The Degu project has been launched with the aim of providing IoT sensor design information as open source, creating an environment where it's possible to design a mesh networking based IoT system with a DIY approach.
Degu is a platform that makes it possible to design mesh networking ready IoT systems with a DIY approach. By using the available PoC kits which allow sensors and actuators to be selected as required, together with the design and development information made available as open source, it's possible to create communicating Degu sensors with a DIY approach.
Degu sensor hardware can be evaluated easily with dedicated kits.
The Degu sensor main unit - the "Degu Base Unit" - supports installing and connecting Grove modules. This allows for the addition of functionality required for the intended use by selecting from more than 200 available Seeed sensors and actuators that support the Grove system.
Basic design information such as circuit diagrams, parts lists and source code for the Degu sensors is available as open source on GitHub.
 Various types of kits and packages are available, such as the "Degu Base Unit" for evaluation and development, and the "Grove Starter Kit" containing a collection of often used Grove sensors. For more information, please contact one of the contact points at the purchase locations.
 These are modules which support the "Grove System" connector standard supported by Seeed. There is a lineup of over 200 types of sensors, actuators and connectors.
The logic for preprocessing captured sensing data can be set directly on the Degu sensor using the MicroPython implementation of Python.
Sensing data can be sent to and received from data hubs on IoT platform (AWS, Microsoft Azure etc) in JSON. As communication is in this cloud friendly message format, the flow from data acquisition to cloud application development can be established smoothly.
|Sensing||Sensors and actuators suited to the intended use can be selected and added from the Grove module lineup.|
|Communication||With communication modules supporting the Thread® wireless IP communication standard, Degu sensors support "mesh networking" where the sensors communicate with each other in a mesh. With this, it's possible to create a low power, resilient and scalable sensor network.|
|Edge Computing||The configuration and preprocessing of sensing data, such as data thresholds and sensing intervals, can be configured directly on the Degu sensors using the MicroPython implementation of Python. As data is uploaded to the cloud after the preprocessing, this allows data collection to be done efficiently.|
|Security||With the A71CH Plug & Trust secure element from NXP, encryption keys for uses such as unit authentication are stored securely.|
 For mass production, it's possible to make use of the "Degu Mass Production Design Service", where boards are redesigned while keeping the same makeup.
With the "Degu Mass Production Design Service" available via Core Staff, Seeed will redesign prototyped Degu sensors and also take care of manufacturing and kitting according to your requests.
With this service, a case can be selected from multiple types that have been prepared in advance. Smaller types around the size of a matchbox or lighter are available, so it's possible to use the sensors and actuators selected from the Grove module range during prototyping as-is, while still achieving miniaturization and single-board products.
The results of the PoC work with the dedicated kits can be utilized as-is and brought through to the preparation for mass production, so it's possible to undertake mass production speedily and easily even for those without much experience in this area.
How about adding an IoT option to your cloud service?
Using Degu, you could add value through new services such as starting a service that performs situational monitoring and data collection by just connecting a gateway and sensors.
It's possible to develop and mass produce IoT devices suited to individual projects.
By taking the Degu scheme and utilizing it as a platform on individual projects, it'll be possible to then apply acquired knowhow to effectively offer further proposals for other IoT systems.
How about making your sensors easier to use?
With Degu, the end user will be able to reach development and production of the final product more easily, which could contribute to increasing the market size for your sensors.
It's easy to get started with Degu in just three steps.
See "Supported Products & Services" for purchasing the products needed for evaluation with Degu.
The Degu project is operated based on the technical cooperation of the following companies.
