GSM vs. Other Communication Technologies Bluetooth Zigbee WIFI RF PLCC GSM Range 10 m 100 m 10 m Wire Dependent Signal Dependent Speed 1 Mb/s 250 KB/s 54 MB/s 100 KB/s 10 MB/s Low Power Medium Very low High Low Low Complexity High Low

Interfacing

Code Logic ADC reads value Convert it to digital value Send the Voltage value to LCD as output

Ammeter ADC reads value Convert it to digital value Send the Current value to LCD as output

Power Factor Meter Using OP-AMP as comparator When current wave form hits 0 value a timer starts When voltage wave form hits 0 it stops timer Time difference is calculated Through formula as shown before angle is calculated
