In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...
Abstract: Long-term drift is widely recognized as a key challenge in gas sensing systems, undermining the reliability and accuracy of these systems over time, as the pattern recognition systems lose ...
Abstract: This study uses tin disulfide (SnS2) powder with a micro-electromechanical system (MEMS) structure to fabricate a microsheet (micro-Ss)/MEMS gas sensor. The SnS2 powder assumes a 2-D ...
