The Sense/Stage MiniBee is a small, wireless sensor board, that can be configured and programmed based on the needs of its application.
The Sense/Stage MiniBee has 11 digital inputs or outputs (of which 6 can be used as PWM outputs) and 8 analog inputs. The board has holes for mounting pin headers to connect to these inputs and outputs. There is also a footprint for the LIS302DL accellerometer on the board. The board runs at 3.3V and 8 MHz.
The Sense/Stage MiniBee is made to fit an XBee or XBeePro chip for wireless mesh network communication in the 2.4 GHz range. It can receive and transmit serial data to this chip, and there is control over the sleep pin of the wireless chip, so energy can be saved by turning the wireless chip off.
There is example firmware for the Sense/Stage MiniBee with easy configuration to read out analog and digital data, and send out digital data or pulse width modulation. Or, use I2C to communicate to sensors, or read out ISP data. It can also receive and transmit serial data to the XBee chip at 19200 kbps.
The Sense/Stage MiniBee has been used in a network configuration with up to 35 nodes active at the same time in one room, both sending and receiving data.
