This equipment can be used to measure the general quality of the water in the home.
Typically, the TDS of tap water is within 100 (about 90 in Shenzhen) and purified water is within 10.
Arduino compatible TDS sensor is used to measure the TDS value of water. The TDS value can reflect the cleanliness of the water and can be applied to water quality tests in the fields of domestic water and hydroponics.
TDS (Total Dissolved Solids): indicates how many milligrams of dissolved solids are dissolved in 1 liter of water. In general, the higher the TDS value, the higher the level of lysation in the water and the cleaner the water. Therefore, the size of the TDS can be used as one of the bases to reflect the cleanliness of the water.
Commonly used TDS test equipment is a pencil for measuring TDS. Although it is cheap and easy to use, it cannot transmit data to the control system, do long-term online monitoring, and analyze water quality. Using a special instrument, although the data can be transmitted, the precision is high, but the price is very expensive. To this end, we have specially introduced this Arduino compatible TDS sensor, which can be used to measure the TDS value of water after connecting to the Arduino controller.
Designed for arduino, this product is plug and play and easy to use. 3.3 ~ 5.5V wide voltage source and 0 ~ 2.3V analog signal output make this product compatible with 5V, 3.3V control system, which can be used easily in the prepared control system. The excitation source used for measurement uses an AC signal, which can effectively prevent probe polarization, extend the life of the probe, and increase the stability of the output signal. The TDS 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 mount a TDS detector and easily check the cleanliness of the water to improve the water quality.
Notice:
TDS probes cannot be used in water above 55 ° C.
The TDS probe should not be placed too close to the edge of the container as it will affect the screen.
The head and cable of the TDS probe are waterproof and can be submerged in water, but the connection interface and signal adapter board are not waterproof. Pay attention to the use.
