Interfacing Ultrasonic Sensor HC-SR04 with PIC Microcontroller Raspberry Pi Based Obstacle Avoiding Robot using Ultrasonic Sensor IoT Based Dumpster Monitoring using Arduino & ESP8266 HC-SR04 ...

The dispenser uses ultrasonic sensor HC-SR04 to detect hands when these are put beneath the container. It dispenses the required amount of sanitiser automatically for specific time and then gets ready ...

Arduino UNO circuit board [8] and an HC-SR04 ultrasonic distance sensor [9] were used for data collection and are shown in Figure 2. Arduino UNO was placed on upper face of top plate and ultrasonic ...

Default value for maximum measurement distance is 4m, since HC-SR04 sensor can't measure reliably beyond that. However, if you are using another sensor or if you you don't care about distances larger ...

The JSN-SR04T Waterproof Ultrasonic Sensor As well as the familiar ultrasonic ranging module HC-SR04, another one seen on online markets is the JSN-SR04 (and variants). The JSN-SR04 ultrasonic ranging ...

Ultrasonic sensor, also known as a SONAR sensor is an electronic device that is used to measure the distance of a target object by emitting ultrasonic sound waves. Apart from distance measurement, it ...

HC-SR 04 Ultrasonic sensor is most commonly used to measure distance, but this time I will show you how to measure the speed of movement of an object using ...
