A NOVEL TECHNIQUE FOR TEMPERATURE AND MOISTURE MEASUREMENTS USING ZIG-BEE

[attachment=16884]
INTRODUCTION

we move on to WSN (wireless sensor network) which is one of the most significant technologies in the 21st century.

The systems are usually composed of large quantity of small sensors nodes.
The sensor nodes consist of three components: sensing, processing and communicating.

Each wireless sensor node communicates with a gateway unit which can communicate with other computers by Local Area Networks (LAN)

The applications that utilize WSN in paper, foil, and textile industries to measure temperature and moisture using ZIG-BEE.


Transmitter


Moisture and temperature sensor are used to sense the moisture and the current temperature of the surroundings.

The sensed signal is in the form of the analog signal.

ADC is used since microcontroller need digital signal.

Then the signal is send to the MC.

When the range that is already fixed in the MC has been crossed according to the sensed input then it transmits signal through the ZIG-bee Transmitter


Receiver

The sensed input then it is received using receiver ZIG-bee.

Then again the signal is applied to the micro controller then view the result through PC in Online.

ADVANTAGE

Data transfer is fast.
Two way communication.
Easy maintenance.
