Design and Implementation of an Automatic Sun Tracking Solar Panel without Light Sensors

A B S T R A C T

Solar energy is one of the most commonly used types of renewable energy in areas that experience a lot of sunlight annually. Most solar panels are installed in a stationary position where they receive solar radiations from the sun. But still,  there is a lot of solar energy that escapes as the sun rises and sets. Two stepper motors are used for dual axis movements of the panel, as it seeks for points where sunlight energy is highest. One motor tilts the panel through an angle of 45° on the vertical axis and the second motor will rotate the panel through a 360° angle at a point on the horizontal axis. The control circuit which is programmed to give a signal to the stepper motors to rotate after a given time so that the solar panel can track the sun, and then give voltage signals to the controller. The messages are compared and the maximum voltage is the point where the
panel will be stationed for a particular period of time.

Design and Implementation of an Automatic High-Performance Voltage Stabilizer

A B S T R A C T

This research aims at the design and implementation of an automatic high-performance voltage stabilizer which helps to detect inappropriate voltage levels and correct them to produce a reasonably stable output. The system consists of five dependent architectural designs which involve the power supply, delay switching circuit, monitoring circuit and load changeover circuit using 555 ic which produces the required signal when switched on by a relay to activate the alarm. The system uses a relay to charge the batteries and automatically switches on this supply to supply the loads. It is composed of switching transistors and relay to control the power provided to ac loads, and it has LEDs for indicating the state of the system, 240-220vac/120-110vac switch, voltmeter displaying load voltage, heatsink, and fans for cooling the system. The system protects electrical equipment and machine against voltage surge.

Patient Medication Reminder Circuit Using ATMEGA328/P Microcontroller

A B S T R A C T

This project patient medication reminder is a system which helps in medication administration and monitoring. This system consists of an ATMEGA328P microcontroller with an inbuilt EEPROM and a real-time circuit. This system is driven by an embedded program that inputs predefined parameters which are processed based on the input variables entered via a user interface device such as the keypad. All the entries made on
the keypad are concurrently and simultaneously displayed on the LCD panel of the device. The logic for the processing is built into the embedded program to initiate the alert through an audio alarm. Not only does it have an alarm system, but also an LCD which displays the medicine to be taken at the reminder time.

Obstacle Detection and Avoidance Irrigating Robotic System

A B S T R A C T

The project is designed to build an obstacle detection and avoidance irrigating robot to optimize water usage for crops using the ultrasonic sensor for its movement. A micro-controller (ATMEGA238) is used to achieve the desired operation, and a Water Pumping System

mounted on the robot to irrigate the entire farmland. A robot is a machine like a human being that can perform the task automatically or with guidance. Robotics is a

combination of computational intelligence and physical devices (motor). Computational intelligence involves the use of programmed instructions.

The autonomous irrigating robotic system is a cost-effective, portable, compact and easily maintainable system that helps farmers to irrigate their farmland.

Automatic Power Supply from Four Different Source Using Microcontroller

A B S T R A C T

This project is designed to automatically supply continuous power to a load through one of the four sources of supply that are: solar, mains, thermal, and wind when any one of them is unavailable. The four switches represent the four causes. The switches are connected to an 8051 microcontroller of which they provide input signals. Whenever a switch is pressed, it shows the absence of that particular reference. A relay driver is used that receives microcontroller generated output and switches that specific relay to provide continuous power supply. A lamp or bulb is used as a load for demonstration purpose which draws power from main. When the primary fails to supply power, automatically next available source is used like thermal. If thermal fails then the next one is used and so on. An LCD is used to show which power supply is on.
