The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

and breath sensor in addition to the traditional keyboard. The sensors work by sending data to an Arduino, then to a DAC which makes it an analog signal that can be read by the synthesizer.

Researchers reporting in ACS Sensors incorporated a specialized breath sensor within the fabric of a face mask to detect metabolites associated with the disease. In initial tests, the sensor ...

nanoscale sensors that in small-scale tests distinguished a key change in the chemistry of the breath of people with lung cancer. November is Lung Cancer Awareness Month. People breathe out many ...
