i connected the ultrasonic sensor to the 3.3 vcc and ground and the trig and echo pins to GPIO22,1 when i connect the sensor i get MD5 error:"A fatal error occurred: MD5 of file does not match data in flash!" any help will be greatly appriciated...
An ultrasonic sensor generates high-frequency sound (ultrasound) waves. When this ultrasound hits the object, it reflects as echo which is sensed by the receiver as shown in below figure. Ultrasonic Sensor Working Principle By measuring the time required for the echo to reach to the receiver, w...

It allowed achieving the frequency bandwidth (14–18)% with respect to the central frequency at −3 dB level. Keywords: air-coupled ultrasonic transducers; PMN-32%PT crystals; ultrasonic array 1. Introduction Air-coupled ultrasonics is a non-contact technique which is already used in non-...
Then, a multi-ray modeling process has been provided based on the beam pattern of the MaxSonar MB1222 ultrasonic sensor. The comparative test validates that the proposed model has good fitness with the actual sensor for indoor localization. Based on the multi-ray model, an EKF-based indoor ...
