Ping Sensor


i just connected the ping sensor with the radar scan,problem i hear a ,
knispering sound comming out the sensor.
is it broken ?


If it works it isn't broken.


i tested it works but what is that sound


here a video


Ultrasonic sensor uses sound. You're hearing the tick of the speaker that generates the ultrasonic sound


ah its normal then.


I could hear mine too when I'm close to it. I'm guessing the frequency is just below the ultrasonic range (or we have ultrasonic ears!).



thanks for telling
