The Korea Research Institute of Standards and Science has successfully developed a high-quality compound semiconductor material for ultra-sensitive short-wave infrared (SWIR) sensors. The study is ...

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 ...

This Arduino sketch demonstrates how to control a relay using a soil moisture sensor and two potentiometers to set the minimum and maximum thresholds for when the relay should turn on or off. The ...

Abstract: Clouds often limit the ability of optical satellite sensors (such as the newly launched Gaofen-1 (GF-1) satellite in China) to observe regional soil moisture at high spatial resolutions, ...

In recent years, the emergence of sensor technologies has highlighted the key role of in situ soil moisture measurement in various hydrological, agricultural, and ecological applications. However, the ...

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 ...

Apart from outstanding self-adhesion, high stretchability, and remarkable fatigue resistance, the HPE-LiCl hydrogels possessed especially excellent antifreezing and long-lasting moisture performances ...
