Ultrasonic Sensors FAQ

Characteristics 
Waterproof type/Open-Structure type/High-Frequency type

Is it possible to make the sensor directive by an electrical means?

It is difficult to electrically control the beam pattern of Murata ultrasonic sensors. (With a sensor having broad resonance characteristics, it is possible to more or less control the beam pattern by changing the frequency of the drive signal. The drawback is that the broad resonance characteristics result in lower sound pressure.)
