Description
The Gravity: Analog TDS Sensor/Meter for Arduino is a versatile kit designed to measure total dissolved solids (TDS) in water using an Arduino board. TDS indicates the concentration of dissolved minerals, salts, and substances, reflecting water cleanliness and quality. Ideal for various applications such as domestic water testing and hydroponics, this sensor kit offers compatibility with Arduino boards, ensuring seamless integration into diverse projects. With a wide voltage input range of 3.3V to 5.5V, it suits both 5V and 3.3V control systems. Its analog voltage output range of 0V to 2.3V facilitates easy project integration. Notably, it employs an AC signal as the excitation source to prevent probe polarization, enhancing lifespan and signal stability. Additionally, the waterproof probe allows prolonged immersion for accurate measurements.
