In winter, it’s important to ventilate living and working spaces regularly. Here’s how to make a homemade measuring station ...

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 ...

If you read about Hall effect sensors — the usual way to detect and measure magnetic fields these days — it sounds ...

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 ...

The SHT3x family of sensors should work up to 1 MHz I2C. This library should also work for SHT30 and SHT35 but these are not tested yet. Sometimes you need to control more devices than possible with ...

Abstract: In this paper, we propose a human gesture recognition algorithm using impulse radio ultra-wideband (IR-UWB) radar. The radar signal is transmitted into a three dimensional space, however, ...

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 ...
