High-precision air quality monitors are normally very expensive, but Tim Dye of Sonoma Technology is on a mission to change that. He’s been working with Michael Heimbinder and habitatmap.org to create a low-cost sensor system that when designed properly and integrated into a software platforms can provide valid data.
AirCasting is a platform for recording, mapping, and sharing health and environmental data using Arduino and Android. It combines an Arduino with a set of sensors for air quality measurement; temperature, humidity, and carbon monoxide, nitrogen dioxide, and particulate matter. The system combines the sensors using an Arduino Uno and then sends the data to an Android app using Bluetooth. The plans are all open for modification, so you can add your own sensors as needed. A heart rate monitor and an LED vest can also be linked to the AirCasting app, providing a complete the system for realtime, wearable feedback of your body’s reaction to the environmental air quality.
There are many DIY air quality measurement projects online, but most of them are not calibrated against known standards or professional equipment. But Dye and his colleagues have tested the AirCasting particulate matter sensors against the same equipment Sonoma Technology uses for precise measurement, and they’ve gotten surprisingly good results. Correctly constructed and deployed, the AirCasting shows promise as a low-cost alternative to complement the expensive high-end air monitors.
AirCasting is a collaboration between many groups: Michael Heimbinder of habitatmap.org manages the project, and Tim Dye of Sonoma Technology consults on design, data evaluation, and field deployment; Dr. Iem Heng and Raymond Yap of the City Tech Mechatronics Technology Center designed and built the hardware; Dr. Andy Zhang designed and built the monitor casings; Valentine Leung designed and built the LED garments, and Brooke Singer has helped guided the project with a mind towards interactivity and public engagement.
The data from your AirCasting air monitor can be uploaded to the AirCasting database, which aggregates data from all AirCasting contributors, or can be sent to your own database and all the code for the project is open source and available through GitHub
The website AirCasting.org provides links to all the software and hardware plans.
Bio Circuit stems from our concern for ethical design and the creation of media-based interactions that reveal human interdependence with the environment. With each beat of the heart, Bio Circuit connects the wearer with the inner workings of their body.
Ecco un piccolo video report della puntata dell’Arduinotour a Matera (c’é anche un set su Flickr). Questa edizione del tour é stata caratterizzata dalla partecipazione di un ragazzo francese (partito dalla Bretagna e volato per un week-end a Matera – Grande Baptiste!) che ha condiviso con noi la sua esprienza di sviluppatore di open energy monitor, un framework open source per la visualizzazione di consumi online, di cui parleremo presto in una intervista ad hoc. (il blog di Arduino ha trattato precedentemente questa storia, vai al post).
Causa maltempo il workshop é stato ospitato presso le Monacelle, un bed & breakfast poco l’ontano dall’Incubatore, all’interno dei Sassi. Un grazie a Sviluppo Basilicata per il supporto e l’aiuto nell’organizzazione dell’evento.
Per chi si stesse chiedendo quando e dove si farà il prossimo workshop #arduinotour, eccovi serviti: Reggio Emilia a fine gennaio (26-27), presso il neonato Fablab ospitato all’interno dello Spazio Gerra.
Have you ever wanted a smart home that can automatically adjusts the blinds for you? If so, this project is for you.
In this instructable, the author describes his approach to “smart blinds”, by using an Arduino board, an ethernet shield, a motor shield and a couple of sensors.
By means of a simple web-based GUI, the user can manually open and close the blinds, or he/she can setup both temperature and brightness thresholds in order to automate the whole process. Finally, opening and closing events can also be scheduled at pre-defined times of the day, if necessary.
The complete tutorial, together with the source code of the project, can be found here.
We are eager to announce the launch of the official Arduino Starter Kit! We have been working hard together in developing a complete selection of 15 projects that will let you become a true arduino tinkerer!
But that’s more:
The new starter kit has been developed together with a series of ten video tutorials hosted by Arduino co-founder Massimo Banzi, which can be viewed at www.rs-components.com/arduino. Ideally used in conjunction with the videos, the kit provides an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It contains all of the essential components required to start programming with the Arduino Uno board, and a guidebook featuring 15 different projects, which are designed to evolve the user from beginner to professional level. Comprising a motor, servomotor and driver, the kit also offers particular benefits to users wishing to apply mechatronics to their designs.

Open Electronics‘ staff were looking for a common and standard hardware platform usable on different robots they were working on. Their goal was to find a single platform that had to provide power supply to the microcontroller, it had to provide stabilized voltage for the servos, and, finally, it had to be equipped with an obstacle detector and with an IR receiver.
Having chosen Arduino as the target core board, they developed an ad-hoc shield meeting all these requirements, whose detailed description can be found here, together with the BOM and a lot of source code.
