HC-SR04-Ultrasonic Range Finder

Description

The HC-SR04-Ultrasonic Range Finder is a high-grade, precision-tested electronic component designed for reliable performance in prototyping, education, industrial control, and custom hardware engineering.

🔹 Key Features

• •The module has two eyes like projects in the front which forms the Ultrasonic transmitter and Receiver
• •The HC-SR04 ultrasonic sensor uses sonar to determine the distance to an object like bats or dolphins do
• •This Ultrasonic Sensor module is a transmitter, a receiver, and a control circuit in one single pack!! It has very handy and compact construction
• •It offers excellent range accuracy and stable readings in an easy-to-use package
• •The Trigger and the Echo pins are the I/O pins of this module and hence they can be connected to the I/O pins of the microcontroller/Arduino
• •Ultrasonic Ranging Module HC-SR04 provides 2cm-400cm non-contact distance sensing capabilities, Ranging accuracy up to 3mm
