A novel sensor solution for e-cigarettes enables smaller and less expensive MEMS sensors to now be used without false triggers
This paper explains the problems of false triggers that happen when smaller and less expensive MEMS sensors are used to replace the usual ECM sensors that detect when the user has inhaled on an e-cigarette and activate the heating element. Until now, the cause of these false triggers has been elusive. Nanusens has discovered that the smaller air passageways of MEMS-based designs clog with oils that result in potentially dangerous false triggers. Nanusens’ patented solution is explained that uses averaging algorithms on the data from an absolute pressure MEMS sensor in the e-cig and accurately identifies when the user inhales and thus prevents these false triggers.
