Tag: ultra sonic sensor

An ultrasonic sensor is an electronic device that measures the distance of a target object by emitting ultrasonic sound waves, and converts the reflected sound into an electrical signal. Ultrasonic waves travel faster than the speed of audible sound (i.e. the sound that humans can hear). Ultrasonic sensors have two main components: the transmitter (which emits the sound using piezoelectric crystals) and the receiver (which encounters the sound after it has travelled to and from the target). [gallery ids="2125"] In order to calculate the distance between the sensor and the object, the sensor measures the time it takes between the emission of the sound by the transmitter to its contact with the receiver. The formula for this calculation is D = ½ T x C (where D is the distance, T is the time, and C is the speed of sound ~ 343 meters/second). For example, if a scientist set up an ultrasonic sensor aimed at a box and it took 0.025 seconds for the sound to bounce back, the distance between the ultrasonic sensor and the box would be about 4.2875 meters. Application of Ultrasonic sensors Ultrasonic sensors are used primarily as proximity sensors. They can be found in automobile self-parking technology and anti-collision safety systems. Ultrasonic sensors are also used in robotic obstacle detection systems, as well as manufacturing technology. In comparison to infrared (IR) sensors in proximity sensing applications, ultrasonic sensors are not as susceptible to interference of smoke, gas, and other airborne particles (though the physical components are still affected by variables such as heat). Ultrasonic sensors are also used as level sensors to detect, monitor, and regulate liquid levels in closed containers (such as vats in chemical factories). Most notably, ultrasonic technology has enabled the medical industry to produce images of internal organs, identify tumors, and ensure the health of babies in the womb. The following projects are based on ultrasonic sensor. This list shows the latest innovative projects which can be built by students to develop hands-on experience in areas related to/ using ultrasonic sensor. Mobile Robot Navigation System Through this project you will develop a robot that uses RFID (Radio Frequency Identification) tag sensors, laser range sensors and ultrasonic sensors to find its way out of a path. The robot that you build will automatically move along the path using the scanned range data till it finds a tad and then follows a pre-set map for the next movement. [gallery ids="2124"] GPS-Guided Mobile Robot The main objective of this project is to build a modular mobile robot that can navigate around its way using GPS. The primary component of this robot is its navigation system, with an augmented GPS system integrated to provide the local coordinates and help in positioning of the robot. It can be programmed to carryout multiple functionalities. Smart Walking Cane Technology can improve the quality of life of the masses. Normal people is struggle when a object is in front him but the visually challenged people still now using the blind stick, the person only able to manage the sound and the keeping the stick high on the ground and down able understand the obstacles is present or not. Pneumatic Braking System A brake is a device by means of which frictional resistance is applies to a moving machine member, in order to retard or stop the motion of a machine. Most commonly brakes use friction between two surfaces pressed together to convert the kinetic energy of the moving object into heat slow down the motion of the vehicle. [gallery ids="2123"] Automated Solar Grass Cutter Today the most promising source of energy where everyone focusing is the concept of Solar Power and its Utilization. Generally, we see people who had gardens use lawn mowers manually to cut the unwanted grass. Those lawn movers are powered from normal household’s power through cables or using petrol/diesel. Using cables creates messing problem and if there is any power cut, we can’t use that lawn mower. Similarly, if we use petrol/diesel powered machine, it requires money and they create pollution through the smoke. Through this project, you are going to build a unique Automatic Solar Grass Cutter (Lawn Mower) which is powered by solar energy and it will overcome all the above-mentioned problems.

Contact Dr. Pawan Whig Ultrasonic Distance Finder Using 8051 Today's world technology ultrasonic response is more needed like in robotics, automation. Here ultrasonic is interfacing with 8051 Microcontroller to find the range of objects. HC-SR04 is an ultrasonic ranging module designed for embedded projects like this. Drowziness Prevention and Collision Avoidance System Drowsiness is a huge problem for the drivers, especially for long-distance travelers. This has led to many accidents and deaths too, the drowsiness can be caused due to sleeping disorder, alcohol consumption, or if the driver did not have enough sleep. We cannot stop drowsiness if the driver is not physically active but we can alert the driver if he is drowsing off. [gallery ids="2122"] Collision Avoidance Robot Nowadays the robot technology is trending ,invention occurs, students are taking more interest on robotics field.This project is based on the collision avoidance robot using arduino board with ultrasonic. Ultrasonic Radar using Pi Ultrasonic sensor is used as a range finder or a distance calculator, It generates sound waves and waits for the echo and depending on the timing of the echo It calculates the distance between the sensor and the object. In this project you will be using the ultrasonic sensor to find the objects coming in the range, this project is somewhat similar to the radar, so the utrasonic sensor constantly sends sound pulses and if the sound waves are received back then there is aobject in in front of the sensor. You can create a GUI to show the area of the coverage of the sensor and if there is any object infront of the sensor you can also show the position of the object. Radar With Arduino Using Processing Software The RADAR is Radio Detection And Ranging, it consists of a transmitted radio signal aimed by an antenna in a particular direction, and receiver that detects the echoes off any objects in the path of the signal. Line Follower With Arm Robot Line following robot is a unique type of robotic system which can be used in industries. This type of robots can be used to collect the tools, carry projects and moves on the path. The sensor is used to detect the path to follow in addition, the arm to pick the objects in the path and keep it beside the path. Height Measuring Cap Nowadays we have gadgets for almost every need. This project is about a simplified method of measuring the height of a person. You will also connect the system to the internet and then update the values to the cloud using IoT. Garbage Monitoring System In this world, waste is generated from every work we do. Statistics says that about 62 million tonnes of wastes are generated from urban cities. These wastes generated from urban cities must be collected by the municipality of the city but due to some constraints this waste is not being collected on time. If the garbage is not collected regularly, it becomes a good place for breeding of the houseflies and it will make the place hard to live because it will be comprising of materials which will start to decompose and dreadful smell will be covered all over the area. Unmanned Ground Vehicle Are you interested in robotics and mechatronics? If you are an engineer with a passion for mechatronics, then you should invest in projects to gain more insight into your chosen field. Gesture Controlled Wheel chair [gallery ids="2121"] The health service industry is growing for a while now, thanks to the advancements in science and technology. As more scientific breakthroughs happen, the medical sector benefits from this, and as a result, the standard of living rises. Parking Alarm using Arduino Remember the situation, when you’ve parked the car or imagine you are parking a car. You need to look into the mirror and then you have to park the car. You may require another person to assist. Parking the car in a position is not a challenging task, but this project makes it better. This project helps to park the car in the parking area at a proper place easier. When the vehicle crosses the parking area, the buzzer makes the sound. This signal indicates the vehicle crossed the parking area. The sound of the buzzer continues until the vehicle is parked in the range of areas selected for parking. When the car is parked in the proper area, the buzzer will stop. Ultrasonic distance sensing technology is used for this process. Thus parking of the vehicle in the parking area is ensured by Ultrasonic Distance Sensing technology. Ultrasonic Distance Sensing technology is used in this project for parking assistance.
