3. GSM MODEM

Provides full functional capability to serial devicesto send SMS and data over GSM network.

Supports popular AT command set so that userscan develop applications quickly.

4. MAX 232

Used to convert TTL/RS 232 and vice versa.

Standard voltage range of RS 232 pin is -15 to +15 v.

POWER SUPPLY

Required DC power is derived from the AC main using a transformer,

rectifier, filter and voltage regulator The voltage is rectified using the bridge rectifier The ripples are removed by capacitive filtering. To provide a stable voltage voltage regulator is used

Algorithm

Step 1: Start

Step 2: Initialize baud rate

Step 3: Enable transmitter and receiver

Step 4: Initialize ADC and select channel 0Step 5: Enable ADC

Step 6: Check whether ADC conversion is completedor not if completed go to step 6

Step 7: Store the valueStep 8: Transmit to UART

Step 9: Stop
