HCSR04 Ultrasonic Sensor Module — durable, compact distance sensing for reliable measurements Key benefits Accurate distance measurement: HCSR04 ultrasonic sensor provides a wide detection range from 2cm to 450cm for reliable short- and mid-range readings. Durable and compact design: Built with durable materials and a compact form factor so it fits into tight spaces and withstands everyday project use. Easy integration: Compact layout and standard signal behavior make the module simple to incorporate into electronic projects and prototypes. Reliable in varied conditions: Engineered to provide robust performance even under challenging environmental conditions. How it solves problems Replaces imprecise or contact-based methods with non-contact ultrasonic measurement for safer, cleaner sensing. Delivers consistent readings across a wide range, reducing the need for repeated calibration in many applications. Compact, durable construction minimizes enclosure redesigns and speeds up development and deployment.
