This document outlines a TinyOS programming course lesson on sensing. The lesson introduces using sensors in wireless sensor networks and provides exercises for students to retrieve sensor data from nodes, parse the data using a Netbeans project, and optionally combine radio interfaces to parse messages from other nodes as well as build a multi-hop application. Students are encouraged to work through the exercises step-by-step using provided code from previous lessons on serial communication and radio interfaces.

3. We have not yet used the sensors!
And that is the important feature ofWSN, the ability to
capture real data from the environment.

Let’s look at Lesson04 and go step by step!

7. 1. Merge code from Lesson 02 (Serial Communication) and retrieve
data from the sensors. Use the provided Netbeans project to parse
the data.
2. If you feel brave, combine the radio interface from Lesson 03 and
parse also messages from other nodes. Note: Find out how to
discriminate node ids.
3. Lets try and build our own multi hop application!
