    Need to measure water quality and other parameters but haven’t got any low-cost pH meter? Find it difficult to use with Arduino? DFRobot analog pH meter, specially designed for Arduino controllers and has a convenient and practical “Gravity” connector and a bunch of features. Instant connection to your probe your Arduino to get pH measurements at ± 0.1pH (25 ℃). For most hobbyists, this great accuracy range and its low cost make this a great tool for biorobotics and other projects! It has an LED that works as the Power Indicator, a BNC connector, and a PH2.0 sensor interface. To use it, just connect the pH sensor with the BND connector, and plug the PH2.0 interface into the analog input port of any Arduino controller. If pre-programmed, you will get the pH value easily. Comes in a compact plastic box with foams for better mobile storage.

    Build your own PH meter gadget or a water monitoring station for your water tanks. This and our other water sensor devices could make for the ultimate water control device. Use it for your aquaponics or fish tanks or other materials that need measurements.
