Ondes Visibles: What if the Electrosmog was Visible? #136
Dominique Guinard (Web of Things /Evrythng) tells us about an Android + Arduino application that they developed used to help people experiment with and help raise awareness around electromagnetic fields (EMFs).
It features tutorials giving you the very basics of EMFs as well as interactive experiments for low (LF) and high (HF) frequencies using home-made sensors. Basically, we plug an LF and HF sensor to an Arduino board. Then, using a USB bridge, we route the measurements to pretty much any Android mobile phone through a USB wire (using the great Microbridge library). and visualize the data in graphs.
