SL:Introduction

The Sensor Lab can be found in room 1.101 of the IfI.

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.

A number of sensor boards are available, such as the MTS400 board, which includes 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

A full list of available hardware will be put here soon.

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.

Installation

Debian

SL:Install TinyOS 2.1 in Debian (lenny)

Ubuntu

The PCs in the sensor lab room are currently running Ubuntu 10.04.

TOSSIM

TOSSIM version in Tinyos 2.1.1 requires Python 2.5.5, which is not available in Ubuntu 10.04 (only newer versions are available). The following has been used successfully to install a compatible Python version:

sudo apt-get install build-essential gcc
cd Downloads
wget http://www.python.org/ftp/python/2.5.5/Python-2.5.5.tgz
tar -xvzf Python-2.5.5.tgz
cd Python-2.5.5
./configure --prefix=/usr/local/python2.5
make
make test
sudo make install
sudo ln -s /usr/local/python2.5/bin/python /usr/bin/python2.5
sudo ln -s /usr/local/python2.5/bin/python-config /usr/bin/python2.5-config

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
