HC-SR04P 3-5V Ultrasonic Distance Sensor 2-400cm Range

Product Overview

The HC-SR04P is a high-performance, cost-effective ultrasonic distance sensor designed for non-contact range detection projects. Featuring a wide detection beam angle and excellent environmental adaptability, this sensor outperforms traditional IR sensors with broader obstacle detection coverage and more stable detection results.

With an effective measuring range of 2cm to 400cm and a high ranging accuracy of up to 3mm, the module delivers precise and consistent readings that are completely unaffected by sunlight exposure or target object colors. It integrates an ultrasonic transmitter, receiver, and control circuit in a compact size, requiring no external auxiliary circuits for normal operation.

Widely compatible with mainstream microcontroller platforms (especially Arduino), the sensor supports mature open-source libraries, enabling fast setup and simple programming for robotics obstacle avoidance, distance measurement, and intelligent device development projects.

Core Features

Ultra-Stable Detection: Readings are not interfered by sunlight, ambient light, or object surface colors, ensuring reliable outdoor and indoor use
High Precision & Wide Range: Supports 2cm-400cm non-contact measurement with 3mm high ranging accuracy and 1cm resolution
Wide Beam Angle Design: Provides larger detection coverage compared to ordinary infrared sensors, avoiding blind spots effectively
Plug & Play Setup: Built-in complete control circuit, no external circuit required, easy wiring and installation
Strong Compatibility: Fully compatible with Arduino and other mainstream microcontrollers, rich official & open-source libraries available
Compact & Economical: Mini size saves installation space, cost-effective for mass project development
