ABSTRACT:
This application
describes a system for wind speed measurement and alert.This application is
implemented with the help of two sections one is transmitter section which is
responsible for monitoring the environment temperature using temperature sensor
and depending upon the variation in temperature the speed of the wind changes
automatically and whatever the temperature is changed in the transmitter section is displayed on
the 16x2 LCD and parallely is is transmitted to the receiver section and
displayed on the PC using Zigbee communication.In the transmitter section the
temperature sensor is connected to the LPC2148 controller and this controller
is responsible for manipulating the entire application.
The LPC2148 are based on a 16/32 bit ARM7TDMI-S™ CPU with real-time
emulation and embedded trace support, together with 128/512 kilobytes of
embedded high speed flash memory. A 128-bit wide memory interface and unique
accelerator architecture enable 32-bit code execution at maximum clock rate.
For critical code size applications, the alternative 16-bit Thumb Mode reduces
code by more than 30% with minimal performance penalty. With their compact 64
pin package, low power consumption, various 32-bit timers, 4- channel 10-bit
ADC, USB PORT,PWM channels and 46 GPIO lines with up to 9 external interrupt
pins these microcontrollers are particularly suitable for industrial control,
medical systems, access control and point-of-sale. With a wide range of serial
communications interfaces, they are also very well suited for communication
gateways, protocol converters and embedded soft modems as well as many other
general-purpose applications.
This project uses two power supplies, one is regulated 5V for modules
and other one is 3.3V for LPC2148. 7805 three terminal voltage regulator is
used for voltage regulation. Bridge type full wave rectifier is used to rectify
the ac out put of secondary of 230/12V step down transformer.
