Abstract
In an example implementation, a substance detection method includes sensing for fluid in a chamber of a substance detection device. When fluid is sensed in the chamber, the method includes sensing again for fluid in the chamber. When no fluid is sensed in the chamber, the method includes initiating a substance detection process.
