Product details
Technical specifications:
Working voltage: 3.3-5V DC
Static current:<2mA
Working current: 15mA
Measurement range: 2cm to 400cm
Resolution: 1 centimeter
Measurement angle: 15 degrees
Trigger input pulse width: 10 μ s
Echo pulse width: proportional to distance
Size: 45mm x 20mm x 15mm
Application:
Obstacle avoidance system
Distance measurement
object detection
Robot autonomous navigation
Liquid level measurement
Proximity sensing
Usage:
Contact:
Connect the VCC pin to a 5V power supply.
Ground the GND pin.
Connect the Trig pin to the digital output pin on the microcontroller.
Connect the Echo pin to the digital input pin on the microcontroller.
operation:
To initiate the measurement, please send a 10 µ s high pulse to the Trig pin.
The sensor will emit 8 cycles of ultrasonic bursts at a frequency of 40 kHz and set the Echo pin to high level.
Measure the duration of the Echo pin's high level to calculate the distance to the object (distance=duration * 0.034/2).
Programming:
Write a program on the microcontroller to send trigger pulses, read the duration of echo pulses, and calculate the distance.
Many microcontroller platforms, such as Arduino, have libraries that can be used to simplify the interface with HC-SR04.
