Substrate Sensor Agent

The agent works with SEN0233 sensor and publishes every interval seconds the measurements to Robonomics Network

roslaunch parameters

• interval - interval in seconds. Default is 30 seconds
• port - specifies the port where the sensor is. Default is /dev/ttyS0

Build

nix build -f release.nix

Launch

roslaunch substrate_sensor_demo agent.launch

NixOS Service

From the channel:

substrate_sensor.enable = true;
substrate_sensor.interval = 30;         # optional
substrate_sensor.port = "/dev/ttyS0";   # optional

or manually:

systemd.services.substrate_sensor = {
   requires = [ "roscore.service" ];  
   after = ["roscore.service" ];
   wantedBy = [ "multi-user.target" ];
   environment.ROS_MASTER_URI =  "http://localhost:11311";
   script = ''
        source /root/substrate_sensor_demo/result/setup.bash \
        && roslaunch substrate_sensor_demo agent.launch 
   '';
   serviceConfig = {
     Restart = "on-failure";
     StartLimitInterval = 0;
     RestartSec = 60;
     User = "liability";
     Group = "users";
   };
};
