• Ultrasonic Transmitters

Ultrasonic receivers are used for detecting sound waves that have a frequency greater than 20,000 Hz. The ultrasonic receiver MB7489-110 utilizes an acoustic MEMS (Microelectromechanical System) which has small electrical transducers that convert the received sound wave into an electrical signal. The receiver is focused on receiving acoustic signals and does not detect radio signals.

MB7489-110 can receive sound waves in applications such as measuring distances, obstacle detection, industrial automation, and security. As an example, it can be used for an ultrasonic proximity detector, where the receiver can be placed in a certain area and detect how close an object is to it. For security applications, MB7489-110 can detect changes in sound levels and vibrations in its receivers range, therefore helping identify potential threats.

The working principle of MB7489-110 involves two main parts: the acoustic diaphragm and the amplifier. first, sound waves generated by a nearby source vibrate the diaphragm and cause the acoustic pressure to change. The vibrations of the diaphragm then generate a voltage output which is converted in electrical signal by the amplifier. The amplifier then processes the electrical signal and identifies the sound waves that were sent by the source.

MB7489-110 has a low-frequency resolution, which means it can accurately detect sound waves with a frequency of around 10 - 20 kHz. This frequency range is typical for applications such as burglar alarms, industrial automation, and proximity detectors. It also has a wide working temperature range, which makes it ideal for various environmental conditions. The receiver also requires low power consumption, so it can be used in wireless applications without draining too much energy.

Overall, MB7489-110 is a reliable ultrasonic receiver used for several applications. Its low-frequency resolution and wide working temperature range make it suitable for most applications. Additionally, it has low-power requirements which makes it suitable for wireless use. This receiver is a great choice for those who want an effective solution for detecting sound waves and distances without having to spend a lot of money.
