A decision framework reference for ISFET sensor-based electronic systems design for agriculture industry applications

A methodology for the integration of ISFET sensors in precision agriculture and digital agriculture applications is presented through this paper. The methodology, which is the result of a research process, aims to establish a clear procedure when designing electronic systems based on ISFET sensors and that allow the direct or indirect evaluation of nutrient status and pH in agricultural soils. The main objective of this document is to offer engineers, integrators and designers, and the scientific community in general a series of good practices that range from the selection of the sensors, the design of their electronic systems, calibration methods, and their subsequent integration into IoT systems.
