Hc Sr04 Ultrasonic Sensor Range

The basic principle of work.
Hc sr04 ultrasonic sensor range. It offers excellent non contact range detection with high accuracy and stable readings in an easy to use package. The hc sr04 ultrasonic sensor uses sonar to determine the distance to an object like bats do. The hc sr04 ultrasonic sensor uses sonar to determine distance to an object like bats do. This sensor is a very popular sensor used in many applications where measuring distance or sensing objects are required.
Trig trigger pin is used to trigger the ultrasonic sound pulses. Ultrasonic ranging module hc sr04 provides 2cm 400cm non contact measurement function the ranging accuracy can reach to 3mm. Vcc is the power supply for hc sr04 ultrasonic distance sensor which we connect the 5v pin on the arduino. Ultrasonic sensor hc sr04 the ultrasonic sensor hc sr04 uses sonar to determine distance to an object.
It offers excellent non contact range detection with high accuracy and stable readings in an easy to use package. Hc sr04 ultrasonic sensor working. The hc sr04 ultrasonic range finder is very simple to use however the signal it outputs needs to be converted from 5v to 3 3v so as not to damage in previous tutorials we ve outlined temperature sensing pir motion controllers and buttons and switches all of which can plug directly into the raspberry pi s gpio ports. Sainsmart ultrasonic ranging detector mod hc sr04 distance sensor blue providing 2cm to 400cm of non contact measurement stable performance accurate measurement range.
The length of the pulse is proportional to the time it took for the transmitted signal to be detected. It offers excellent non contact range detection with high accuracy and stable readings in an easy to use package. The hc sr04 ultrasonic us sensor is an ultrasonic transducer that comes with 4 pin interface named as vcc trigger echo and ground. Ultrasonic ranging module hc sr04 product features.
Using io trigger for at least 10us high level signal. As shown above the hc sr04 ultrasonic us sensor is a 4 pin module whose pin names are vcc trigger echo and ground respectively. From 2cm to 400 cm or 1 to 13 feet. The modules includes ultrasonic transmitters receiver and control circuit.
