The Korea Research Institute of Standards and Science (KRISS) has developed an ultrasonic sensor technology that applies a waveguide to detect defects in all directions without directly attaching ...

As robots increasingly enter human spaces, robotics companies will need to think about safety differently than they did when robots were largely siloed from their human counterparts. Sonair thinks its ...

Sonair’s 3D ultrasonic sensor uses acoustic detection and ranging (ADAR) to enable 360° obstacle detection up to 5 meters. Each ADAR sensor offers a 180×180° field of view, allowing autonomous mobile ...

Social distancing among people is vital in minimizing spread of COVID-19 within community and can be effective in flattening the outbreak. This research work focuses on developing a close contact ...

Abstract: Internet of Things (IoT), Wireless Sensor Networks (WSN) and robotics systems consist of an embedded processor along with a myriad of possible sensors and actuators chosen according to the ...

Abstract: This research aims to develop a RADAR system using an ultrasonic sensor (HC-SR04), servo motor (SG90), and Arduino UNO. This RADAR system can detect objects in the vicinity and display ...

In the examples the HC-SR04 is used in one wire mode. The library supports one and two wires. Copy the content of the src/hcsr04 folder and place them in your project. The idea behind the library is ...

💧 Monitoring water tanker level using NodeMCU ESP8266 and HC-SR04P Ultrasonic Sensor and broadcasting it using a simple HTTP server inside NodeMCU ESP8266 and show data in an Android App ...
