Ultrasonic radar project report

For the mini-activities, student pairs use LEGO robot components to experiment with the sensors. Today we are investigating another sensor—the ultrasonic sensor. Have you heard of an ultrasonic sensor?

How to Make an Aircraft Invisible to Radar www. Before starting your experiment, read the instructions that come with your lux meter so that you know how to use it. Practice taking light measurements around your home from different sources. For example, see what kinds of light measurements you get from a lamp; a TV; beside a window, both with and without its blinds; and outside.

Constructing Your Test Box Cover all the inside surfaces of the box with black construction paper. Use tape to stick the construction paper to the inside of the box. Apply tape only to the back of the sheets of paper to avoid excessive visible tape inside the box, which could affect light scatter.

Use scissors to cut the paper to size, if necessary. It is okay to overlap sheets of paper. Tape the sensor part of the lux meter the part that receives light to the inside middle of one end of the box, as shown in Figure 4, below.

Position the sensor so that its base is resting on the bottom of the box and its back is taped to the end of the box, in the middle.

Let the display part of the lux meter hang outside one corner of the box. Using the tips of the scissors, cut a hole just above the sensor that is just big enough for the flashlight to fit through. Insert the flashlight about halfway through the hole so that the light source is inside the box and the on-off switch is outside the box.

With this arrangement, the sensor and the light source are nearly collocated. This photo shows how to set up your LED flashlight, lux meter sensor, and lux meter display on one end of the box.

Constructing Your Test Shapes Form a cylinder shape out of a piece of white paper by overlapping its short ends slightly and taping them together. The cylinder should be able to stand upright inside the box, without having the lid of the box touch it when the box is closed.

Crumple another piece of white paper into a loose ball, then un-crumple it, and repeat step 1. Fold a third piece of paper across its width into fourths, so that it has up-and-down ridges like a "W" when observed from the end.

When placed upright, the shape should be able to fit inside the box, without touching the lid when the box is closed. Fold a fourth piece of paper in half, across its width, so that it looks like a "V" when viewed from its end.

These drawings show the four test shapes. Finding a Good Location for Testing Inside the Box Place the regular cylinder in the center of the box, so that it is upright and directly in line with the flashlight. Using the pencil, make a mark on the bottom of the box that shows where the edge of the cylinder that is closest to the flashlight is located.

If the flaps on the lid of the box don't stay down, weigh them down lightly with your lab notebook. Turn on the lux meter.

Turn on the flashlight. Read the lux meter display to see how much light is being scattered back from the cylinder.1. Ultrasonic Range Finder using – This project as the name says, is an application to measure distance of an object.

It uses an ultrasonic transducer module HC-SR04 to measure the distance and the controller AT89S51 to make the necessary processing. In this engineering science fair project, students will determine which 3-D geometric shapes scatter light the most.

In the ultrasonic radar system developed by the authors, it is assumed that the human head is an object moving at a relatively high vertical position in a living area, and. An ultrasonic sensor transmit ultrasonic waves into the air and detects reflected waves from an object.

Ultrasonic transducer - Wikipedia

There are many applications for ultrasonic sensors, such as in intrusion alarm systems, automatic door openers and backup sensors for automobiles.

UltraSonic Radar - This is a very interesting project with many practical applications in security and alarm systems for homes, shops and cars.

it consists of a set of ultrasonic receiver and transmitter which operate at the same frequency. PIC18F microcontroller board radar robot project for detection msu05 ultrasonic sensor module this module is used instead of the alternative ultra sonic by adding other modules or op amp amplifier circuits, 40 kHz ultrasonic sensor can be used.
