2 cm to 400 cm.
The HC-SR04 ultrasonic sensor uses SONAR to determine the distance of an object just like the bats do. It offers excellent non-contact range detection with high accuracy and stable readings in an easy-to-use package from 2 cm to 400 cm or 1 to 13 feet.
What is the maximum distance the ultrasonic sensor can detect?
They DO NOT measure farther than about 70 feet (21 meters). They DO NOT measure at very high repetition rates. Due to speed of sound limitations the fastest rate is 200 Hz at a max distance of about 24 inches.
What is the distance range of ultrasonic sensor?
Ultrasonic sensors are suitable for close range detection up to ten meters and provide multiple range measurements per second.
How do you increase the range of HC-SR04?
The HC-SR04 sensor provides 2cm to 400cm non-contact measurement function. You have at least one option to increase the measurement range of the sensors. The method that increases the range is using a parabolic dash to reduce the ‘field of view’ (FOV) of the basic sensor.
Why do ultrasonic sensors have a limited range?
There is more suppression of sound in a rising temperature and air humidity or a decreasing air pressure. As a result of this the detection range gets smaller, because the echo clearly has more difficulty to move through the air.
What is HC SR04 ultrasonic sensor?
The HC-SR04 Ultrasonic Distance Sensor is a sensor used for detecting the distance to an object using sonar.The HC-SR04 uses non-contact ultrasound sonar to measure the distance to an object, and consists of two ultrasonic transmitters (basically speakers), a receiver, and a control circuit.
What is the maximum range of an object does the ultrasonic sensor can detect in terms of centimeters?
Using the Ultrasonic Sensor
Generally, the ultrasonic sensor is used for distances of 10 centimeters or more, whereas the light sensor is used at shorter distances.
How does a HC-SR04 work?
At its core, the HC-SR04 Ultrasonic distance sensor consists of two ultrasonic transducers. The one acts as a transmitter which converts electrical signal into 40 KHz ultrasonic sound pulses. The receiver listens for the transmitted pulses.
Is HC-SR04 waterproof?
However, using the HC-SR04 outside is a different story. It is a pretty fragile device and can easily be damaged by dirt, or even high winds. And, above all, it is not waterproof.
How do I connect 4 pin ultrasonic sensor to Arduino?
This is a very simple and useful ultrasonic sensor. There are four pins that you would use to interface with the sensor: VCC, Trig (signal output pin), Echo (signal input pin), and GND. Each of the four pins are connected to the Arduino: VCC to 5v, Trig to a digital pin, Echo to a digital pin, and GND to GND (ground).
Which sensor has highest detection range?
Ultrasonic Sensor
The Ultrasonic Sensor is arguably the most common distance measuring sensor, also known as the Sonar sensor. It detects the distance to objects by emitting high-frequency sound waves.
How is ultrasonic sensor distance calculated?
To measure the distance the sound has travelled we use the formula: Distance = (Time x SpeedOfSound) / 2. The “2” is in the formula because the sound has to travel back and forth. First the sound travels away from the sensor, and then it bounces off of a surface and returns back.
What is the range of HC-SR04 ultrasonic sensor detection?
2 cm to 400 cm
The HC-SR04 ultrasonic sensor uses SONAR to determine the distance of an object just like the bats do. It offers excellent non-contact range detection with high accuracy and stable readings in an easy-to-use package from 2 cm to 400 cm or 1 to 13 feet.
What are the 4 pins of the HC-SR04?
The HC-SR04 Ultrasonic sensor comes with four pins namely Vcc pin, Trigger pin, Echo pin, & Ground pin. This sensor is used to measure the accurate distance between the target and the sensor. This sensor mostly works on the sound waves.

Which sensor is used to detect water level?
Hydrostatic pressure level sensors are submersible sensors used for measuring the level of liquids (including corrosive liquids) in deep tanks or water in reservoirs.
Can ultrasonic sensor detect water level?
With ultrasonic sensors, we can find the water depth calculation by finding the distance between the transceiver and the surface of the water. The sensor will transmit a short ultrasonic pulse, and we can measure the travel time of that pulse (the echo) to the liquid and back.
Can ultrasonic sensor detect human?
Human Presence Detection with Ultrasonic Sensors. MaxBotix ultrasonic sensors solve the common problem of sensing human presence. Our ultrasonic sensors offer the ability to detect people over a wide range of distances with a high read rate and excellent reading to reading stability.
How does Arduino measure distance?
Two sensors for measuring distance with the Arduino are extremely popular: the infrared proximity sensor and the ultrasonic range finder. They work in similar ways and achieve pretty much the same thing, but it’s important to pick the right sensor for the environment you’re in.
What are range sensors?
Range sensors are devices that capture the three-dimensional (3-D) structure of the world from the viewpoint of the sensor, usually measuring the depth to the nearest surfaces. These measurements could be at a single point, across a scanning plane, or a full image with depth measurements at every point.
Which metal will have a larger range of detection by inductive proximity sensor?
Explanation: Steel will have a larger range of detection by inductive proximity sensor. A ferrous metal enables a longer range of detection where as non-ferrous metals can reduce the sensing range by 60%.
