A program to set instructions and get information from an SDS-011 running
on linux.
It has been written in C and contains a flexible command-line options.
A detailed description of the many options and findings are in sds011.odt
As part of a larger project I am looking at analyzing and understanding the air quality. I have done a number of projects on air-sensors. The SDS-011 sensor has been around for a longer time and there are many articles and drivers to connect to Arduino and/or from Python. However I wanted to create a C-language version to connect the DYLOS 1700 and SCD30 at the same time and compare the results. The challenge was larger than expected.
I have tested this on a Raspberry PI running Raspbian Jessie release and Ubunut 18.04. It has been adjusted and extended for stable working.
No dependency on other libraries
- Copy the files in a directory
- 'make' command will create an executable call sds
- To get help type ./sds -h
- to get output: connect the SDS011 to USB and type sudo ./sds -o
SDS-011 Options:
- -m get current working mode
- -p get current working period
- -r get current reporting mode
- -d get Device ID
- -f get firmware version
- -o get data (default : NO data)
SDS-011 setting:
- -M [ S / W ] Set working mode (sleep or work)
- -P [ 0 - 30 ] Set working period (minutes)
- -R [ Q / R ] Set reporting mode (query or reporting)
- -D [ 0xaabb ] Set new device ID
Program setting:
- -q x:y get data in query mode x times (0 = endless), y seconds delay.
- -H # set correction for humidity (e.g. 33.5 for 33.5%)
- -u device set new device (default = /dev/ttyUSB0)
- -b set no color output (default : color)
- -h show help info
- -v set verbose / debug info (default : NOT set)
- Initial version for Raspberry Pi and Ubuntu
- set reporting mode to query included in -q option
- set reporting mode to stream included in -o option
