1.1 Introduction

For this assignment you need to develop a simple fire detector. To keep it simple we define

a fire event as the excess of the two sensing parameters temperature and light levels.

You have to implement a control mechanism that checks both sensors on a mote and in

case that a certain threshold is exceeded, alarm has to be raised.

The main program should include the following features:

Control Loop, checking for temperature and light levels

Event Notification, sending a notification to alert the user that there is a fire event by

blinking LEDs and showing messages on the console.

The minimum requirement for this assignment is the successful implementation of the above

two features. However, to obtain a higher mark you need to implement further extensions

(see next Section).

1.2 Additional Implementations

Fire sensors and alarming systems have several requirements. In the following we describe

some of them that you may consider in your implementation:

Fire Sensors can be deployed in areas that are not easily accessible; therefore their

maintenance could be difficult. Because the sensors rely on battery energy, the

power consumption has to be kept low. Implement your control loop in a way that it

consumes less energy; for example by reducing the checking interval. You need to

show evidence to support your claim of energy reduction.

Apart from blinking LEDs and showing messages on the console, the sensor may

also notify a remote server when there is a fire event. For practicability and security

concern, your solution should use unicast for the communication.

Light and temperature level can vary from room to room and also change over the

time. Implement your program in a way that it adapts the thresholds for a fire event

before the initial control loop. For example, the measurements collected in the first 10

seconds can be used to set the threshold values. Or you can develop an advanced

mode that by pressing a button the sensor enters a recalibration phase for 10

seconds and resets the threshold values.

Add your own additional feature. However it has to fit into the fire detection scenario.

1.3 Assignment Hand-in and Marking Scheme (IMPORTANT)

You may submit a single PDF file (containing both programs) or two separate PDF

files. No other formats are allowed (including applying compression).1

Your submission MUST be in text format (not scanned images).1

You MUST include your name and URN at the beginning of each program. You may

do so by putting a comment before your code, e.g. /* Assignment 1, Name: Chuan

Foh, URN: 1234567 */.

We will print your code in grayscale. Use of coloured text is not encouraged.

You may use any libraries available in Contiki for your programming. If you use any

libraries, make sure you have good understanding of the usage and limitations. You

may be asked during the assignment interview.

Do not include unnecessary lines/text in your code, by doing so may reduce

readability.

The marking scheme will be uploaded, as a separate file, to SurreyLearn during the

semester.
