This paper presents the design and validation of a pH measurement IoT system for Precision Agriculture applications. The system is based on an IoT architecture which consist on: data acquisition and processing, information centralization and access to users. Designing each of the components of these modules is described and shown experimentation process to validate the operation of this system. With a -0.058V slope for pH measurement and mean squared errors in the field tests of 0.0420, 0.067 and 0.0011 for pH 3.9, 7 and 9.1 respectively, it is demonstrated the ability of the system to perform measurements at multiple points in large areas.
