Adafruit Industries is an open-source hardware company based in New York, United States. It was founded by Limor Fried in 2005. [ 3 ] The company designs, manufactures and sells electronics products , electronics components, tools, and accessories.
An infrared detector is a detector that reacts to infrared (IR) radiation. The two main types of detectors are thermal and photonic (photodetectors). The thermal effects of the incident IR radiation can be followed through many temperature dependent phenomena. [2] Bolometers and microbolometers are based on changes in resistance.
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.
Limor Fried is an American electrical engineer and owner of the electronics hobbyist company Adafruit Industries.She is influential in the open-source hardware community, having participated in the first Open Source Hardware Summit and the drafting of the Open Source Hardware definition, and is known by her moniker ladyada, an homage to Lady Ada Lovelace.
A thermal sensor is a device able to detect the thermal radiation emitted by an object located in the FOV(Field Of View) of the sensor. Infrared radiation ( IR ) striking the sensor produces a change in the temperature of the device that as a consequence generates an electric output signal proportional to the incident IR power.
If the remote control to be used is also IR-based, there must be an IR sensor within its line of sight that will relay signals to the IR blaster over a wire or radio. The output of an IR blaster (like that of any infra-red remote) is invisible to the human eye because its wavelength is beyond the range of visible light.
The rapid increase in satellites and space junk will make low Earth orbit unusable unless companies and countries cooperate and share the data needed to manage that most accessible region of space ...
The systems use an effective method of jamming infrared missile seekers through the sensor aperture and can be placed in either active or standby mode. In the standby mode, the aircrew must select the active mode to begin jamming infrared (IR) threats. The pulsing flashes of IR energy confuse the missile guidance system, preventing the tracking ...
