Helium leaks are hard to detect. Helium is odorless, colorless, tasteless, and does not react with other chemical substances. Not only can we not see or smell it, but traditional gas sensors have ...

Researchers at Nanjing University have developed a novel helium-detecting device, drawing inspiration from the traditional Japanese bamboo weaving technique, "Kagome-biki." Their findings were ...

Here’s a fun build from [RootSaid] that is suitable for people just getting started with microcontrollers and robotics — an Arduino-controlled two-wheeled robot. The video assumes you already have one ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...

While fluorophore-biomacromolecule systems are relatively well known, afterglow luminophore-biomacromolecule conjugates/complexes are rarely studied. Here, the authors report the development of a ...

Abstract: A novel radar sensing system for non-contact and continuous detection of heart sound is proposed in this paper, which is a custom designed 120 GHz interferometric radar. The moving ...

This research is aimed to explore the efficacy and comparison of low-cost light sensor measurements for agricultural applications. For this reason, TSL2561, BH1750, and TEMT6000, low-cost light ...

Currently your Arduino can only beep like a microwave oven. Mozzi brings your Arduino to life by allowing it to produce much more complex and interesting growls, sweeps and chorusing atmospherics.

Abstract: The massive quantity of electricity gets used in lights through roadways in India. Still, roadways remain empty for nearly all of the day after at night, with a handful of cars passing ...
