Ubi-Sense1: Sensors Module (Under Development)
The initial version of the sensors module has sensing elements to measure / sense tri-axial acceleration, smoke, temperature, relative humidity and light. Tri-axial acceleration measurement is based on LIS331DLH from ST microelectronics which has a range of ±2g to ±8g and sensitivity of 0.9 mg/digit .The device can operate from -40°C to +85°C. This device supports both SPI and I2C output interfaces. Accelerometers find application in seismic / vibration sensing, anti-lock braking system (ABS) etc. The device MC145012 from Free Scale semiconductor is photoelectric smoke detector. The device operates in the range of -55 to +125°C. Smoke detectors enable early detection and warning of fire. It gives out analog output which can be connected to ADC for further processing and control. This board has ambient light (Infrared and visible) detector sensor from TAOS. This device operates in the range of -40 to +85°C. Its gives a voltage in the form of digital output using a proprietary standard two wire communication. The sensor board has got temperature and relative humidity sensor SHT75 which has the resolution of 12 bit relative humidity and 14 bit for temperature. This device operates in the range of -40 to +123.8°C. It gives digital output following SPI serial communication standard.

Ubi-Mote1:CC2430 based Wireless Sensor Node
Ubi-Mote1 is based on TI CC2430 SOC based device with 8KB RAM and 128KB Flash. USB-VCOM interface has been provided for host PC interface. This node contains on board humidity and temperature sensor and SMA connector for interfacing 2.4 GHz SMA antenna. A 10 pin SoC debug connector is povided for programming and debugging the node. External sensor interface is through two 10 pin expansion connectors. The application developing environment contains standard low power protocol stacks namely Zigbee and 6LowPAN.
Ubi-Mote2: MSP430 based wireless sensor node

Ubi-Mote2 is based on TI’s MSP430F2618 industry standard 16-bit Ultra Low
Power Microcontroller and TI’s CC2520 2nd generation IEEE 802.15.4 Radio Transceiver. The radio transmission has options for SMA / PCB antenna / chip antenna. The MSP430F2618 has in built 8KB RAM, 116KB Flash and comes with configurable peripherals such as 48 GPIOs, 12-bit SAR ADC, DAC, UART/SPI/I2C and operates at 16 MHz. The board can be interfaced with any daughter board with Sensors using 2 x 20 berg connectors. It contains on board MEMS based Humidity Sensor and JTAG Connector for Programming and debugging. The node can be powered through 2xAAA / 5V DC Jack / USB Connector.
