The Datasheet Hc Sr04 is your guide to understanding and utilizing the popular HC-SR04 ultrasonic distance sensor. This small, affordable sensor is a favorite among hobbyists, students, and professionals for its ability to measure distances without physical contact. Mastering the information within the Datasheet Hc Sr04 is crucial for successful integration into any project that requires distance detection.
Understanding the Datasheet Hc Sr04 and Its Applications
The Datasheet Hc Sr04, in essence, provides all the technical specifications and operating instructions for the HC-SR04 ultrasonic sensor. It details everything from the sensor’s power requirements and pin configurations to its measurement range and accuracy. Understanding this datasheet is vital because it allows you to properly connect, configure, and interpret the data provided by the sensor, ensuring optimal performance and preventing potential damage to your circuit. It’s essentially the blueprint for making the sensor work correctly in your specific application.
These sensors work by emitting a short burst of ultrasonic sound waves and then listening for the echo when the sound bounces off an object. The sensor calculates the distance to the object based on the time it takes for the echo to return. The datasheet will give you the specific frequency of the sound wave, the recommended timing for sending and receiving the signals, and the formulas for converting the time of flight into distance. Without this information, obtaining accurate and reliable distance measurements would be a guessing game. For example, the datasheet will specify important parameters like:
- Operating Voltage: Typically 5V DC
- Measuring Angle: The effective angle of the sensor’s cone
- Measuring Distance: Minimum and Maximum range
The applications of the HC-SR04 are incredibly diverse, ranging from simple obstacle avoidance in robots to more complex uses in liquid level sensing and parking assistance systems. The datasheet helps you understand the limitations of the sensor, such as its sensitivity to temperature and humidity, and how to compensate for these factors in your designs. Consider the following table for example, highlighting the key performance metrics.
| Parameter | Typical Value |
|---|---|
| Operating Frequency | 40 kHz |
| Measuring Range | 2cm - 400cm |
| Accuracy | 3mm |
