HC-SR04 Ultrasonic Range Sensor on the Raspberry Pi | The ...

· The HC-SR04 sensor requires a short 10uS pulse to trigger the module, which will cause the sensor to start the ranging program (8 ultrasound bursts at 40 kHz) in order to obtain an echo response. So, to create our trigger pulse, we set out trigger pin high for 10uS then set it low again. (TRIG, True) () (TRIG, False) Now that we’ve sent our …

Interfacing HC-SR04 Ultrasonic Sensor with Raspberry Pi

· HC-SR04 is a commonly used module for non contact distance measurement for distances from 2cm to 400cm. It uses sonar (like bats and dolphins) to measure distance with high accuracy and stable readings. It consist of an ultrasonic transmitter, receiver and control circuit. The transmitter transmits short bursts which gets reflected by target and are picked up by the receiver. The time ...

50 of the most important Raspberry Pi Sensors and Components

The HC-SR04 sensor is not a distance / motion detector, but an ultrasonic sensor. Through a small trick it is nevertheless possible to measure distances. By measuring the time elapsed between transmitting and receiving an ultrasound signal, you can derive the distance as the sound velocity in the air is known. In the tutorial I explain the details. The wide opening angle is an aspect which ...
