Testing and Monitoring Ultrasonic Sensors for Engineering Education on Electronic Measurements

Accurate training on electronic measurements can be obtained while experimenting with real sensors, electronic circuits and equipments. The paper presents an experimental system that allows the study and testing for two ultrasonic sensors, the remote programming for one of them and the monitoring of switching output for each sensor. A programmable logic controller performs the sensor remote programming and monitoring. The guideline for studying, testing and monitoring the ultrasonic sensors helps students to select, comprehend and apply information from datasheets and catalogs, use the previously acquired theoretical knowledge, understand the sensor connection to the programmable logic controller for implementing the sensor remote programming and monitoring. The engineering undergraduates acquire new practical skills using ultrasonic sensors and programmable logic controller, analogue and digital circuits and other devices. The experimental system presented in this paper has been proved very useful in academic study for experimental training on electronic measurements.
