15,00 EGPDescription
The HC-SR04 is an ultrasonic distance sensor module that measures the distance to an object using sound waves. It provides accurate and reliable distance measurements, making it ideal for robotics, obstacle avoidance systems, and other applications requiring distance sensing.
Key Features:
- Measurement Range: 2 cm to 400 cm (2m)
- Accuracy: Up to 3mm
- Operating Voltage: 5V (compatible with most microcontrollers like Arduino, Raspberry Pi, etc.)
- Operating Frequency: 40kHz (ultrasonic sound wave frequency)
- Signal Type: Digital Output (Echo and Trigger pins for distance measurement)
- Current Consumption: Low power consumption, typically around 15mA when idle and 20mA when active
- Mounting Type: Easy to mount on robots or other projects with simple pin connections
- Interface: 4-pin (VCC, GND, Trigger, Echo)
Pinout:
- VCC: Power supply pin (5V)
- GND: Ground pin
- Trigger (Trig): Sends a pulse to initiate the measurement (usually a 10us HIGH pulse)
- Echo: Outputs the time it takes for the ultrasonic sound wave to return (used to calculate distance)
Applications:
- Robotics: Used for obstacle detection and avoidance in autonomous robots.
- Distance Measurement: Ideal for measuring distances in projects requiring accurate and reliable distance readings.
- Parking Sensors: Used in automotive applications for proximity detection.
- Security Systems: Can be used for motion detection or proximity sensing in various security setups.
- Automation: Helps with automatic systems that require distance sensing or positioning, such as object detection and counting.
Benefits:
- Simple to Use: Easy to interface with most microcontrollers like Arduino, Raspberry Pi, and others.
- Affordable: Provides accurate distance measurements at an affordable price, making it perfect for hobbyists and DIY projects.
- High Accuracy: Offers precision with distances as close as 2cm and up to 400cm, making it suitable for a wide range of applications.
- Low Power Consumption: Efficient enough to be used in battery-powered projects, like mobile robots or drones.
The HC-SR04 Ultrasonic Distance Sensor Module is a reliable and cost-effective solution for distance measurement and obstacle detection, making it a popular choice for robotics, automation, and other electronic projects.
