The SRF05 Ultrasonic Distance Sensor is a versatile and popular sensor module used for measuring distances between objects without physical contact. It employs ultrasonic sound waves to determine the distance to a target object and is commonly used in robotics, automation, and various electronic projects. The SRF05 sensor is equipped with an ultrasonic transceiver, which emits ultrasonic pulses and measures the time it takes for the pulses to bounce back after hitting an object. This time measurement is then used to calculate the distance accurately.

Specificatoins of HY-SRF05 Ultrasonic Distance Sensor Module:

  • Operating Principle: Ultrasonic distance measurement using sound waves.
  • Measurement Range: Typically ranges from 2 centimeters to 450 centimeters (2cm - 450cm), adjustable based on the application.
  • Ultrasonic Frequency: Typically operates at 40 kHz.
  • Accuracy: High accuracy with a resolution of 0.3 centimeters.
  • Interface: Connects to microcontrollers or development boards via digital I/O pins (typically Trigger and Echo).
  • Operating Voltage: 5V DC.
  • Trigger Pulse: Generates a short trigger pulse to initiate distance measurement.
  • Echo Signal: Receives the reflected ultrasonic pulse and provides an output signal.
  • Control Pins: Often includes pins for controlling the module, such as mode selection or power.
  • Operating Temperature: -20°C to +70°C.
  • Dimensions: 45mm x 20mm x 15mm

Features of HY-SRF05 Ultrasonic Distance Sensor Module:

  • Accurate Distance Measurement: Provides highly accurate distance measurements with a high resolution.
  • Wide Measurement Range: Offers a versatile range from 2cm to 450cm, adjustable as needed.
  • Easy Integration: Interfaces easily with microcontrollers and development boards using digital pins.
  • Low Power Consumption: Consumes relatively low power during operation.
  • Compact Design: Compact and lightweight for easy integration into projects.
  • Usage Tip:
  • Ensure that the trigger and echo pins of the sensor are connected correctly to your microcontroller or development board.
  • Account for the speed of sound in your environment (approximately 343 meters per second at 20°C) when interpreting the time-of-flight measurement to calculate distance.
  • Caution:
  • Handle the sensor with care to avoid damage to the transceiver element.
  • Avoid exposing the sensor to extreme temperature or humidity conditions outside its specified operating range.
