Thermoharvesting Wireless Sensor System

Micropelt TE-CORE /RF

Introduction

1.1 System Introduction

The TE-CORE /RF is a complete thermo-powered, self-

sufficient wireless sensor node system (WSN).

The TE-CORE /RF is based on an Energy Harvesting

module with power management function, which con-

verts locally available waste heat thermoelectrically to

indefinite free electric energy.

A Wireless Sensor module is connected to the TE-

CORE /RF and is equipped with Texas Instruments (TI)

ultra-low power technology (CC2530).

A temperature difference as little as 10 ºC between a

hot surface and ambient air is enough for the TE-

CORE /RF to make a temperature measurement and a

radio transmission every two seconds.

Via an USB receiver and PC application software, infor-

mation about the thermal profile of the heat source,

the generated output power, the thermal generator

output voltage, the energy storage voltage and battery

equivalent are displayed.
