1. Description

The dataset contains outputs from a discrete-event simulation (Python/SimPy) of a low-power IoT device. The experiments evaluate battery discharge under different load profiles and estimate the impact of photovoltaic (PV) panel sizing, both for static and dynamic energy-harvesting scenarios.

Simulated device characteristics:

The simulated device is an industrial Ultra-Wideband (UWB) localization tag developed within the LoLiPoP-IoT project. It is based on the nRF52833 microcontroller and the DW3110 UWB transceiver, supported by a TPS62840 power management IC (for a detailed specification, please see the above-cited publication). Two energy storage options are considered:



CR2032 primary lithium coin cell – capacity 2117 J (3 V–2 V)

LIR2032 rechargeable lithium coin cell – capacity 518 J (4.2 V–3 V)


In the baseline configuration, the tag transmits its location every 5 minutes, without additional power-saving optimizations. The simulation energy profile includes active and sleep states for both the MCU and the UWB module, PMIC quiescent consumption, and realistic conversion efficiency losses.

The device model serves as the basis for evaluating:



Battery discharge characteristics for primary and rechargeable cells

Sizing of photovoltaic panels for energy harvesting

Effects of dynamic power management strategies on battery life and operational latency


Battery types:



CR2032 primary cell - maximum energy capacity 2117 J

LIR2032 rechargeable cell - maximum energy capacity 518 J


Data format: <elapsed time in seconds>,<battery charge in J>

Experiment categories:



Device consumption tests - Baseline discharge curves for CR2032 and LIR2032 under constant load

4. Relation to the Publication

The original publication focuses on the design of power-efficient and green IoT devices. This dataset provides detailed information that was used to create charts in Figures 1 and 4 and Table 1. It contains:



Raw consumption profiles for two coin-cell battery types,

PV sizing analysis for a range of panel areas,

performance of a dynamic power planning strategy.


Researchers can use these data to:



Reproduce PV sizing and battery depletion plots,

compare static vs. dynamic power planning, and

potentially validate simulation setups for other IoT scenarios.
