The value can reflect the cleanliness of water and can be applied to water quality testing in the fields of domestic water and hydroponics.(Total Dissolved Solids): Indicates how many milligrams of dissolved solids are dissolved in 1 liter of water. In general, the higher the value, the more lysate is contained in the water and the more unclean the water. Therefore, the size of the can be used as one of the basis for reflecting the cleanliness of the water.The commonly used testing equipment is a pen. Although it is inexpensive and easy to use, it cannot transmit data to the control system, do long-term online monitoring, and analyze the water quality. Using a special instrument, although the data can be transmitted, the accuracy is high, but the price is very expensive. To this end, we have specially introduced this compatible sensor, which can be used to measure the value of water after connecting to the controller.this product is plug and play and easy to use. The wide voltage supply 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 the ready-made control system. The excitation source used for measurement uses an AC signal, which can effectively prevent probe polarization, extend probe life, and increase the stability of the output signal. The probe is a waterproof probe that can be immersed in water for long periods of time.The product can be applied to water quality testing in the fields of domestic water, hydroponics and the like. With this sensor, you can easily DIY a detector, and easily check the cleanliness of the water to make your water quality better.
