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 ...

Abstract: This paper describes the use of multiple Infrared sensors to reconstruct a shape by detecting any changes in sensor displacement when there is an obstacle placed in front of the sensor.

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 ...

In the shadowy realm of nocturnal hunting, snakes have evolved one of nature’s most remarkable adaptations: the ability to “see” heat. Unlike humans, who become virtually blind in darkness, certain ...

Robotic grippers are widely utilized in industrial manufacturing, but object slippage during assembly poses challenges, including potential damage, delays, and increased costs. Therefore, early slip ...

Designed by Nova Radio Labs in the US, the Novaduino Environmental Sensor Kit is an Arduino-programmable air quality and weather monitoring solution built around the company’s own Novaduino Display ...
