The modules includes ultrasonic transmitters, receiver and control circuit. The basic principle of work: (1) Using IO trigger for at least 10us high level signal,. The ranging accuracy can reach to 3mm and effectual.
This datasheet is provided by: e-radionica. The human ear can hear sound frequency around 20HZ ~ 20KHZ, and .
TTL level signal, proportional to.
The purpose of this file is to explain how the HCSRworks.
This section contains the specifications and why they are important to the sensor module. It comes complete with ultrasonic transmitter and receiver module. The HCSRultrasonic sensor uses sonar to determine distance to an object like bats or. But it has the same ranging accuracy and longer ranging distance. Considering the travel time and the speed of the sound you can calculate the distance.
We power the module using Vcc, ground it using GN and use our Raspberry Pi to send an input signal to TRIG, . Finally , look at the back of the module. All of the chip in the module have been burnish , maybe the author want to prevent the designed from plagiarism. This prevents any echos from the previous ultrasonic pulse interfering with the next pulse measurement or the new outgoing pulse being heard as the echo from the previous pulse.
HC - SRhas stable performance and high ranging accuracy. Working Voltage : 5V(DC) , Static current: Less than 2mA. Output signal : Electric frequency signal, high level 5V, low level 0V. Detection distance : 2cm-450cm. Sensor angle : Not more than degrees.
Low cost ultrasonic technology based distance measurement, obstacle sensing module with easy and simple interface with microcontrollers. Good for robotics or other automation products. Its stable performance and high ranging . It is able to measure distances from 2cm to 400cm with an accuracy of about 3mm.
This module includes ultrasonic transmitter, ultrasonic receiver and its control circuit.
