HC-SR04 Ultrasonic Sensor Module
This ultrasonic sensor module can be used for measuring distance, object sensor, motion sensors etc. High sensitive module can be used with a microcontroller to integrate with motion circuits to make robotic projects and other distance, position & motion sensitive products.
The module sends eight 40 KHz square wave pulses and automatically detects whether it receives the returning signal. If there is a signal returning, a high-level pulse is sent on the echo pin. The length of this pulse is the time it took the signal from first triggering to the return echo.
Ultrasonic Distance Sensor provides very short (2CM) to long-range (4M) detection and ranging. The sensor provides precise and stable non-contact distance measurements from about 2cm to 4 meters with very high accuracy. It can be easily interfaced to any microcontroller.
Key Features:
- High Accuracy: Provides accurate distance measurements with a range of 2cm to 400cm, making it ideal for precise object detection.
- Easy Integration: Simple to connect with microcontrollers, Arduino, Raspberry Pi, and other development platforms using standard pins.
- Wide Range of Applications: Suitable for robotics, obstacle avoidance systems, distance measurement, and level sensing.
- Compact Design: Lightweight and compact, this module can be easily incorporated into various projects without taking up much space.
- Low Power Consumption: Designed for low power consumption, making it suitable for battery-operated devices.
Technical Specifications:
- Sensor Type: Ultrasonic
- Output: Digital Sensor
- Voltage: 5VDC
- Detection distance: 2cm-400cm (0.02M – 4.0M)
- Static current: < 2mA
- Level output: high-5V
- High precision: up to 0.3cm
Package Includes:
- 1 Piece-HC-SR04 Ultrasonic Sensor Module
