Sensor demonstration using ROHM Group sensors from UV light sensors to hall-effect and motions sensors. Shown at Sensors Expo, June 2011.
The solar sensor from Hobby-Boards.com has a humidity sensor, a temperature sensor and also the photodiode for solar sensor - it has been removed and the legs left for soldering the white wires to. Power is supplied to it via the two black wires ~ 12V DC unregulated. Please take good care to note the photo-diode leg closest to my thumb is the one with the tag indicating the +ve leg.
The data is transferred via ethernet cable and each device has its own ROM ID code and is polled in sequence by the weather software.
8 small blocks that formed a bigger cube, a sensorial introduction to Binomial Expansion (a +b)^2, what we learned in SPM add math.
I don't have the hinged box for this, they come in a tray.Usual wear and tear, a touch of paint will restore them to be like new.
Selling for RM30.
Wattson sensor in situ around cable between the meter and fuse box at Pages Lane. Big yellow box is the FM transmitter.

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.

Airflow and temp sensors on the air box. Looks like the airflow sensor should come out of the box with a bit of pipe still attached. Pipe is 65mm from what I can see.
how come the dust showed up only today and I hadn't removed the lenses for more than 3 months? Strange....
I believe it is not normal air dust. My guess is that this was caused by condensation. The temperature today was -15C outside and I guess that when I opened the car window to take the photos, the camera didn't react that well... oh my... gotta buy a cleaning kit.

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.

I picked up a nice, soft paintbrush at a local art store for about $10 (which, to me, is better than the 'specialty camera sensor brushes' that run for up to $100 a pop). If I were being really good, I would have washed it in isopropyl or something more appropriate to ensure there wasn't any finger oil on there... but I digress.
Using canned air, blow the bristles to both clean and charge them (static!).
Open the camera back up and wipe the brush gently across the sensor. In theory, the charged bristles will pick up most dust, so you're not really just moving dust around on it. In theory.
