Reports

This is the main section of this site. Sensor and Datasheet reports should be linked off this page. Format your link like this:

[[Reports.SensorName | Title of the Report]] - Short description, if necessary -[[~yourLogin]]

  • "Reports.SensorName" creates a new page for our report in the Reports group of the wiki.
  • The "~yourLogin" tildes (~) at the end automatically adds a link to your profile.

Any code samples or glossary entries should linked within your main Report on a separate page in the Code and Glossary groups. They will automagically show up in the Code Samples and Glossary sections of the site if you do this. Please sign and describe your code samples in the first 7 lines of the page.

Link them in your report like this:
[[Code.CodeSampleName | Title of code sample]]
[[Glossary.GlossaryEntryName | Term you are defining]]


A Sample Report -- tigoe , jamie & Jeff


Biometrics

  • Biometrics System Final Report. "Biometric technologies are defined as "automated methods of identifying or authenticating the identity of a living person based on a physical or behavioral characteristic." This report gives an overview of biometric technologies, and an example of rudimentary face rcognition using Max/MSP and the cv.jit objects. Original report by Saranont Limpananont
  • Reflective Optical Sensor There are many ways to detect heart rate, whether through electropiezo pulsation monitoring, chest-strap heart contraction detection or photoplesmography. The most wearable and continuous detection method for detecting via a user's wrist is by using a reflective optical sensor that sends an IR signal against the wrists arterial vein and reflects that to a phototransistor that catches the amount of light being sent. Full report of the TCRT1000 and an application of detecting HR from the wrist. Aislinn Dewey

Here's a heart rate example from Justin Downs using an LM358 op amp

Safety and Alarm ICs


Electrochemical Sensors

  • pH and Conductivity meter I used pH and Conductivity meter for urinalysis. It measures both pH(a level of liquid's acidity or alkalinity) and conductivity(a measure of a material's ability to conduct an electric current) at the same time. Original report by YiSeul Park


Tilt, Acceleration, Position, and Orientation sensors

Gyrometers

Compasses



Accelerometers Accelerometers are simple MEMS (Microelectromechanical System) devices and are used to measure position, motion, tilt, shock, vibration, and acceleration (the rate of change of velocity). They are available with one, two, or three axes.


Tilt Sensors


GPS receivers


Angle Sensors


Environmental Sensors


Touching, Pushing, Pulling Sensors

Capacitive Touch Sensors


Force Sensing Resistors


Flex Sensors

  • Flex Sensors The following flex sensors are tested and reported on here: the Spectra Symbol Flex Sensor, the Gentile brand that's available at Jameco and the bookstore, and the Flexpoint Bend Sensor. Original report by Rebecca Bray.


Stretch and Strain sensors


Vision, Light, Color Sensors


Gas, Liquid flow, pressure sensors


Acoustic Sensors

  • LDTM-028K Piezo When the piezo film is bent from the mechanical neutral axis, a very high strain within the piezo polymer is created and generates a high voltage. Original report by Erin Kim
