TDS meter can be applied to domestic water, hydroponic and other fields of water quality testing.\u003c\/p\u003e\n\u003cp\u003eTDS (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.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E38015-content1.webp?v=1791333817\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e(Cited from Google)\u003c\/p\u003e\n\u003cp\u003eFor this application, we have launched an analog TDS sensor kit that is compatible with Arduino, plug, and play, easy to use. Matching with Arduino controller, you can build a TDS detector easily to measure the TDS value of liquid.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E38015-content2.webp?v=1791333868\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cb\u003e\u003cspan style=\"color: #ff9c00;\"\u003e Attention:\u003c\/span\u003e\u003c\/b\u003e\u003cbr\u003e1.The probe can not be used in water above 55 degrees centigrade.\u003cbr\u003e2.The probe can not be left too close to the edge of the container, otherwise, it will affect the reading.\u003cbr\u003e3.The head and the cable of the probe are waterproof, but the connector and the signal transmitter board are not waterproof.

TDS alone cannot determine whether water is safe to drink and does not identify bacteria or specific contaminants. The probe may be immersed as documented; keep the signal board and connector dry. Temperature compensation requires a separate temperature measurement. Raspberry Pi projects also need an appropriate ADC.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eWide Voltage Input: 3.3~5.5V\u003c\/li\u003e\n\u003cli\u003eGood Compatibility Output: 0~2.3V analog signal output, compatible with 5V or 3.3V controller\u003c\/li\u003e\n\u003cli\u003eAC Excitation Source: effectively prevent the probe from polarization\u003c\/li\u003e\n\u003cli\u003eWaterproof Probe\u003c\/li\u003e\n\u003cli\u003eEasy to Use: Arduino compatible, simple connection, plug, and play without soldering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cp\u003eSignal Transmitter Board\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eInput Voltage: 3.3 ~ 5.5V\u003c\/li\u003e\n\u003cli\u003eOutput Voltage: 0 ~ 2.3V\u003c\/li\u003e\n\u003cli\u003eWorking Current: 3 ~ 6mA\u003c\/li\u003e\n\u003cli\u003eTDS Measurement Range: 0 ~ 1000ppm\u003c\/li\u003e\n\u003cli\u003eTDS Measurement Accuracy: ± 10% F.S.
