Two common communication methods are powerline carrier communication (PLCC) and GSM. PLCC uses existing power lines to transmit data while GSM utilizes mobile networks. The document describes traditional electromechanical meters and advantages of automated digital meters. It also provides an overview of how AMR systems work including the use of encoder-receiver-transmitters connected to meters and data concentrator units that collect readings over PLCC. AMR allows more accurate billing and monitoring while reducing costs compared to manual meter reading.

POWER CONSUMPTION DETECTING AND ALERTING SYSTEMIRJET Journal
This document describes a power consumption detecting and alerting system. The system continuously monitors home appliance power consumption and calculates unit usage to alert consumers when they are close to exceeding the current electricity rate slab. When the slab rate threshold is reached, auxiliary loads will automatically be cut off and a message will be sent to the consumer. The system aims to help consumers efficiently use power from the grid and maintain a low electricity bill. It uses components like a microcontroller, relays, LCD display, step-down transformer, buzzer, and potentiometer. The system works by measuring power usage, calculating units, and sending alerts via buzzer and messages if the slab rate is approached or exceeded to encourage reduced consumption.

When a MAX232 IC receives a TTL level to convert, it changes a
TTL level to convert, it changes a TTL Logic 0 to between +3 and
+15v, and changes TTL Logic 1 to between -3 to -15v, and vice
versa for converting from RS232 to TTL
14. DB9
