Features:

1. TDS Measurement: This development board is equipped with a compatible TDS sensor designed for measuring the Total Dissolved Solids (TDS) value of water. It helps in assessing water cleanliness and is suitable for water quality detect in domestic water and hydroponics.
2. Wide Voltage Compatibility: With a wide voltage operation range of 3.3~5.5V, this sensor is compatible with both 5V and 3.3V control systems, making it easy to integrate into existing control setups.
3. AC Signal Excitation: The sensor uses AC signals for measurement, effectively preventing probe polarization. This feature extends the probe's lifespan and enhances the stability of the output signal.
4. Waterproof Probe: The TDS probe is waterproof, allowing it to be immersed in water for long-term measurements. This makes it suitable for various applications, including domestic water and hydroponics.
5. for Arduino: Designed specifically for Arduino, this sensor offers simple plug-and-play connectivity without requiring any soldering. It simplifies the process of creating a TDS detector for monitoring water cleanliness.
