11. Identify the value of your data?
2020/10/19 - How to develop an IoT Solution – Louis Moreau
Identify new
opportunities
Can you trade the data?
Can you develop new
solutions with your data?

experience
Helps customer to feel better /
safer?
Reduces shipping time?
Cost optimization
Helps you to reduce costs?
Helps you to predict failures?

12. From the prototype to an industrial product
Device Development
2020/10/19 - How to develop an IoT Solution – Louis Moreau

13. Is the device already exist on the market?

14. From the prototype to the product
Functional prototype
Use development boards or building blocks:
- Arduino
- NodeMCU
- Rapsberry
- STM32 Kits
- etc…
Use standard casing
2020/10/19 - How to develop an IoT Solution – Louis Moreau
Technical Prototype
Use microcontrollers
- ARM Cortex M0 to M3
- ESP82266 or ESP32
- AVR
Use solder boards to assemble your components
Use 3D printing for the casing

15. How to design your hardware
2020/10/19 - How to develop an IoT Solution – Louis Moreau
Autonomy
Impacts the volume, the ability to
communicate, the production cost of the
object
1 2 3 4 5
Communication Protocol
Impacts the design of the object, its size
and energy consumed.
Size
The size of the object directly affects the
autonomy but also the choice of the
case and the radio quality achievable.
The functions performed
Directly impact energy consumption
through the use of sensors but also the
frequency of communication.
Investment in industrialization
Impacts the unit cost of production and the
choices in terms of design and materials

Security
Physical & Data transport

16. Casing
2020/10/19 - How to develop an IoT Solution – Louis Moreau
Completely depends on the use case
• IP XX ? IK X ?
• Size ?
• Battery impacts the casing a lot
But a few advices:
• Plastic is always better for radio than metal
• Consider shelf casing
• Don’t aim for the smallest, aim the use case!

18. Communication Protocols
The 3 fundamental elements of an IoT network
Each network has its strengths and weaknesses.
However, each technology can be considered based on
three criteria:
• Its energy consumption
how much energy consumed to send 1 MB.
• Its bandwidth
how long it takes to send 1 MB.
• Its range
over how many meters or kilometers the connection
remains reliable.

24. How to perform in managing your data?
Handle data variety
Parse your IoT Payload and store them
using standards
See: https://www.w3.org/TR/wot-thing-
description/ or
https://iot.mozilla.org/wot/
1 2 3 4 5
Ingest your data in a ML context
Detect anomalies using ML algorithms,
feed your DL models with new and
accurate data to boost your
performances
Edge Processing
Pre-process the real world data and
send only what can be valuable.
Use meta-data in your data lake (such as
timestamp, weather information or
device location not sent by the devices)
Manage your device fleet
Data coming from IoT systems can
change over time due to events such as
firmware upgrades, property of the
devices changing from one customer to
another. Address the device
management can be a pain.
Real Time monitoring and alerting
The data management solution should
also provide alerts in case any issues
arise during the process.
