Whadda UK Ultrasonic Distance Sensor for Arduino

The Whadda UK Ultrasonic Distance Sensor is an essential component for robotics, automation, and Arduino-based projects requiring precise non-contact distance measurement. This compact sensor emits ultrasonic waves at a 40kHz frequency to accurately detect objects and obstacles, making it ideal for building autonomous buggies, robots, and interactive installations where collision avoidance is critical.

It features a robust detection range from 30mm to an impressive 5.5 metres, with a high resolution of 0.3cm. The sensor operates on a low voltage DC supply from 3.3V to 5.5V, ensuring compatibility with most microcontrollers like the Arduino Uno, Nano, and Mega. Its 15-degree measurement angle provides a focused detection field, reducing false readings from peripheral objects.

Connection is straightforward via its standard 5-pin interface (GND, OUT, TRIG, Echo, VCC), and it is triggered by a simple 10µS pulse. The compact dimensions allow for easy integration into tight spaces within your project chassis.

• Ideal for Robotics: Perfect for obstacle detection and avoidance in moving vehicles.
• Accurate Ranging: Provides reliable distance data for navigation and positioning.
• Easy Integration: Simple 5-pin interface compatible with common development boards.
• Wide Operating Voltage: Works seamlessly with 3.3V and 5V logic systems.

This sensor is a key tool for educators, hobbyists, and engineers developing smart, responsive electronic projects.
