Solar Tracking System

Solar energy is coming up as a major source of energy. The need of the hour is renewable energy resources with cheap running costs. With the current systems for solar energy harvesting, we have high production only at fixed times mostly noon. ... This project proposes a dual axis solar tracker system that increases the productivity by a significant margin. The angle of inclination ranges between -90° after sun rise and +90° before sunset passing with 0° at noon. This makes the collected solar radiation to be 0% at sunrise and sunset and 100% at noon. This variation of solar radiations collection leads the photovoltaic panel to lose more than 40% of the collected energy. In this project, we take you through designing a Solar tracker so that you maximize on the solar energy collection. This device tracks and moves its solar panel in the direction of solar energy. Thus to increase the efficiency of solar panel, we will track the daytime and make solar panel move according to the sun radiation.

Line Follower Robot

A line follower is a simple robot that follows a thick line drawn on the floor using infrared (IR) or some other optical sensors. With day to day evolution in technology, human intervention is reduced is every field. ... Line follower can follow a specific path and will only follow that path. We use sensors to detect the path and write some code to control the rotation of motor so that it moves only in a specific path. When robot is placed on the fixed path, it follows the path by detecting the line. The robot direction of motion depends on the two sensors outputs. When the two sensors are on the line of path, robot moves forward. If the left sensor moves away from the line, robot moves towards right. Similarly, if right sensor moves away from the path, robot moves towards its left. Whenever robot moves away from its path it is detected by the IR sensor.

Street light covers vast area geographically, so it becomes difficult to turn it on or off daily. ... LDR is a device whose resistance can be controlled depending on the amount of light. Also, it becomes very efficient to exactly turn on the street light when it is required the most. We can make this possible by using LDR and turn it on or off depending on the intensity of daylight.

Traffic Light Wiring

Traffic Lights are used to control the vehicular traffic. In the modern era, everyone has different types of vehicles resulting in rise to the numbers of vehicles. That’s why traffic lights are mandatory to avoid the traffic jams and accidents. ... There are three lights in the traffic signal, having different message for the drivers. Red light (upper one) asks the driver to yield at the intersection, green light (last one) gives the driver free license to drive through the intersection whereas the yellow light (middle one) alerts the driver to wait if the next light is red one or get ready to go / turn the engine ON if the green light is next. Traffic light has proved to be an amazing way to stop the vehicular collisions and control the traffic jams in today’s modern era where everyone owns the different types of vehicles. The fundamental idea of this simple electronic project is to control the traffic. It can be used to avoid the vehicular collisions and traffic jams. This project is just a one-way traffic controller, although it can be further modified as well.

Electronic Water Level Controller Device

The filling of water tanks have been done through electrical pumps in the recent. However, untimely turning off the motor pumps lead to less filled tanks or over flown water from the tanks causing wastage. ... In order to avoid such situations we can have an electronic water level controller which can monitor the water level and switch the motor pump accordingly. This device has two level indicators which work in harmony of a power switching relay. This relay is the one which connects the water pump to the mains power supply. If the system indicates that water level in the tank is Low, then the system turns on the power supply for the water pump. The pump remains till the system indicates the water level is low. Once the system indicates the water level as high and not low, the power to the water pump is switched off. It remains switched off till the water level is not again to the low level in the tank. With a reference level at the bottom we attach the rest two of the high and low level sensing wire terminals at their respective positions. At the time when water isn’t the high level the circuit triggers the low level LED and also the relay to turn ON the water pump. Once the water level catches up the high level, the high level indicator is turned ON and the relay is switched to turn OFF the water pump till the next low level trigger.

Overvoltage And Under Voltage Protection System

This project aims to build a system that monitors voltage and provides a breakpoint based low and high voltage tripping mechanism that avoids any damage to the load. Various industrial and domestic systems consist of fluctuation in the AC mains supply. ... There is a chance of damaging electronic devices that are quite sensitive to these fluctuations. So there needs to be a tripping system that avoids any damage to these loads. Our system consists of a tripping mechanism that monitors the input voltage and trips according to limits provides. Here we use a quad comparator IC with two more comparators to be used as window comparators to it. Well the system delivers an error as soon as the input voltage falls out of the window range. This trigger then operates a relay that cuts off the load to avoid any damage to it. We here use a lamp to demonstrate as a load. Well the system is also configured with an alarm that goes on as soon as tripping takes place.

