An approach for training of temperature cycled metal oxide semiconductor gas sensors to monitor food quality is presented. A setup including various gas sensors and a GC-MS is used to measure the ...
The gas sensor, based on a p–n heterojunction structure, was fabricated by vertically stacking a nanometer-thick layer of p-type cobalt phthalocyanine (CoPc) on a solution-processed n-type ...
This study describes two biosniffers to determine breath acetone and isopropanol (IPA) levels and applies them for breath measurement in healthy subjects and diabetic patients. Secondary alcohol ...
A self-actuating and detecting (SAD) circuit loop that drives a micro-cantilever in a gas sensor, in which the resonance frequency shifting of the beam is monitored to detect its mass change caused by ...
Build a simple LPG gas leakage detector using Arduino and MQ-5 sensor. This beginner-friendly project features buzzer and LED alerts, circuit diagram, and complete Arduino code for home safety.
