Company

• history, epfl
• Now named tinynode, after their flagship product 'tinynode'

Tinynode

• This board can be used with Sensorscope
• tinynode board, price 109 EU
• MSP430F1611
• XE1205

+15dBm

-121dBm

• 866MHz

Sensorscope

• Open source, TinyOS based project of EPFL University
• Sensorscope project is free and can be downloaded to Tinynode or MicaZ
• A mesh wsn system can be implemented
• Open source software is working and can be modified

Vehicle Detection System

sensor node, Obviously based on Tinynode

price 649 EU

Product only available for customers who have purchased a Vehicle Detection Starter Kit

Which costs 5999 EU

Communication range

   To another Vehicle Sensor: 30m LOS
   To a Network Repeater:     100m LOS
   To a Base Station:         200m LOS

Expected Range for Parking Nodes

• The range (30,100,200 m) is what the X1205 offers (866MHz 136dBm link margin)

Accounting that:

Sensitivity is one of the best in class

TX power can not be higher due to international and European regulations

The range expected to have from 866MHz technology is:

30m node-node

100m node-repeater

For 2400MHz Line Of Sight dependance is higher

Range expected to be less
