The existing energy meter reading technology uses man power which has disadvantages like errors during calculation, absence of consumer during billing time and extra expenses for the billing process. The wireless energy meter monitoring system aims to minimize these difficulties by providing energy meter monitoring through wireless medium. Power consumed by consumer in the home side module is monitored by Electricity Board through wireless technology. This wireless technology is implemented by using ZigBee modules. This is done by using a ZigBee transceiver interfaced with both the PC (Electricity Board) section as well as the consumer side. The Microcontroller based system continuously records the readings. These live meter readings are displayed in the LCD and also sent to the PC side through ZigBee. The -PC (Electricity Board) takes the responsibility of calculating the bill with the data received from the home side, and the tariff provided by the operator and displays the same in the LCD placed in the consumer’s home by transmitting the data through ZigBee transceiver.

 

The major features of this project are:

• This system enables the Electricity Department to read the meter readings regularly without the person visiting each house.
• Also, this system helps in monitoring the energy meter readings on general purpose PC.
• This can be achieved by the use of Microcontroller unit that continuously monitors and records the Energy Meter readings in its permanent (non-volatile) memory location.
• Zigbee based Wireless transmission.
• Automatic tariff calculation.

The major building blocks of this project are:

• Regulated Power Supply.
• Microcontroller.
• Zigbee modules.
• Energy Meter.
• Optocoupler.
• PC.
• LCD displays with driver.
• Reset.
• Crystal oscillator.
• LED indicators.

Software’s used:

1. PIC C Compiler to write the program.
2. Embedded C language.
3. Express SCH for Circuit design.
