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 ...

A Raspberry Pi Pico combined with a BME280 sensor can create a small Pico Altimeter that measures data like elevation and air pressure.

Truth be told, diving down the smart home automation rabbit hole can be an expensive journey. All of these devices can set you back a few dollars, and those prices can add up quickly. Sure, there are ...

A simple optical fiber relative humidity (RH) sensor was proposed and demonstrated using a dumbbell-shaped inline Mach-Zehnder interferometer (IMZI) as a probe.

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, ...

As I've experimented and played with a lot of different sensors, I've discovered that these basic devices can be built for super cheap, and they're incredibly versatile. When you're done using an ...
