Water Quality Analog TDS Sensor (DFRobot Gravity)

Out Of Stock



The Gravity: Analog TDS Sensor/Meter for Arduino is a kit that allows you to measure the total dissolved solids (TDS) in water using an Arduino board. TDS is a measure of the dissolved minerals, salts, and other substances in water, and can be used to reflect the cleanliness and quality of the water. This TDS meter kit can be used for a variety of applications, including testing the quality of domestic water, hydroponics, and other fields. It is compatible with Arduino boards and can be easily integrated into a variety of projects. Yes, the Gravity: Analog TDS Sensor/Meter for Arduino is designed to be compatible with a wide range of voltage inputs, from 3.3V to 5.5V, making it compatible with both 5V and 3.3V control systems or boards. It also has an analog voltage output range of 0V to 2.3V, which allows it to be easily integrated into a variety of projects. One of the key features of this TDS sensor is its use of an AC signal as the excitation source. This can help prevent polarization of the probe, which can extend its lifespan and improve the stability of the output signal. Additionally, the TDS probe is waterproof, allowing it to be immersed in water for long periods of time for measurement purposes.
