SEN0244 , Gravity: Analog TDS Sensor/ Meter for Arduino

The Gravity: Analog TDS Sensor/Meter for Arduino is a versatile, Arduino-compatible kit designed for measuring the Total Dissolved Solids (TDS) value of water, reflecting its cleanliness. Ideal for domestic water, hydroponics, and other water quality testing applications, this sensor enables easy and efficient water monitoring. TDS represents the amount of soluble solids dissolved in water, making it an important parameter for assessing water quality. Higher TDS values typically indicate less clean water.

Designed to bridge the gap between affordability and functionality, this sensor supports real-time monitoring by transmitting data to control systems. Its plug-and-play compatibility with Arduino simplifies use, while its waterproof probe ensures reliable long-term measurement.
