Programming with the distance sensor (HC-SR04)

This tutorial covers how to write Python code to work with the HC-sr04 distance sensor. The distance sensor works by shooting ultrasonic waves, calculating the amount of time between sending the signal and receiving it. We can use this time, and our knowledge of the speed of sound constant to calculate distance. It should noted here that the distance sensor works well even on some slants, if ...

HC-SR04 Ultrasonic sensor and STM32 » ControllersTech

· How the HC-SR04 works. At the front of the HC-SR04 sensor, you can find two silver cylinders (ultrasonic transducers), one is the transmitter of the sound waves and the other is the receiver. To let the sensor generate a sonic burst, you need to set the Trig pin high for at least 10 µs. The sensor then creates an 8 cycle burst of ultrasound at 40 kHz.

Ultrasonic Sensor HC-SR04 with Arduino Tutorial - Arduino ...

Ultrasonic Sensor HC-SR04 is a sensor that can measure distance. It emits an ultrasound at 40 000 Hz (40kHz) which travels through the air and if there is an object or obstacle on its path It will bounce back to the module. Considering the travel time and the speed of the sound you can calculate the distance. The configuration pin of HC-SR04 …

Macduino: HC-SR04 : using multiple ultrasonic modules

· How to position the sensors It is important to dispose the two additional ultrasonic modules (HC-SR04 #1 and #3 in Figure 1) at fixed angles on an ideal circle of radius R centered in the origin. To be able to do that in practice, just place your sensor #2 and decide how much R should be. Take as the origin of the axis the point P that it is a distance R from sensor #2 on the normal wrt the ...
