“…Some of these techniques include ultrasonic, passive infrared, laser radar, impulse radar, frequency modulated-continuous wave (FMCW) radar, capacitive and video-based vision [7]. Ultrasonic and infrared sensors find many applications in mid-range distance measurements [8]. Ultrasonic sensors allow for detection of even small and hard to sense obstacles such as tree branches or cables at high frame rates, as well as see-through obstacles such as windows [9].…”

“…Ultrasonic sensors work by measuring the time of flight of sound energy of a short burst with the transmitter and receiver separated [7,8]. The transmitter converts electrical signals into ultrasound while the receiver converts the reflected ultrasound into electrical signals.…”

“…The echo patterns received by the sensor's receiver are then compared with the patterns of sound waves to determine detected signal's condition. The distance to an object is determined by measuring the time taken from the point a pulse is transmitted to the point the reflection is received [7,8,10]. Ultrasound technology has been used in a number of studies with varied outcomes.…”

Obstacle detection is a challenging problem that has attracted much attention recently, especially in the context of research in self-driving car technologies. A number of obstacle detection technologies exist.Ultrasound is among the commonly used technologies due to its low cost compared to other technologies. This paper presents some findings on the research that has been carried out by the authors with regard to vehicle driver assistance and profiling. It discusses an experiment for detection of obstacles in a vehicle driver's operational environment using ultrasound technology. Experiment results clearly depict the capabilities and limitations of ultrasound technology in detection of obstacles under motion and obstacles with varied surfaces. Ultrasound's wavelength, beam width, directionality among others are put into consideration. Pros and cons of other technologies that could replace ultrasound, for instance RADAR and LIDAR technologies are also discussed. The study recommends sensor fusion where several types of sensor technologies are combined to complement one another. The study was a technical test of configurable technology that could guide future studies on obstacle detection intending to use infrared, sound, radio or laser technologies particularly when both the sensor and obstacle are in motion and when obstacles have differing unpredictable surface properties.

“…When IR light falls on the photodiode, its resistance and correspondingly, its output voltage, change in proportion to the magnitude of the IR light received. This is the underlying principle of working of the IR sensor [9]. There is an onboard micro-SD card slot, which can be used to store files for serving over the network.…”

In the present day scenario, we see that the Dumpster or Dust bin placed in the cities is overflowing due to increase in the waste. It causes unhygienic condition and leads in spreading deadly diseases & human illness, to avoid such a situation we are planning to design "Dumpster Monitoring System". In this proposed system each dumpster contains an embedded device to track the level of the garbage in the dumpster and unique ID will be provided to easily detect which dumpster gets filled. The embedded device consists of IR Sensor, Arduino Uno and Arduino Wi-Fi Shield. Once the level gets filled it will transmit the level of the garbage with the unique ID through the mobile application. The notifications are accessed by the concern authorities through the internet and they can take immediate actions to clean the dumpster.

“…In this study the ultrasonic sensor is used to detect the obstacles [19,20,21,22] and GPS is employed for positioning and navigation in the wayfinding process. This type of ultrasonic sensor measures the interval between sending waves and receiving the echo signals with respect to the speed of sound in the environment to estimate the distance to the obstacles.…”

ABSTRACT:The blind and visually impaired people are facing a number of challenges in their daily life. One of the major challenges is finding their way both indoor and outdoor. For this reason, routing and navigation independently, especially in urban areas are important for the blind. Most of the blind undertake route finding and navigation with the help of a guide. In addition, other tools such as a cane, guide dog or electronic aids are used by the blind. However, in some cases these aids are not efficient enough in a wayfinding around obstacles and dangerous areas for the blind. As a result, the need to develop effective methods as decision support using a non-visual media is leading to improve quality of life for the blind through their increased mobility and independence. In this study, we designed and implemented an outdoor mobile sensor-based wayfinding system for the blind. The objectives of this study are to guide the blind for the obstacle recognition and the design and implementation of a wayfinding and navigation mobile sensor system for them.In this study an ultrasonic sensor is used to detect obstacles and GPS is employed for positioning and navigation in the wayfinding. This type of ultrasonic sensor measures the interval between sending waves and receiving the echo signals with respect to the speed of sound in the environment to estimate the distance to the obstacles. In this study the coordinates and characteristics of all the obstacles in the study area are already stored in a GIS database. All of these obstacles were labeled on the map. The ultrasonic sensor designed and constructed in this study has the ability to detect the obstacles in a distance of 2cm to 400cm. The implementation and the results obtained from the interview of a number of blind persons who employed the sensor verified that the designed mobile sensor system for wayfinding was very satisfactory.
