Senzor Ultrasonic Hc Sr04

About this project in this project i will introduce you to the hc sr04 ultrasonic sensor.

Senzor ultrasonic hc sr04. It is compatible with arduino and it has some advantages over the analog distance sensors. You can determine how far away something is by the time it takes for the sound waves to get back to the sensor. Hc sr04 hardware overview at its core the hc sr04 ultrasonic distance sensor consists of two ultrasonic transducers. Hai sir as we know ultrasonic sensor range is aout 2cm to 400cm.

The modules includes ultrasonic transmitters receiver and control circuit. The one acts as a transmitter which converts electrical signal into 40 khz ultrasonic sound pulses. These ubiquitous sensors are really common in robotics projects but they can also be used for automation interactive art and motion sensing. It comes complete with ultrasonic transmitter and receiver modules.

It is commonly used in obstacle avoiding robots and automation projects. This sensor is a very popular sensor used in many applications where measuring distance or sensing objects are required. In this tutorial you will learn how the sensor works and how to use it with arduino. The hc sr04 ultrasonic sensor is one of the most popular and easy to use distance sensors.

It works by sending sound waves from the transmitter which then bounce off of an object and then return to the receiver. în special folosit pentru proiectele cu plăci de dezvoltare arduino are avantaje față de senzorii analogici necesitând doar pini i o digitali și are imunitate mai mare la zgomotul din jur. Until genetic modifications catches up with our desires we ll just have to make do with these handy hc sr04 ultrasonic sonar distance sensors and a pair of flippers. Ultrasonic ranging module hc sr04 provides 2cm 400cm non contact measurement function the ranging accuracy can reach to 3mm.

The receiver listens for the transmitted pulses. It needs only digital i o pins it has higher noise immunity and better precision. Hc sr04 ultrasonic sensor working as shown above the hc sr04 ultrasonic us sensor is a 4 pin module whose pin names are vcc trigger echo and ground respectively. The hc sr04 ultrasonic sensor uses sonar to determine distance to an object like bats do.

Senzor ultrasonic hc sr04 senzorul ultrasonic hc sr04 este unul dintre cei mai utilizați senzori pentru aflarea distanței. The hc sr04 is an inexpensive easy to use ultrasonic distance sensor with a range of 2 to 400 cm. It offers excellent non contact range detection with high accuracy and stable readings in an easy to use package.
