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 ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

To do this, he used an ultrasonic sensor similar to, but cheaper than a Parallax Ping unit. Paired with an Arduino, the sensor triggers the fog machine’s pump for 20 seconds whenever anyone gets ...

This project demonstrates an Automatic Water Level Controller using an Arduino Uno, HC-SR04 ultrasonic sensor, a relay module, and two push buttons. The ultrasonic sensor measures the distance from ...

The ultrasonic sensor uses sonar to determine the distance to an object. Here’s what happens: The ultrasound transmitter (trig pin) emits a high-frequency sound (40 kHz). The sound travels through the ...

How They Work The design of a robotic ultrasonic system is similar to collision avoidance and parking systems in cars. For example, ultrasonic sensors are embedded on the sides of a robotic vacuum to ...
