Meteorologists consider several factors when forecasting humidity, but the two most common are relative humidity and dew point. Both have advantages when it comes to communicating just how humid ...

A fast response relative humidity (RH) sensor with a fiber tip pentaerythritol tetraacrylate (PETA) based all-polymer microcavity is presented. The fiber tip all-polymer microcavity, with a maximum ...

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 ...

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, ...

Note. A compact analogue reflectance sensor such as the CNY70 was not used in the Arduino Uno experiments described. Instead, a homemade sensor was assembled using a single infrared LED (IR333C) and a ...

Relative humidity (RH) is the amount of moisture in the air as a percentage of the amount the air can actually hold. Warmer air can hold more moisture than cooler air, which means that for a given ...

New optical sensor using differential guided-mode resonance achieves record sensitivity and portability, enabling real-time ...

The standard instrument for the measurement of rainfall is the 203mm (8 inch) rain gauge. This is essentially a circular funnel with a diameter of 203mm which collects the rain into a graduated and ...
