Home Surveillance system using Ultrasonic Sensors.
In this paper, we are going to propose a system for the immediate cleaning of the dustbins. As dustbin is considered as a basic need to maintain the level of cleanliness in the city, so it is very important to clean all the dustbins as soon as they get filled. We will use ultrasonic sensors for this system.
By programming this sensor into a system along with a smart water valve kit, you can prevent excessive damage to your home due to flooding. Review this research paper on the development of a portable water level sensor for a flood management system. Ultrasonic Sensors in Motion Detection.
This project aims on the use of Ultrasonic Sensor by connected to the Arduino UNO R3 board and the signal from the sensor further provided to the screen formed on the laptop to measure the presence of any obstacle in front of the sensor as well as determine the range and angle at which the obstacle is detected by the sensor.
Figure 6: Measurement of high frequency and higher order vibration modes of an aluminium flexural ultrasonic transducer in air, at a distance of 0.5 metres with a burst-sine input of 10 V P-P and 150 cycles. This data was published in IEEE Sensors Journal in 2018. Note the difference in time scales for clarity.
In this research paper we propose an effective methodology for automatic control of braking system to avoid accidents. In this technology we used Ultrasonic sensor, LED, Buzzer, LCD and Micro controller is programmed with embedded C Language using PIC C Compiler.
Ultrasonic sensor actually consists of two parts: the emitter which produces a 40 kHz sound wave and detector which detects 40 kHz sound wave and sends electrical signal back to the microcontroller. HC-SR04 ultrasonic sensors are used which consist of 4 pins VCC, Trigger, Echo and GND. Features of Ultrasonic Sensor: Compact and light weight.
Ultrasonic Sensors measure the distance to the target by measuring the time between the emission and reception. An optical sensor has a transmitter and receiver, whereas an ultrasonic sensor uses a single ultrasonic element for both emission and reception.
