Description: The devices used to transmit and receive the ultrasonic sound waves in this application are
40-kHz ceramic ultrasonic transducers. The MSP430 drives the transmitter transducer with a
12-cycle burst of 40-kHz square-wave signal derived from the crystal oscillator, and the receiver
transducer receives the echo.

Description: The report details the implementation of distance measurement system using the
ultrasonic waves. As the human ear’s audible perception range is 20 Hz to 20 kHz, it is
insensitive to ultrasonic waves, and hence the ultrasound waves can be used for applications in
industries/vehicles without hindering human activity. They are widely used as range meters and
proximity detectors in industries also it can be used in parking assistance system. The distance
can be measured using pulse echo and phase measurement method. Here the pulse echo method
is used. The measurement unit uses a continuous signal in the transmission frequency range of
ultrasonic transducers. The signal is transmitted by an ultrasonic transducer, reflected by an
obstacle and received by another transducer where the signal is detected. The time delay of the
transmitted and the received signal corresponds to the distance between the system and the
obstacle.

sound of up to 20kHz frequency
only. This proximity
detector works at a frequency of 40
kHz. It uses two specially made ultrasonic
transducers: One transducer
emits 40kHz sound, while the other
receives 40kHz sound and converts it
into electrical variation of the same frequency.

Description: This paper presents the generic model of intelligent
instruments and specifies it for intelligent sensors, from a functional
point of view, i.e., from the point of view of the services they
offer to the system designer. Basic services are concerned with data
estimation and data characterization, both based on local transducers
and on the availability of remote signals. Advanced services
are concerned with data validation, through fault detection and isolation procedures, and with fault tolerance, by means of accommodation
and reconfiguration strategies. Finally, the integration of intelligent sensors in distributed control systems is discussed.
