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.
Occupancy sensor types include: PIR sensors, which work on heat difference detection, measuring infrared radiation.Inside the device is a pyroelectric sensor which can detect the sudden presence of objects (such as humans) who radiate a temperature different from the temperature of the background, such as the room temperature of a wall.
InMoov is a humanoid robot, constructed out of 3D printable plastic body components, and controlled by Arduino microcontrollers. InMoov is a robot developed for artistic purposes by French sculptor Gaël Langevin [1] in September 2011. (The first blueprint files were published in January 2012 on Thingiverse. [2])
Wireless home alarm system control panel A house alarm. A security alarm is a system designed to detect intrusions, such as unauthorized entry, into a building or other areas, such as a home or school.
A motion detector attached to an outdoor, automatic light. A motion detector is an electrical device that utilizes a sensor to detect nearby motion (motion detection).Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area.
Announced on 21 January 2021, the RP2040 is the first microcontroller designed by Raspberry Pi Ltd. [1] [2] The microcontroller is low cost, with the Raspberry Pi Pico being introduced at US$4 and the RP2040 itself costing US$1.
