Product description: Gravity - Analogue V2 sensor / pH meter - DFRobot SEN0161-V2

Sensor / pH meter withanalogue output. Allows to test the level of acidity and alkalinity of aqueous solutions. Measurement accuracy is +/- 0.1 pH, which issufficientfor most applications. Equipped with LED, BNC connector and PH2.0 interface, 4 pH buffer solutions are also included in the set.A cable adapted for DFRobot IO ExpansionShieldis included.

The module is powered from 3.3 V to 5 V. The library works with two calibration methods and automatically identifies two types of buffer solutions (4.0 and 7.0).
