The commonly used TDS testing equipment is a TDS 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 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. The wide voltage supply of 3.3~5.5V and the analog signal output of 0~2.3V make this product compatible with the 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 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 DIY a TDS detector, and easily check the cleanliness of the water to make your water quality better.

Features:

1. Wide voltage operation: 3.3~5.5V
2. 0~2.3V analog signal output, compatible with 5V, 3.3V two control systems
3. The excitation source is an AC signal, effectively preventing probe polarization.
4. Waterproof probe for long-term immersion in water
5. Arduino compatible, easy to connect, plug and play, no soldering required.

   Package Includes:

   1 x Analog TDS Sensor Module
