Analog TDS Meter Probe Water Quality Sensor Module

This is a TDS Meter Probe Water Quality Monitoring Sensor Module.  It can be used to test the quality of domestic water, hydroponic water, and other types of water. This product accepts 3.3 ~ 5.5V wide voltage input and outputs 0 ~ 2.3V analog voltage, making it compatible with 5V or 3.3V control systems or boards. It can be used to determine the TDS value of water and, thus, the cleanliness of the water. 

Features

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