Abstract 

Here we introduce so-far the largest subject-rated database of its kind, namely, "Effect of Millet vegetation on path-loss between CC2538 SoC 32-bit Arm Cortex-M3 based sensor nodes operating at 2.4 GHz Radio Frequency (RF)". This database contains received signal strength measurements collected through campaigns in the IEEE 802.15.4 standard precision agricultural monitoring infrastructure developed for millet crop monitoring from period 03/06/2020 to 04/10/2020.

Instructions: 

Here we introduce so-far the largest subject-rated database of its kind, namely, "Effect of millet vegetation on path-loss between CC2538 SoC 32-bit Arm Cortex-M3 based sensor nodes operating at 2.4 GHz Radio Frequency (RF)". 

This proposal examines the received signal strength through measurement campaigns in the IEEE 802.15.4 standard precision agricultural monitoring infrastructure developed for millet crop monitoring from period 03/06/2020 to 04/10/2020.

Observations at different node height and vegetation depths in a crop cycle (123 days) with a sampling time of 30 minutes were made in the following two scenarios:

Scenario-1 (Database-1): Nodes of Height=52 cm are deployed and RSS measurements were collected.

Scenario-2 (Database-2): Cluster of nodes with varying height={37,51,64,72,87} are deployed and RSS measurement were collected..

 

Instructions:

Crop: Pearl millet (JBV3/JHB467)

Database-1:

Node height: 52

Plantation row spacing: 35 cm

Database-2:
