Key Features: Operating Voltage: 4.5V to 5.5V DC Detection Range: 2 cm to 450 cm (0.8" to 14.7 ft) Accuracy: ±3 mm GPIO Interface: 4-pin header (VCC, TRIG, ECHO, GND) Operating Frequency: 40 kHz Low Standby Current: <2 mA Detection Angle: ≤15 degrees Compact Design: 45 mm x 20 mm x 15 mm Dual Mode Support: Can be used in either single-pin or dual-pin trigger/echo mode for compatibility with a wide range of controllers Example Installation Scenario: For autonomous robotics, the HY-SRF05 sensor can be mounted on a mobile robot platform to continuously scan for objects in its path. By measuring the time interval between ultrasonic pulse emission and echo reception, the robot determines the proximity of obstacles and adjusts its path accordingly. Whether navigating tight indoor corridors or avoiding collisions in dynamic environments, this sensor enables responsive, real-time decision-making.
