21、oller and Gnd is connected to 20th pin of microcontroller. Pin 2.0 to pin 2.7 of port 2 of MC is connected to data pins i.e., D0 to D7 of LCD display. Pins 4, 5, 6 i.e., RS, RW, EN. Of LCD are given to p 0.0 to p 0.2 o

22、f port of 0 of MC. Pin 3.0 and pin 3.1 of port 3 of MC are connected to pin 11 and pin 12 of Max232. Pin 3.3 of port 3 of MC is connected to pin 5 of Opto coupler. Pin 1 & 2 of Opto coupler are connected to energy

23、meter. Pin 14 & 13 of Max232 are given to pins 2 & 3 of DB9 male connector. Pin 2 & pin 5 of DB9 Female Connector are given to GSM modem. 4. Result Analysis The AT89S52 is Atmel's derivative of the 8052.

24、 It is compatible with Atmel's In-System Programming (ISP) via an on chip SPI interface, which allows it to be programmed via Atmel's AT89ISP programmer while the MCU is in the target circuit. Intel has provide

25、d evidence that substantiates that 89S52 has a faster programming time than 8051.Therefore, in short the basic advantage between 8051 and 89S52 is the difference in ROM memory. Atmel 89S52 also has advanced (flash) EEP

26、ROM. Fig. 2(a) and Fig. 2(b) show the comparison results with respect to features and performance respectively. 5. Conclusion The SMS based electricity energy meter billing system using GSM modem was implemented, to let

27、 the consumer know electricity bill has reached a certain threshold. It informs the customer through a SMS sent on the mobile through the GSM modem attached to it. The system consists of the electricity meter which mea

28、sures the electricity bill and informs the consumer about the number of units consumed and associated costs with it. The microcontroller coordinates the whole system with the help of its different components connected

29、to it. This embedded system can further be developed to measure more complex and high voltage systems which consume a high load of electricity and energy. The information transmission can be extended to include other i
