Frequently Bought Together

This ultrasonic sensor module is used for measuring distance, object sensor, motion sensors etc. HC-SR04 Can connect with microcontroller to integrate with motion circuits to make robotic projects and other distance, position & motion sensitive products.

HC-SR04 sends eight 40Khz 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.

Electrical Characteristics:
    • Operating voltage: +5V
    • Theoretical  Measuring Distance: 2cm to 450cm
    • Practical Measuring Distance: 2cm to 80cm
    • Accuracy: 3mm
    • Measuring angle covered: <15°
    • Operating Current: <15mA
    • Operating Frequency: 40Hz
Connections:
    • Vcc – The Vcc pin powers the sensor, typically with +5V
    • Trigger – Trigger pin is an Input pin. This pin has to be kept high for 10us to initialize measurement by sending US wave.
    • Echo – Echo pin is an Output pin. This pin goes high for a period of time which will be equal to the time taken for the US wave to return back to the sensor.
    • Ground – This pin is connected to the Ground of the system.
Applications:
    • Used to avoid and detect obstacles with robots like biped robot, obstacle avoider robot, path finding robot etc.
    • Used to measure the distance within a wide range of 2cm to 400cm
    • Can be used to map the objects surrounding the sensor by rotating it
    • Depth of certain places like wells, pits etc can be measured since the waves can penetrate through water
Package Includes:
    • HC-SR04 HCSR04 Ultrasonic Wave Detector Range Finder Sensor Module Distance Measuring Transducer for Arduino
