Wired listed D-tect Systems’ radiation detection device, Rad-DX, as one of the first commercial products to use the super-lightweight open source Contiki operating system/mesh network.
Rad-DX units are area radiation monitors that use sensitive scintillation detectors to detect even faint sources of radiation within 1 second. They are set up in fixed locations where radiation threats may occur and automatically form an intelligent, self-healing mesh network called D-tect SensorNet, which D-tect developed using Contiki as a base.
SensorNet allows Rad-DX units to be constantly connected to each other and to the user network. It supports up to 50 Nodes, which can be helpful when monitoring large areas. It can also be used to collect radiation readings, configure nodes, and perform firmware updates. But even with these updates, D-tect engineers were able to constrain SensorNet’s RAM usage to less than a megabyte.
DX-View Software enables device monitoring through a PC, when connected to the SensorNet network and D-tect's online web portal, DX-Dashboard, enables device monitoring from any tablet or computer, when the devices are connected to the internet via Wi-Fi or Ethernet.
MiniRad-DX units can also be connected to the network using the same SensorNet technology and monitored through DX-View and DX-Dashboard. They are smaller radiation detection units that are designed to be carried by the user and can be used for precise radioactive source location.
