ABSTRACT

Wireless Sensor Network for Industrial Applications using Zigbee

The main aim of this project is to continuously monitor the Industries for different

parameters such as temperature, Gas etc. These sensors are interfaced with ADC to give digital

output for the controller. The controller monitors sensor inputs continuosly and displays on the

LCD. The buzzer is also interfaced with the microcontroller to give alert whenever there is

critical situation. It also sends these parameters to remote computer wirelessly using Zigbee

Transmitter.

The same data is received by Zigbee Receiver which is interfaced with PC. The data is

then finally displayed on PC with necessary software. Zigbee Modules are interfaced with the PC

through MAX232 Interface.
