Ultrasonic receivers, transmitters and MB7363-801 are key components in the field of ultrasonic communication. As a kind of ultrasonic receiver transmitter, MB7363-801 takes a great share in the industry.

Widely applied in distance ranging, speed measurement and flowmeter based on the detection of the reflected energy from the corresponding target, MB7363-801 plays an especially important role in the areas related to automotive safety such as parking assistance. Also, it possesses the combinations of advanced features, and can be used for industrial and commercial applications like object size measurements, proximity sensors and beam and door openers.

MB7363-801 consists of several parts. First, it is built with transducer. Its task is to convert received ultrasonic sound signal into electrical signal, and send out the ultrasonic wave when powered. Second, it is built with a receiver which is responsible for picking up the signal and amplification. Third, it consists of a logic circuit, which is composed of integrated circuits with logic control functions, and leads the receiver, trigger signal, transmitting and receiving time, as well as other parts of MB7363-801 to work together.

The working principle of MB7363-801 mainly includes three parts: transmitting, receiving and processing. First, when power applied, transducer in MB7363-801 will start transmitting ultrasonic wave to a certain direction. Then after the ultrasonic wave being reflected by the specific target, the transducer of the MB7363-801 will receive the reflected signal. Following that, the received signal will be forwarded to the receiver, and the amplified signal is further processed by the logic circuit.

After the signal being processed, it could be outputted to two different pins. An “echo” signal will be output from the “echo” pin in order to inform there is an echo getting back, and the pulse width (or the time difference between transmitting and receiving process) of the signal will be also outputted to the “OUT” pin.

By making use of the time difference between sending and receiving signals, MB7363-801 could be used to estimating the distance between the transmitter and the certain target. This ultrasonic receiver transmitter could also be used to measurement the size of the object by calculating the addition and subtraction the time between sending and receiving of signals.

In conclusion, MB7363-801 is an important part of the ultrasonic communication field. It has vast application, such as automotive parking assistance, industrial and commercial applications, distance ranging, speed measurement and object size measurement. Its working principle is that it sends and receives the ultrasonic signal and process this signal with its logic circuit to estimate the distance between itself and the corresponding target.
