Abstract: This paper describes a system, basically an electronic system that can help us to detect the exact location of the crack which has been formed accidently or due to the terrorist activities.

LabVIEW is a graphical programming language, used in many research fields for designing communication algorithms and simulating traditional as well as real time signals. Arduino kit can be interfaced ...

The SparkFun Ultrasonic Distance Sensor - TCT40 (sen-24805) a user-friendly upgrade to the popular HC-SR04 sensor, offers non-contact distance measurement from 2cm to 400cm with an accuracy of 3mm.

Works with the HC-SR04 ultrasonic sensor in the 3 Pin Mode/4 Pin Mode, the Ping))) ultrasonic sensor in the 3 Pin Mode and the DHT temperature/humidity sensors for getting precise distance values. !
