DAQ System with Beaglebone Black using serial communication

This repositori contains C code to implement a DAQ system with a Beaglebone Black using serial communication with sensors. Sensors used in this system are: GC-0017 (Cabron dioxide), CM-31910 (Carbon monoxide, and temperature) and OX-0052 (Oxigen).

Installing

To get this repositore you just need to clone it into your Beaglebone Black

git clone https://gitlab.com/sayeth.rd/daq-serial-bbb/

Utilization

Configure UART1, UART2 and UART4 ports with this command

config-uart-pins.sh

Connect sensors to power supply and Beaglebone like in the next diagram. Diagrama conexiones

Then you can run the code wih this comand*:

./daq <daq duration(h)> <sampling period(s)>

*replace <daq duration(h)> with the total data acquisition time (in hours), and <sampling period(s)> with the time between each measurements acquisition (in seconds).
