How to calculate distance using ultrasonic sensor hc-sr04?
In this tutorial we will be using an ultrasonic sensor (HC-SR04). We are going to program our surilli with a basic program so we can calculate distance to an object the way bats do. The HC-SR04 Ultrasonic module has 4 pins: Ground, VCC, Trig and Echo.
What are the problems with the hc-sr04 sensor?
When the HC-SR04 sensor doesn’t have obstacles in front or when the obstacles are soft, it returns 0 or erroneous results. You can learn from this tutorial how to correct the false echo problems and make a more accurate HC-SR04 sensor. The accuracy of an ultrasonic sensor depends on the environmental temperature.
How to use only one pin of hc-sr04?
The HC-SR04 sensor uses one pin for Trigger and one for Echo. So you need to use two pins of your microcontroller to measure the distance detected by the sensor. In this tutorial, you can find how to use only one pin of the HC-SR04 to calculate the distance detected by the sensor.
What can an ultrasonic sensor be used for?
Calculate distance to a certain object using an ultrasonic sensor. It can be used for car distance alerts, security systems etc. In this tutorial we will be using an ultrasonic sensor (HC-SR04). We are going to program our surilli with a basic program so we can calculate distance to an object the way bats do.
