Gsm Based Power Monitoring System For Dc Loads

DOWNLOAD ABSTRACT

AIM:

Design and Development of GSM based power monitoring system for DC loads.

PURPOSE:

DC loads consumes less power than AC loads. Especially DC lights and DC fans consumes less power with high efficiency. Sometimes they consume milliamps. But milliamps current reading is difficult. But we should read low current for battery based applications. Here we proposed solution like GSM based power monitoring system for DC loads.

DESCRIPTION:

This project includes GSM (Sim800C) module, which is connected to Arduino through UART. Two DC fans controlled by two relays which are connected to digital pins. Shunt resistor connected to Arduino analog pin. Voltage divider connected to Arduino analog pin which is voltage sensor.

WORKING:

In this project we will read voltage, current and power of DC loads. Here DC loads are DC fans. We can control DC fans with SMS commands. Current consumption is directly proportional to number of loads. If number of loads increase then power consumption also increased. We will get voltage, current and power information as SMS in two ways. Arduino sends SMS in time interval based and request based. Time interval means – every one minute it sends SMS. Request based means – by sending request SMS to GSM we will get voltage, current and Power information.
