The Sensor Node is the big daddy of all the nodes in the GammaNet system. it host an array of sensors from 2x Geiger Muller Tubes, Temperature and Humidity Sensors, Air Quality Sensors, Barometric Air Pressure Sensor, Rain Sensors, Rain Water Level Sensor, Wind Speed and Wind Direction Sensors. At the moment there are only designs for Pole Mounted versions, however designes ar being thoguht up for a Ground Type station for being placed on the ground.

The Sensor Node has the following Electronics enclosed in a waterproof enclosure from Schnider Electrics and mounted on a 3mm Waterjet cut Aluminium frame, all electrics are mounted on 3D printed PLA metrial and all electronics are commercially available off the shelf components.
