Project description
HC-SR04 Ultrasonic Sensor on Raspberry Pi
A simple module for calculating distance and depth measurements with an HCSR04 Ultrasonic Sound Sensor and a Raspberry Pi.
Install
sudo pip install hcsr04sensor
Description
The module does the following;
Returns an error corrected distance by using the median reading of a sorted sample.
Rounds the value to a specified decimal place.
Adjusts the reading based on temperature by adjusting the speed of sound.
Allows measuring distance and depth in metric and imperial units. See;
pydoc hcsr04sensor.sensor
Usage
See example scripts in https://github.com/alaudet/hcsr04sensor/tree/master/examples.
Access to Raspberry Pi GPIO pins require elevated priviledges. Run example scripts with sudo.
