5Pin HY-SRF05 Ultrasonic Distance Sensor Module
The HY-SRF05 Ultrasonic Distance Sensor Module is a high-precision ultrasonic ranging sensor designed for measuring distances from 2cm to 450cm. Operating at 5V DC, it uses ultrasonic waves to detect objects and calculate distance with an accuracy of up to 0.3cm. The module features separate Trigger and Echo pins for easy interfacing with microcontrollers such as Arduino, ESP32, and Raspberry Pi. With its compact design, low power consumption, and reliable performance, the HY-SRF05 is ideal for robotics, obstacle avoidance, automation systems, distance measurement, and smart sensing applications.
يُعد HY-SRF05 مستشعر مسافة بالموجات فوق الصوتية عالي الدقة، مصممًا لقياس المسافات ضمن نطاق يتراوح بين 2 سم و450 سم. يعمل بجهد 5 فولت DC ويستخدم الموجات فوق الصوتية لاكتشاف الأجسام وحساب المسافة بدقة تصل إلى 0.3 سم. يحتوي على أطراف منفصلة للإرسال والاستقبال (Trigger و Echo) مما يسهل توصيله مع المتحكمات الدقيقة مثل Arduino وESP32 وRaspberry Pi. بفضل حجمه الصغير واستهلاكه المنخفض للطاقة وأدائه الموثوق، يُستخدم على نطاق واسع في الروبوتات وأنظمة تجنب العوائق والأتمتة وقياس المسافات الذكي.
The HY-SRF05 Ultrasonic Distance Sensor Module is a versatile and accurate distance measurement device that utilizes ultrasonic sound waves to determine the distance between the sensor and an object. The module emits a burst of ultrasonic waves at 40kHz and measures the time taken for the echo to return after reflecting from a target object.
Designed for easy integration with microcontrollers and development platforms, the HY-SRF05 features dedicated Trigger (Trig) and Echo pins for precise timing measurements. It is fully compatible with Arduino libraries and electronic brick interfaces, making it an excellent choice for beginners and advanced developers alike.
The sensor can measure distances from as close as 2cm up to 450cm, with a narrow detection angle of approximately 15 degrees for focused sensing. Its high accuracy and low power consumption make it suitable for robotics, automation, smart devices, security systems, and industrial monitoring applications.
The module includes a dual-transducer design for transmitting and receiving ultrasonic signals, ensuring stable and reliable performance in a wide range of environmental conditions.
