Introduction to Energy Harvesting

There is an Ocean of Energy all around us

This is where EnOcean got its name

The Concept of energy harvesting is not new

Michael Faraday discovered the operating principle of electromagnetic

generators 1832. The principle, later called Faraday's law, is that an

electromotive force is generated in an electrical conductor that

encircles a varying magnetic flux. This principal can use water to drive

a dynamo and generate power

Windmills used wind to convert ambient energy to mechanical force

NO information about application logic

Devices with same EEP can work “Push ‘n Play”

.. is described by RORG + FUNC + TYPE (= EEP#) RORG = Protocol type (RPS, 1BS, 4BS, VLD)

FUNC = Device function (e.g. Room Thermostat)

TYPE = Properties set (e.g. Temperature and Humidity)

EnOcean Equipment Profiles Learn Telegram from a 4BS sensor

The EEP (EnOcean Equipment Profile) is an agreed telegram profile

number that points to an interpretation table needed in the receiver.

To keep the radio telegram as short as possible the sensor will inform the

receiver during the teach-in procedure about its characteristics.

For interoperability a standard for this teach-in procedure and for the later

exchange of data has been defined.

Attainable power from thermoelectric converters depending on size and temperature difference

Thermal Energy (1)

PELTIER / SEEBECK effect

A thermoelectric device creates a voltage

when there is a different temperature on 2

junctions of 2 metals, a property discovered

by Seebeck in 1821.

Conversely when a voltage is applied, it creates

a temperature difference (known as the Peltier

effect).

There are a number of low cost Peltier

elements available and these can be used ‘in

reverse’ as generators for small wireless

monitors.

Harvesting Heat

Heat

Cold ( heat sink)

N P - +

A heat source will drive electrons

in the n-type element toward the

cooler region, creating a current

through the circuit.

Holes in the p-type element will

then flow in the direction of the

current. The current can then be

used to power a load.

+ -


Kurukshetra 13

The voltage generated from Peltier

elements are very low requiring

innovative DC-DC conversion

The ECT310, is a low-cost ultra low

voltage DC/DC converter that uses a

highly innovative blocking oscillator

design.

2+ Kelvin temperature difference on the

Peltier device gives around 20 mV to 50

mV corresponding to an output voltage

range between 3V to 4 V from the ECT

310.

Designing external sensors / electronic circuits, key requirements:

1. Ideally passive sensor types (e.g. thermistor, photo-resistor, not always possible!) 2. Device operating voltages (IF APL.) as low as possible, e.g. 1.8 V or lower 3. Totally operating current as low as possible, e.g. <1 mA or less (nA…µA) 4. Short measurement time (default sensor settling time e.g. <2 ms after power-up)

EnOcean devices: some important design hints

Radio propagation range considerations, key element antenna:

1. Indoor propagation, energy requirements, frequencies, compliance, link budget, 2. Environment analyze, installation, antenna choice, design, verification, tools 3. Interference effects: e.g. power supply importance, rules for clean layout

1. Energy harvesting sources / availability: solar, thermal, movement: devices, limits 2. Energy storage elements: requirements, specifications, limitations, alternatives 3. Energy balance: importance of the application specific wake-up settings 4. Energy management recommendations, approaches, technological limitations

Session 4 EnOcean Starter Kit

ESK 300 - the ideal entry to EnOcean technology

EnOcean Starter Kit is the entry level product to demonstrate EnOcean’s energy harvesting and ultra low power radio technology.

ESK 300 contains a USB 300 gateway and the DolphinView Basic license to visualize EnOcean telegrams

PTM 200 push-button switch and STM 330 temperature sensor will show pre-integrated products.

ECO 200, PTM 330 housing example to demonstrate how the devices can be used.

content of EnOcean telegrams and interprets them

in relation to EnOcean equipment profiles (EEPs).

Also displayed are the reception quality of

telegrams plus transmission statistics.

DolphinView Advanced

is a software for developers and especially for

recording and debugging. Extra to the functionality

of the Basic version it can record telegrams and

analyze subtelegrams, network payload, remote

SECURITY Enhancement

Rolling Code – Fraud Resistant

against reply attack

Purpose: avoiding an eavesdropper

recording the transmission and

“unlocking” the receiver

Strategy: changing a rolling code

included in the telegram

Encryption – Tap Proof against

eavesdropper

Purpose: obscuring the information being

sent in the air

Strategy: encrypted data “unreadable”

for eavesdropper


Kurukshetra 13

Interoperable

Algorithms are public

The secret of security is the used key

Profiles will be defined for interpreting secure messages

Compatible with existing Dolphin hardware

SECURITY Benefits


Kurukshetra 13

Flexible

Different encryption algorithms selectable

Rolling code does not need to be transmitted in telegram

MAC algorithm can be selected and added

Strategies are combinable

Future proof

New algorithms can be added without breaking the concept for

Encryption

Rolling code

Message Authentication code

Strategies against new attack types can be added
