Specification

Overview

Input and Output:

Input: Trigger signal sent by the microcontroller.
Output: Echo signal received by the microcontroller, used to calculate distance.

Physical Characteristics:

Dimensions: 45mm x 20mm x 15mm
Weight: Approx. 10g
Material: Plastic casing with electronic components

Technical Specifications:

Trigger Input Pulse: 10µs TTL pulse
Echo Output Pulse Width: Proportional to distance measured
Angle: 15-degree measuring angle

Additional Features:

Integrated temperature compensation for accurate readings.
Low power consumption ideal for battery-operated projects.

How to Use:

Connect the sensor to your microcontroller (e.g., Arduino) using the provided pins.
Send a 10µs pulse to the Trig pin to initiate measurement.
The Echo pin will go high, wait for the pulse to return, and measure the duration.
Use the duration to calculate the distance: Distance (cm) = (Time/2) / 29.1.
Display or use the distance value in your project as needed.

This sensor is perfect for distance measurement in robotics, obstacle detection, and various automation projects. It is straightforward to use with Arduino or other microcontrollers.