Smart Burglar Alarm System

Burglary is an unwanted event that no one wants to happen their premises. However it is difficult for anyone to be alert at all the times to protect their premises. ... This simple device Smart Burglar Alarm helps in this situation by raising an Alarm when there is an unwanted intrusion in the secured premises. When an intruder steps in, the system activates an alarm connected to the system. By hearing the alarm the resident of the office / home can get alert about the intrusion and a possible burglary. The alarm sounds till the system is turned OFF or the wire loop is connected back. The principle of working of this project to sense the motion of someone entering thee house and then sending an alarm at secured premises.

Wireless Doorbell Calling System

Doorbell system conventionally have wired configuration which is laid across the home / office premises. This configuration fails in case of damage to the electrical lines or the expensive Bell equipment damages. ... The Wireless Doorbell Calling System can help evade both of these difficulties. We have two units in this project which are connected to each other through an RF link. The transmitter unit has a button attached to it for user interface. When a user presses this switch it is indicated to the system that a bell should be rang inside the house / office premises. This information is passed on wirelessly to the receiver unit which has a hooter attached to it. This buzzer is pulled high by the system to hoot and thus signifying a visitor at the door.The RF communication happens in a range of 9 metres in line of sight. When the button is pressed at the transmitter side it alters the signal that is continuously sent by the transmitter side to the receiver side. When this altered change in the signal is received at the receiver, its voltage level at the respective pin goes high this triggering the hooter or the buzzer attached to that pin. This sound of the hooter / buzzer remains ON till the switch is pressed on the transmitting side or the calling side. Thus we have an effective calling system which is simple enough and is also inexpensive.

Clap Based Fan Switching System

Automatic switching system are nowadays very popular in domestic as well as industrial scenario. In this project we have a DC fan connected to the system. ... The system is configured in such a way that by a particular action of the user ‘Clapping’ can cause the Fan to start and remain ON for a limited period of time.We have mic that acts as a transducer. This transducer converts the sound energy in its vicinity to electrical pulses. These pulses are amplified and given to 555 timer controller. If someone claps near the mic of the system the above stated series of events get triggered. This leads to turning ON of the Fan. Due to the timing configuration set in the 555 timer the Fan remains ON for a stipulated period of time. After that period the Fan turns OFF and waits for the next clap from the user.The Mic is biased in to the circuit in such a way that it doesn’t picks up noise signals from the ambience. These electrical converted audio samples are amplified from an amplifier stage. Once the received sample has a voltage level enough to trigger the 555 timer, the Fan turns ON. Due to the mono stable configuration of the timer the Fan remains ON only for a stipulated period of time. After this time passes the Fan turns OFF and waits for the next pulse from the Mic.

Automated Night Lighting System

Here we put forth a fully automated night lighting system that detects light condition and switches on or off a load/bulb based on the light intensity. ... The system uses a LDR along with 555 timer and relay based circuitry with AC load connection in order to achieve this result. As soon as the light intensity falling on the LDR drops below a certain level, the circuitry uses a 555 timer based circuit to drive a relay for specific time duration. This process keep happening over time and the load is switched on through a relay as long as there are night/low light conditions. As soon as lighting increases the system switched off the load to turn of the lighting. Thus we have a fully automated night lighting system.

Load Control System Using DTMF

The project aims at controlling various loads spread over a large area remotely by using DTMF concept. The DTMF command tone thus received from the phone causes electrical load switching. ... The project is useful for managing industrial, domestic or agricultural loads that extend over a large area. The project requires a DTMF decoder interfaced to audio output socket of the cell phone. Whenever a button on the keypad is pressed the frequency thus generated from it is received by the decoder and it converts the frequency into its equivalent digital code. A microcontroller of 8051 family is used which is interfaced to relays through relay driver IC. The digital code is then provided to microcontroller that identifies the phone commands and initiates the relays to actuate the respective loads by turning them on and off.

Induction Motor Speed & Direction Controller

Induction motors have been used widely in different fields ranging from domestic appliances to industrial machinery. This necessitates a speed control mechanism that is efficient and is also safe to use. ... Also the induction motor can be run in either of the two directions which is quite useful in many applications.Induction Motor Speed And Direction Controller Project serves this purpose of controlling the speed and direction of the induction motor. Induction motor runs through direct AC line the amount of power given to it decides to what RPM it does rotates. We can modulate the power of the AC line to vary the speed of the induction motor through AC driver circuitry. An Atmega family microcontroller is used to give PWM power to an opto-coupler which drives the TRIAC giving supply to the induction motor. Instructions to the microcontroller are fed through cell phone connection to the system. The cell phone provides DTMF signals to the system which the system understands and takes actions accordingly. As per the video, a button is used to increase the speed of the motor, a button to change direction and a button to decrease speed of the induction motor. One can observe the whole process as it happens on the LCD. In this way this project proves to be quite useful in handling an Induction Motor for its speed and direction.
