A reliable and widely used ultrasonic sensor for measuring distance with good accuracy. Ideal for robotics, automation, and any project where you need non-contact distance measurement.

It works by sending out ultrasonic pulses and measuring the time it takes for the echo to return, giving you precise distance data that’s easy to process with a microcontroller.

Key Features

• Accurate distance measurement
• Simple trigger + echo interface
• Stable and consistent readings
• Easy integration with most microcontrollers
• 4-pin connection (VCC, GND, TRIG, ECHO)

Typical Uses

• Distance measurement
• Obstacle avoidance
• Smart robotics
• Level detection (liquids, objects)
