SENSOR SYSTEM
MYSTICAL COMPUTER ENVIRONMENTS
A Mystical, interactive, aesthetic, computer experience.
The Sensor System was used as part of Padgett’s artist-in-residency at Loughborough University with the C&CRS for COSTART, partly funded by the EPSRC Grant GR/M14517 Studies of Computer Support for Creative Work, Artists and Technologists in Collaboration.
8 sensors are located on each side of a 365cm x 365cm frame at 30cm high. The frame is in front of a screen 245cm wide and 180cm high. One person rotates the shape and chooses the colour, one person walks in the frame and extrudes smaller basic shapes.
When people move in the installation squares are generated in the axis they move. Rotation is added and intergalactic patterns result.
This interactive work breaks down the subject/object dualisms as the participant is also the work. Participants move around a sensor system to produce moving abstract designs that are purely aesthetic and join 2D design with a 3D, mystical, inner space.
Shot of the tachometer sensor setup in the bilges of my steamboat. There's some speculation that the bent brass support may have interfered with readings at some speeds. Tests were going to happen on the second day but a battery wire failure was unfixable without a soldering gun, conveniently left behind! Next week: bench tests with an oscilloscope.

Pyroelectric sensor is a kind of sensor, also known as human body infrared sensor, used for life burglar alarm, visitor notification, etc., the principle is to release the charge through the amplifier into a voltage output.
The piezoelectric ceramic dielectric can maintain a polarization state after being polarized, which is called spontaneous polarization. Spontaneous polarization decreases with increasing temperature and the temperature drops to zero at the Curie point. Therefore, when the material is exposed to infrared radiation and the temperature rises, the surface charge will decrease, which is equivalent to releasing a part of the charge, so it is called pyroelectric. The discharged charge is converted to a voltage output by an amplifier. This is how the pyroelectric sensor works.
When the radiation continues to act on the pyroelectric element and its surface charge is balanced, the charge is no longer released. Therefore, the pyroelectric sensor cannot detect constant infrared radiation.
Working principle: The human body has a constant body temperature, generally at 37 degrees, so it will emit infrared rays with a specific wavelength of about 10UM. Passive infrared probes work by detecting infrared rays of about 10UM emitted by the human body. The 10 UM infrared rays emitted by the human body are enhanced by the Philippine filter and collected on the infrared sensing source. The infrared sensing source usually adopts a pyroelectric element, which loses the charge balance when receiving the temperature change of the infrared radiation of the human body, and discharges the charge outward, and the subsequent circuit can generate an alarm signal after being detected and processed.
Pyroelectric effect: When some crystals are heated, an equal number of oppositely charged charges will be produced across the crystal. This phenomenon of polarization due to thermal changes is called pyroelectric effect.
Fresnel lens: According to the Fresnel principle, the Fresnel lens is divided into two types: refractive and reflective. Its role is to focus and refract (reflect) the pyroelectric infrared signal on the PIR. Second, the detection area is divided into a number of bright areas and dark areas, so that moving objects entering the detection area can produce a modified pyroelectric infrared signal on the PIR in the form of temperature changes, so that the PIR can generate a change electrical signal. The sensitivity of the pyroelectric human body infrared sensor (PIR) is greatly increased.
This is a work of art.
The running loop sensors are set into the path inside a custom built chamber. The cables run down the slope (left) and link to a display monitor.
When the weather warms, and the Macadam cures, the surface of the path will be coated with red running track paint. Two lanes will also be marked out.
In between the covers marks the finish of the 50m sprint straight and the start of the running loop.

A motion sensor is typically used in large areas or as a second line of defense -- the best defense against burglars is placing sensors on all accessible doors and windows.

This has been edited to show the spots best, not show the scene I intended to capture. My sensor is absolutly littered with spots, I counted like over 40 and some really big. eBay X-e2, 3 weeks old to me. Probably should learn how to clean a sensor anyway but this seems pretty bad? :(
The Global Motion Sensors Market size is expected to reach $8.8 billion by 2025, rising at a market growth of 8.2% CAGR during the forecast period.
Motion sensing is an emerging technology that is transforming how machines interact with a human. While the technology majorly finds application in infotainment, with recent innovations, it has successfully penetrated routine household activities and other settings. The rising applications of motion sensors in the consumer electronics and automotive industries have been considerably boosting the market for motion sensors. An increase in the demand for high-end MEMS accelerometers within the industrial and defense applications are boosting the market growth. These applications may include structural health monitoring for bridges, inertial measurement units for navigation and oil exploration. However, the high cost of detectors and the introduction of inexpensive and low-quality detectors in the motion sensor market may restrain the growth of the market. Despite the restraining factors, growing advancements in technology and novel innovations in motion detectors with their growing applications are creating various opportunities for market expansion.

De l'11 de maig al 9 de desembre de 2012
Inauguració: 10 de maig de 2012, 19.30 h
ExpoCambra
“Ænvers Girona_Mapes intangibles” és la primera edició d’un programa del Bòlit que té com a nucli de reflexions i operacions la ciutat de Girona. Aquest primer episodi, comissariat per Flora Bacquelaine, és un exercici que pren la cartografia com a mètode d'investigació urbana i el mapa com a instrument de comunicació. Es tracta d'una reflexió sobre la contemporaneïtat gironina a partir de diferents aproximacions.
First test of the proximity sensor for the exhibition "Ningen Dog Disco".
When someone stands close to the proximity sensor for more than 1s., the Arduino launches a pattern of lights (in the final version, it will be bulb lights).
