BATTERY CHARGING MONITORING & CONTROL DEVICE USING INTERNET OF THINGS (IOT)

ABSTRACT

The project is based on the design and construction of a battery charging, monitoring & control device using internet of things (IoT). This device can monitor the battery charging (soc) and control it, will help vastly in reducing the wastage of energy also improving convenience. This system would be capable of turning on and off only when the device is connected and charge only when needed through an android application, and can be further improved to work in portable sizes to suit any need. In this work a PIC16F887 MICROCONTROLLER is the main controller of the device, the Webserver which was interfaced by an A6 GSM/GPRS MODULE acts as the IoT platform. As the webserver is platform independent, it is used on any device, like mobiles and laptops. The test results were power supply test, GPRS module test, switching circuit test and system test, from the power supply test, from the voltage regulators 7805 & LM317 produces 5V and 4.2V respectively which we got during the test, in the GPRS module test, the GPRS module communicated with the microcontroller, in the switching circuit test, each actuator pins of the relay were connected to power and ground to determine if the relays will actuate, while in the system testing we tested the entire circuitry and cross examined it for errors like short circuits, lead flux joining unwanted links, proper insertion IC pin layout and also checking of ICs and its pin numbers and cross examined once again before powering the system.
