PH Sensor Gravity Module 


The pH meter is mainly designed for Arduino controllers and has a convenient and sensible “Gravity” connector and a group of functions. instantaneous connection on your probe and your Arduino to get pH measurements at ± 0.1pH (25 ℃). For the maximum hobbyist, this awesome accuracy range and it is low value make this a wonderful device for biorobotics and other projects! It has an LED which goes because of the electricity Indicator, a BNC connector, and a PH2.0 sensor interface. to use it, just join the pH sensor with the BND connector, and plug the interface into the analog input port of any Arduino controller.
