Sense-Box is created for applications requiring outdoor deployments. The platform is shipped with IP-65 certified box which can operate in a variety of weather conditions. The box contains Mahmote wireless mote. The mote can operate on its own for sensing environment data and communicating this data to a central server. This enables the system to be used as a rapid development platform where several sensors can be attached to the system for a wide range of applications.

The box comes with a TI cc2538/TI cc1310 based low power SoC coupled with a TI cc2592/TI cc1190 range extender which lets users to operate the sensor mote in a variety of transmit power levels. This is very useful especially when a particular node needs extra communication range to bridge the routing gap between two locations. The communication range of the box is improved further with a 5 dBi omni-directional external antenna. The box also supports power over Ethernet which enables an easy install via only a single Ethernet cable.
