A ZigBee – based Lightweight Wireless Sensor System for measuring action potential bio signals in Agriculture IoT Applications

摘要

The deployment and integration of a low power pervasive wireless sensor system, for measuring and processing action potentials bio signals for plants, is an interesting and challenging technical task. In our experiments, we focus on measuring electrical potentials for Chrysanthemum and Sansevieria plants. We note that the wireless pervasive sensor system, for real time data collection, should be optimally designed in terms of energy and communication costs. Therefore, in our work, we design and propose an optimized ZigBee – based lightweight end to end system to measure and evaluate plant action potentials. Our system’s design functionality response results, demonstrated a significant reduction in the firmware code length, to be loaded in the microcontroller unit, potential use of 8 – bit microcontrollers with low memory capacity and reduced development costs for hundreds of measuring plant points and reduced processing and communication costs. All these results makes the system suitable for large scale use in agricultural IoT applications.
