IOT Based Auto Power Supply Control from Four Different Sources to Ensure No Power Break


ABSTRACT
Auto supply switching is basically selection of supply from multiple available power sources automatically by using microcontroller concept that is to check the availability of the source and switching to that available source to ensure uninterrupted power supply to load. In case of the electrical appliance control using automation causes more safety.
Auto supply switching is a prototype for the same which is auto change to other source when main supply fails without human interaction in this system we are designing an embedded circuit to control and ensure auto supply switching. In case all 4 phases are available, then the switching will be in the default phase. Four relays are there to control the switching. As it is not feasible to provide all 4 different sources of supply, one source with alternate switches are provided to get the same function.
In this project 4 switches acts as 4 different source of supply. When any switch is pressed it shows the absence of that particular source which is connected to microcontroller as input signals. Here we are using ATmega328P microcontroller.
The output of ATmega328P Microcontroller is given to the 4 relays JQC3FC, which switches appropriate relay to maintain an uninterrupted supply to the load. The output can be observed by Bulb/Lamp. The switches can be switch ON and OFF by Wi Fi controller ESP8266. Due to this load can be operated at remote location through internet. On failure of the supply from first switch the load gets supply from the next available switch. If the supply from second switch also fails it switches over to the next available source and so on.

IoT Based Contact less Tachometer with Speed Control Using AVR Microcontroller and Hall Effect Sensor

Image
ABSTRACT Tachometer is device used to count the revolutions per minute of a rotating shaft. Generally tachometer makes direct contact with the rotating shaft. It will reduce the velocity of the shaft, giving faulty readings. Hence it is needed to measure the speed of rotating shaft without direct contact. This project describes a contact -less tachometer using AVR microcontroller ATmega328P and a hall affect sensor. This device can very accurately measure the rotational speed of a shaft without even touching it. This device is built on an ATmega328P microcontroller, an alpha-numeric LCD module and a Hall Effect sensor to detect the rotation of the shaft whose speed is being measured. In this project Hall Effect sensor acts as a digital counting device. It will detect any magnetic element passing in front of it and thus, will give an output pulse for each and every rotation of the shaft. These pulses are fed to microcontroller. Microcontroller counts the pulses coming from Ha...

Power Line Carrier Communication Using X10 Protocol

Image
ABSTRACT Most   electric   power   companies   employs   power   meter reader   to   collect   data   on   the customer’s energy consumption. Usually, this task is carried out manually, which can lead to high cost and errors, causing financial losses. This project has taken some approaches to minimize these problems. As in everywhere automation is required to reduce the work so we decided to implement to automatic meter reading using power line communication (PLC). Automatic meter reading (AMR) is the modern Power measuring device. It has advantages in safety, real time measuring and time saving as well as it has a better user interface and digital data analysis. Data is   send   over   existing   power   line   using   X10   protocol   that   reduces   the   complexity   and   cost   of system. In the latest generation of home automation systems, appl...
