Ammonia (NH 3)—the second-most-produced chemical globally—has proven to be highly important in furthering human civilization over the centuries, both in terms of technological capabilities and ...

Abstract: Many odors, such as poisonous and exhaust gases, are unsuitable for human detection. Therefore, techniques for predicting gas types and concentrations are essential. The metal oxide sensor ...

Abstract: This study presents a reference-free calibration method for wearable core body temperature sensors based on the single-heat-flux approach, eliminating the need for a pre-constructed dataset ...

This is a UART temperature sensor device that uses Atmega32 as it's microcontroller, along with GA2.2K3A1i(A) thermistor and simple voltage divider circuit to measure temperature at sampling frequency ...
