Well, looks like my sonar sensor (SRF05) is a just a tad inaccurate for precise measurement as I found from my radar screen I made ( Arduino Radar Sscreen ). So I’ve got hold of a Sharp GP2Y0A02 series infrared distance sensor . It’ll detect and measure anything within a 20-150cm range and it does this by triangulation from where it emits a beam of IR and from when it receives it – this isn’t too important to understand.
Description: This is the newest revision of our FTDI Basic .
Meet The Tacit Project. It’s Sonar For The Blind. This is a project I’m calling Tacit. No, I didn’t bother making an awkward backronym for it, it just seemed like an appropriate name that’s a lot shorter (though less descriptive) than “Hand-Mounted Haptic Feedback Sonar Obstacle Avoidance Asstance Device”.
Recently I dropped on the paper entitled “Rhythm of Life Aid (ROLA): An Integrated Sensor System for Supporting Medical Staff During Cardiopulmonary Resuscitation (CPR) of Newborn Infants” in IEEE TITB Journal . Authors present a system that utilizes various sensors and provides audiovisual feedback to physicians for exercising the Cardiopulmonary Resuscitation (CPR) on newborn infants. CRP is a crucial medical procedure for the survival of a newborn infant when complications, such as asphyxia or severe infection leading to cessation of breathing and decrease of the heart rate, exist. On one hand, improper chest compressions could cause internal injury to patients, such as rib fractures, punctured lungs, and damage to the heart, liver, or spleen.
Shoes for the Blind People? This is true, a Researchers from Hewlett - Packard Labs in Bangalore, India named Anirudh Sharma developed a shoe that is equipped with proximity sensors and vibration which is normally found in mobile phones. It would help the blind people to searching for a right direction.
No more classic old stick is needed for the blind because this is the smartest innovation in wand for the blind. It works by sensing the objects around and recognize objects by distance sensor without a pole. This stick is a useful one for blind because of its tactile sense.
Benefits of Virtual Instrumentation: The very concept of Virtual Instrumentation has made the job of design testing much easier. Now instead of managing every hardware component, ensuring their functionality and the final interconnections in the whole design, one can simply design the module on virtual instrumentation software such as LabVIEW and vary the various design parameters to get the optimum results making it highly user friendly. Also one can eliminate the need of costly devices as they can be simulated and the errors can be easily identified and rectified. Virtual Instrumentation not only makes the designing process simpler but also cheaper. Also as the concept of virtual instrumentation is based on standard commercial technologies it easily serves the masses.

Description: This is the fantastically easy to use sensor from Maxbotix . We are extremely pleased with the size, quality, and ease of use of this little range finder.
Presently, blind people use a white stick as a tool for directing them when they move or walk. Although, the white stick is useful, it cannot give a high guarantee that it can protect blind people away from all level of obstacles. Many researchers have been interested in developing electronic devices to protect blind people away from obstacles with a higher guarantee.
This paper describes the development of a navigation aid in order to assist blind and visually impaired people to navigate easily, safely and to detect any obstacles.
In past tutorials, we have covered temperature, color, time, direction, but never distance or proximity. I think I strayed away from this because most of the lower cost proximity sensors are pretty drop-dead-simple to use and thought it might not be that useful. But the time has come, I’m writing about some distance/proximity sensors. While using them is technically simple, I have 3 pretty different sensors that all have pros/cons, and none of them would make a very suitable replacement for the others, so maybe this will help you choose the right one if you find yourself in need. All 3 sensors will be outputting an analog voltage that we will be reading with our Arduino .
Wide range, low power temperature sensor outputs an analog voltage that is proportional to the ambient temperature. To use, connect pin 1 (left) to power (between 2.7 and 5.5V), pin 3 (right) to ground, and pin 2 to analog in on your microcontroller. The voltage out is 0V at -50°C and 1.75V at 125°C. You can easily calculate the temperature from the voltage in millivolts: Temp °C = 100*(reading in V) - 50
