I have recently completed a series of eleven articles on sensors for music production. These provide a thorough survey of the hardware and software available to those who wish to explore environmental input into audio systems. I developed these documents from my own research for the project "Numbers In The Dark".
The Theatre of Noise hosts the hardware articles:
The software articles are at diagrammes modernes, my blog on programming and development:
I thank the Arts Council for their support in this research.
