How to use an Arduino microcontroller to sense invisible electromagnetic fields using wire, a resistor, and a LED.



Aaron ALAI's EMF detector project is awesomely simple to make and fun to use. An upgraded version can be built using an LED bargraph for more 'meter-like' functionality.

Nokia developed a visionary design concept that will help user stay connected to friends as well as to the health and local environment, sharing the environmental data the sensing device collects and view other users’ shared data.


The concept consists of a wearable sensor unit which can sense and analyze environment, health, and local weather conditions, and a dedicated mobile phone.
The sensor unit will be worn on a wrist or neck strap made from solar cells that provide power to the sensors.
The users will be able to choose which sensors they would like to have inside the sensing device transforming it as a “personal trainee” if they were to choose a heart-rate monitor and motion detector (for measuring your walking pace).

Per chi svolge attività sportive all’aperto, o per chi soffre di problemi respiratori o semplicemente per chi ci tiene a respirare dell’aria che non sia troppo inquinata sarebbe utile avere un misuratore portatile della qualità dell’aria.

Ho realizzato questo grafico dinamico per visualizzare i dati giornalieri di rumore rilevati dal balcone del mio appartamento in una zona poco trafficata (non sembrerebbe) di Mestre (VE).
L'applicazione in .php genera grafici sui picchi, aggiornati in intervalli di cinque minuti per data e per client ID, in modo da poter monitorare la situazione in tempo reale e giorno per giorno.

The near future of participatory sensing on everyday mobile phones.



participatory sensing. urban sensing is about people like you—equipped with today’s mobile + web technology—systematically observing, studying, reflecting on, and sharing your unique world. through discovery and connected participation, you can see the world anew.

Uno dei progetti più interessanti che ha integrato scienza, coscienza ambientale e arte è stato PigeonBlog, di Beatriz da Costa, con la partecipazione di Cina Hazegh e Kevin Ponto.
