Ultrasonic Distance Sensor HCSR04 Module with Accuracy Measurement and Wide Detection Range

Ultrasonic Distance Sensor HCSR04 Module with Accuracy Measurement and Wide Detection Range Description

Key benefits Reliable distance sensing from 2 cm to 450 cm - covers both short and midrange detection needs. measurement precision with only 0.3 cm typical error, reducing false triggers and improving control decisions. Broad 3.3 V to 5 V compatibility, making the HCSR04 Sensor Module easy to integrate with a wide range of microcontrollers. Durable, compact design for straightforward installation and longterm performance in demanding environments. Main features Detection range: 2 cm - 450 cm for flexible application use. Accuracy: measurement error approximately 0.3 cm for precise readings. Voltage: operates across 3.3 V to 5 V supply voltages. Construction: built from durable materials and compactly designed to fit into constrained project spaces while resisting typical environmental stresses. How this module solves problems Minimizes accidental collisions and improves navigation by giving fast, accurate distance feedback for moving systems. Enables reliable level monitoring where contact sensors would foul or wear, as it measures distance without touching the medium. Simplifies automation tasks by providing consistent, repeatable measurements that can drive control logic for doors, gates, or safety interlocks. Practical use scenarios Robot obstacle avoidance: detect obstacles and trigger evasive maneuvers for mobile robots and autonomous platforms. Liquid level detection: noncontact level monitoring in tanks, reservoirs, and sump systems. Automatic door control: detect approaching users and reliably trigger opening/closing sequences for entrances and gateways. Why choose this HCSR04 Sensor Module Straightforward electrical compatibility and predictable accuracy reduce development time. Compact, robust design makes the module suitable for prototypes and finished products. Versatile performance across common voltage rails and usable in a variety of embedded and automation projects.
