SL:Introduction

Nodes Hardware

The sensor nodes we have ordered are from Crossbow technology (http://www.xbow.com/Products/productdetails.aspx?sid=264) Basically, the sensors operate in 2.4GHz ISM band. The range of the radio module is about up to 50 m indoor and up to 300 m outdoor.

For more details see the data sheet: http://www.xbow.com/Products/Product_pdf_files/Wireless_pdf/IRIS_Datasheet.pdf

Sensor board: MTS400 including the following sensors

• Dual-axis Accelerometer: Analog Devices ADXL202JE
• Barometric Pressure Sensor: Intersema MS5534AM
• Ambient Light Sensor: TAOS TSL2550D
• Relative Humidity & Temperature Sensor: Sensirion SHT11

Modifications for iris motes

PacketParrot application

The PacketParrot application which is provided with TinyOS does not work on directly on the Iris motes. Thus, the following modified version can be used instead. The modifications are basically replacing the special radio component, which is used for sending and receiving, by the generic AMSenderC and AMReceiverC components.

PacketParrotC.nc

PacketParrotP.nc

Installation

Debian

Install TinyOS 2.1 in Debian (lenny)

VMWare

login to the set up computer

 user: wsn
 password: tinyos

start Xubuntos in VMWare-Player

 user: xubuntos
 password: tinyos

Test

Note: the motelist command does not show any connected motes (I think it is because of that the hardware is very new and therefore cannot be recognised)

To find out which usb device to use, just connect the node and use the dmesg command.

Transfer test application Blink to the node attached via USB

 cd /opt/tinyos-2.1.0/apps/Blink
 make iris install.1 mib520,/dev/ttyUSB0
