In infrared sensors, the semiconductor material plays a critical role in detecting light signals and converting them into electrical signals. SWIR sensors designed for advanced applications ...

The aim of this project is to develop a circuit that can count the number of people entering and exiting a room using two Infrared (IR) sensors connected to an Arduino UNO. This bidirectional counter ...

As the first metal-oxide gas sensor featuring multiple sensing elements on one chip, the SGP30 provides more detailed information about the air quality. Download all the source files and open examples ...

While microwave sensors can offer 24-hour tracking, they are most effective for identifying objects in low Earth orbit. This makes infrared detection the most reliable method for locating satellites ...

A tiling of larger-format sensors would produce an IR survey instrument with significant cost savings relative to HgCdTe-based cameras, if one is willing to forego the K band. Such a camera would be ...

Impact Statement: Nowadays, the high RI anaylte fiber sensing are mainly depend on the hollow fiber core or polishing structure, which brings in low tolerance during the future fiber fusion and ...

Abstract: this paper reports the theory, fabrication and testing of a novel uncooled infrared (IR) sensor using amorphous silicon thin film transistors (a-Si TFTs) as the active elements. The measured ...

Simultaneous and molecularly selective parts-per-billion detection of benzene, toluene, and xylenes (BTX) using a thermal desorption (TD)-FTIR hollow waveguide (HWG) trace gas sensor is demonstrated ...
