Ultrasonic Sensor HC-SR04 and Arduino – Complete Guide

WebHC-SR04 Hardware Overview. The HC-SR04 is an affordable and easy to use distance measuring sensor which has a range from 2cm to 400cm (about an inch to 13 feet). The sensor is composed of two ultrasonic transducers. One is transmitter which outputs ultrasonic sound pulses and the other is receiver which listens for reflected waves. Web18 dec. 2024 · For a project I need to use many distance sensors HC-SR04 using less pins possible of a Pi Zero W. I was able to do a test program in python3 with one sensor connected using gpiozero library and it worked. Then, I wanted to use a multiplexer 5v with two sensors. I used a Toshiba TC74HC4051AP. This is the connection that I have used:

Did you know?

WebAnalog output processing lets a fixed HC-SR04 sensor detect multiple objects. HC-SR04 ultrasonic sensors are useful in a wide variety of automation tasks, for determining the distance to an object. If you need to deal with multiple objects, this normally means buying or building a scanning setup, or perhaps mounting a few fixed sensors at ... Web13 sept. 2014 · Each sensor has its trigger pin, you should send the signal at the trigger pin and read the echo pin form the same sensor, and then repeat for the other sensor. You must perform a reading time, at least 60 ms between readings according to datasheet (HC-SR04 Datasheet). Use the interrupt makes the timing most accurate measure.

Web23 mar. 2024 · However, after a time-out and with the distance between the object and the sensor in range, the Echo pin fails to be set low after a trigger pulse is generated. The only way to fix this condition is to power down the sensor and power it back up again. (I have verified the state of the Echo pin by using an oscilloscope.) hc-sr04. Share. Web3 feb. 2016 · 1 Answer. Change the serial print to display 'Duration', to see if the problem lies in the centimetre conversion.
