Has an ATmega328 with Arduino bootloader, a dual H-bridge and additional prototyping space and headers. It is compatible with many shields, though four digital pins are used when operating the motor controller. Has an onboard voltage regulator, additional LEDs, a temperature sensor, and a light sensor. Part of the DFRobotShop Rover kit ...
Photoresistor. A photoresistor (also known as a light-dependent resistor, LDR, or photo-conductive cell) is a passive component that decreases in resistance as a result of increasing luminosity (light) on its sensitive surface, in other words, it exhibits photoconductivity. A photoresistor can be used in light-sensitive detector circuits and ...
Intelligent street lighting. Intelligent street lighting refers to public street lighting that adapts to movement by pedestrians, cyclists and cars in a smart city. [ 1] Also called adaptive street lighting, it brightens when sensing activity and dims while not. This is different from traditional stationary illumination, and that which dims on ...
A passive infrared sensor ( PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors. PIR sensors are commonly used in security alarms and automatic lighting applications. PIR sensors detect general movement, but do not give ...
Arduino ( / ɑːrˈdwiːnoʊ /) is an Italian open-source hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices. Its hardware products are licensed under a CC BY-SA license, while the software is licensed under the GNU Lesser ...
Electro-optical sensor. Electro-optical sensors are electronic detectors that convert light, or a change in light, into an electronic signal. These sensors are able to detect electromagnetic radiation from the infrared up to the ultraviolet wavelengths. [ 1] They are used in many industrial and consumer applications, for example:
The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller (MCU) and developed by Arduino.cc and initially released in 2010. [ 2][ 3] The microcontroller board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other ...
Back-illuminated sensor. A back-illuminated sensor, also known as backside illumination ( BI) sensor, is a type of digital image sensor that uses a novel arrangement of the imaging elements to increase the amount of light captured and thereby improve low-light performance. The technique was used for some time in specialized roles like low-light ...
