Just last year, we reported on the SparkFun Air Quality PM1/PM2.5/PM10 Sensor, based on the Bosch BMV080 fanless air-quality sensor and priced at around $65. DFRobot has now launched a low-cost ...

In our everyday lives, environmental conditions like temperature and humidity can have a big impact, whether it’s in your home, office, greenhouse, or server room. Imagine leaving your room for a few ...

Before we dive into how IR sensors work, let’s first get a quick understanding of what infrared radiation is. Infrared (IR) radiation is a type of invisible electromagnetic energy with waveforms ...

Electro-optical detectors are used to measure or sense the radiation emitted or reflected by objects within the detector’s optical field of view (FOV). Passive systems operate without any illumination ...

A do-it-yourself thermal imager, compatible with the FLIR Lepton 2.5, 3.1R and 3.5 sensor with Arduino firmware ...

Researchers developed a type of infrared photodiode that is 35% more responsive at 1.55 m, the key wavelength for telecommunications, compared to other germanium-based components. Detecting infrared ...

Detecting infrared light is critical in an enormous range of technologies, from remote controls to autofocus systems to self-driving cars and virtual reality headsets. That means there would be major ...

LG Innotek (CEO Moon Hyuksoo) announced on December 23 the development of a “Automotive RGB-IR In-Cabin camera module” equipped with a five-megapixel RGB (red, green, blue)-IR (infrared) sensor. This ...

Arduino Nicla Sense Env is a new sensor module with temperature, humidity, and gas (TVOC, NO2, O3) sensing that follows the launch of the Arduino Nicla Sense ME (Motion & Environment) module over ...

We all know that feeling: you've turned the lights off and are almost asleep when you hear that infamous buzz. A mosquito is hunting in your bedroom. The dance commences. You could turn on the lights, ...

While a mosquito bite is often no more than a temporary bother, in many parts of the world it can be scary. One mosquito species, Aedes aegypti, spreads the viruses that cause over 100,000,000 cases ...

If you're into robotics or electronics, you've likely come across Arduino—a small microcontroller that can control sensors and motors for nifty DIY projects. Like the Raspberry Pi, the Arduino is ...
