS Indicates how many milligrams of dissolved solids are dissolved in 1 liter of water. Generally, the higher TDS value means that the more lysate is contained in the water and the less cleanness of water. 4. Therefore, the size of the TDS can be used as one of the basis for reflecting the cleanliness of the water. And the product is plug and play and easy to use. Also, the wide supply voltage of 3.3~5.5V and the analog signal output of 0~2.3V make this product compatible with 5V, 3.3V control system, which can be easily used in off-the-shelf control systems. The excitation source is used for measurement by using an AC signal to effectively prevent probe polarization, extending probe life and increasing the stability of the output signal. Meanwhile the TDS probe is a waterproof probe that can be immersed in water for a long time. Furthermore, this product can be used for water quality testing in areas such as domestic water and hydroponics. With this sensor, you can easily make your own TDS detector and easily check the cleanliness of the water to improve water quality. 5. A commonly used TDS tester is a TDS pen. Although inexpensive and easy to use, it does not transfer data to the control system, enabling long-term online monitoring and analysis of water quality. Using a dedicated instrument, although it can transmit data, it is very accurate, but it is very expensive. To this end, we specifically introduced this for -compatible TDS sensor, which can be used to measure the TDS value of water after it is connected to the controller.
