[Emil] got his hands on a dozen HC-SR04 ultrasonic sensors, but wasn’t too happy with their performance. Rather than give up, he reverse engineered the sensor and built an improved version. Hackers, ...
Infrared certainly has its uses, but if you’re trying to locate objects, ultrasonic detection is far superior. It’s contact-less, undetectable to the human ear, and it isn’t affected by smoke, dust, ...
Simple Publisher-Subscriber to measure distance from an ultrasonic sensor. Hardware consisting on an RPi connected to an Arduino running ROS Arduino Bridge ...
Makers, developers and enthusiasts building distance related projects may be interested to know that the HC-SR04 ultrasonic sonar distance sensor is now available to purchase directly from the ...
HY-SRF05 work based on Principle of Ultrasonic Echo-Ranging. This module has 2 sensors, one to trigger an ultrasonic waves, and one to receive ultrasonic waves. Trigger Sensor, send a short pulse to ...
The main goal of this application is to design an ultrasonic qualitative distance estimation sensor using Dialog Semiconductor’s SLG47105V. The system is designed using high-voltage (HV) macrocells ...
Abstract: The idea of using mobile robots to different applications is very common today. For choosing the best hardware and software configuration for the mobile robot it is necessary in order to ...
Abstract: This paper presents two PZT piezoelectric micromachined ultrasonic transducer (PMUT) designs for distance sensing applications, fabricated using a foundry-compatible multi-project wafer (MPW ...
