SenseMote wireless sensors and actuators via Arduino

Wednesday, March 28th, 2012

SenseMote is an alternative firmware for the Ciseco XRF CC1110 module. It enables you to build wireless sensors and actuators via an Arduino-like sketch language. I believe that the gateway, the "sensehub", has a lower BOM cost than Nanode or any other open source wireless gateways and has more flexibility...

XRF 863.8 MHz radio to Ethernet Bridge

Monday, December 26th, 2011

Jobytaffey is designing an Ethernet to radio bridge. This prototype uses an ENC28J60 for ethernet, and an XRF radio module. The XRF module is a UART-controlled 863.8 MHz transceiver with 250 Kbps transfer rates. Via Flickr.
