gammaScout2MQTT

Linux / Raspberry C++ to send data from a Gamma Scout Online to a MQTT server

This application is running on a Linux operating system ideally like a Raspberry.

This software will collect data from a Gamma Scout Online using USB serial port, clean the data and sent it to a MQTT server.

Example

./gammaScout2Mqtt -h 192.168.0.10 Connecting to Gamma Scout... Connected to Gamma Scout Online. Connected to mqtt: 192.168.0.10:1883 Received: 0.169 Received: 0.169 Received: 0.175 Received: 0.175 Received: 0.163 Sending [192.168.0.10:1883]: 0.163 Received: 0.157 Received: 0.157 Received: 0.151 Received: 0.138

Tested with

  • Gamma Scout Online Hardware Version
  • Ubuntu 19.04
  • Raspbian (Raspberry PI Zero W)

Prepare to build it

You need to connect to the terminal.

Add the user that will run the application to "dialout" (allow access to serial port)

sudo adduser $USER dialout

First update the system

sudo su
apt-get update; apt-get upgrade; apt-get dist-upgrade;apt autoremove
reboot

If you are running a raspberry, update the firmware of the raspberry

sudo rpi-update
sudo reboot

Install some package to be able to build the application

sudo apt-get install cmake git

You can now clone the project

git clone https://github.com/gabrielklein/gammaScout2MQTT.git

Build it

The easiest way to build it is to run

./build.sh`

Or if you want to do it manually

mkdir build
cd build
cmake ..
make

You can get help using

./gammaScout2Mqtt --help

Usage

If you use the following command, data will be sent on the MQTT server 10.0.0.60, topic /gammascout/monitor

/gammaScout2Mqtt -h 10.0.0.60 -t /gammascout/monitor

Some other parameters

./gammaScout2Mqtt --help

./gammaScout2Mqtt Version 0.1

Read data from an online gamma scout and send it to a MQTT server

-?, --help: Display some help -v, --version: Display the version of this software -d, --device: Device to use, default /dev/ttyUSB0

Settings for MQTT -h, --host: Host, default 127.0.0.1 -p, --port: Port, default 1883 -u, --username: User name -P, --password: Password -s, --seconds: Send the value every s, 0 = as soon as possible, default 30 seconds -t, --topic: Base topic, default /GammaScout

Production

If you want to run it on a production system,

Exit your cron and add the following line

@reboot /{PATH_TO_GAMMASCOUT2MQTT}/start.sh &>/tmp/gammaScout2Mqtt.log

You can’t perform that action at this time.
