Learn how to create a simple heart rate monitor using an Arduino Pro Mini, PulseSensor, and OLED display. This ...

In this study, we demonstrate fabrication of an evanescent wave fiber optic humidity sensor based on PEG-PMMA microsphere film as moisture-sensitive material. A three dimensional stacking structure of ...

An ultra-sensitive optical fiber humidity sensor based on an extrinsic Fabry-Perot interferometer is proposed and experimentally demonstrated in this paper. The Fabry-Perot cavity is constructed by a ...

Circuit and Working Fig. 2 shows the circuit diagram of the humidifier. The system is built around an Arduino Uno (MOD1), a 5V SPDT relay module, a humidity sensor (DHT22), an ultrasonic humidifier, ...
