Gravity - pH analog sensor/meter V2 - 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).

Arduino compatible product

For a sample code and detailed information, see theuserguide.

The sensor works with any microcontroller equipped with analogue inputs, including Arduino. In order to read the data, simply connect the power supply and output pin to any analogue input of the microcontroller and read the measurement result.
