Temperature Based DC Fan Control ECE Project Abstract

The point of the project is to outline a programmed temperature based fan control system that controls the speed of the fan. On the off chance that the temperature expands the speed of the fan additionally increments, and the temperature diminishes the speed of the fan likewise diminishes.

Mechanizing the on/off condition of a fan is valuable from numerous points of view it keeps the misuse of vitality when it’s not sufficiently hot for a fan to be required; it additionally makes it conceivable to screen situations that are not happy, or conceivable, for people to screen, particularly for broadened timeframes.

By interfacing a temperature sensor to a PolyBlock in Compare Mode, it’s very easy to turn on a fan when the incentive from the temperature sensor surpasses a given edge. Associating the fundamental segments for a Temperature Controlled Fan is clear. The thought is that the temperature sensor delivers a voltage that is corresponding to the temperature in degrees.

The project comprises of a microcontroller a temperature sensor ADC DC motored fan and a DC engine driver, the temperature sensor ADC and a DC engine driver are interfaced to the microcontroller. At the point when the framework is exchanged on the microcontroller empowers every one of its peripherals and begins perusing the information from the ADC and contrasts those qualities and the set predefined esteems if the temperature esteem surpasses the set predefined esteems then the microcontroller works the DC engine driver to expand the driving ebb and flow of the engine in order to build the speed and abatement the driving ebb and flow when temperature diminishes this shows the ADC esteems are straightforwardly corresponding driving ebb and flow of the DC engine, the DC engine driver is thusly associated with the DC engine.

In this way, we outline a temperature based microcontroller worked DC fan control.

Shared Steering Control between Driver and an Automation to avoid Accidents

AIM: The main objective of this project Shared Steering Control between Driver and an Automation to avoid Accidents when the driver is in fatigue State is to develop an embedded system, which is used follow a line and also giving a buzzer while any obstacle comes in the way.

IMPLEMENTATION: This Shared Steering Control between Driver and an Automation to avoid Accidents project is implemented 8051 based At89s52 developed board interfaced with Photosensors, ultrasonic sensor, H-Bridge driver, and motors.


DESCRIPTION: A car is having many capabilities. The car will do any number of tasks according to the program done by the controller inside. It seems a useless thing if it is uncontrollable. Here controlling a car is the main task has to consider while the driver is in fatigue state.

The car Platform employs two DC motors for the drive. In this project, the car will be followed a line up to the tracking object meanwhile any obstacle comes it will give a buzzer sound. After removing the obstacle it follows the line normally.

Since car Platform is equipped with two motors for the drive, controlling the motors, i.e. when making a right turn, the right wheel can be stopped i.e. power to the DC motor is switched off. The left wheel is driven i.e. left DC motor is on. This causes the system to take a right turn. Similarly for a left turn.

The detector circuitry consists of the ultrasonic integrated detection module. The detector houses the emitter as well as a detector. The detectors are positioned accurately either side of the line. They are placed such that they are just out of the line.

Micro Controller Based Drug Dispenser Project


With the present day environment, and with the work pressure the individual is carrying, it becomes highly impossible to take of a family member, who is undergoing therapy.

Sometimes it may be impossible to remember his/her own medicines and their time of consumption, thereby missing their medicine or the time of its administration.

In such cases, if any equipment is there which can give some sort of indication, to the individual concerned so that he can take his medicine. The same can be used even to use for other patients also.

In the present project, a microcontroller based drug dispenser is to be developed. The drug dispenser can be used to provide an indication of the medicine time, and it also dispenses the medicine to be consumed. The present project deals with a minimum of six medicines.

The doctor will prescribe each medicine time and dosage, and the same can be fed to the instrument, via a keyboard hooked up to the microcontroller. At the time when the said drug is to be consumed, the instrument provides the medicine (tablet or capsule) in the tray.

The medicine goes to the tray by rotating a motor, which dispenses only one tablet or capsule into the tray, and in the similar fashion all the drugs to be consumed are provided in the tray, and then the instrument provides the alarm.

The drugs and their timings can be programmed and can be easily programmed.

The instrument to be designed is to use an advanced microcontroller and needs to have an interface to a keyboard and also motors and sensors.

Microcontroller based Smart Parking Control System

This Smart Parking Control System project Designed With Microcontroller attempts to cut the time to park the vehicles in the lot and help the motorists to recall the exact parked space. Motorists often spend a significant amount of time to park their vehicles in the parking lots during peak hours. They also may not remember the parked space of their vehicle precisely, while picking up the vehicle.

To solve this problem, an automated vehicle parking system is designed which serves the motorist to find a space for his vehicle within less time. The system displays about the details of freed-up parking spaces. The waiting time to park the vehicle can be reduced by providing this vacant space information to the motorists before he/she enters the system.

The system recognizes the vacant space and displays automatically, this display system can be provided at the entrance of the main gate, so that while entering in to the parking space, the motorist can find his parking place without anybody’s direction.

To sense the vehicle at parking place, infrared sensors are used; the output of the sensors is fed to micro-controller and according to the received information from the sensors, the controller displays, that the particular parking place is vacant or full. For the demonstration purpose three sets of sensors are used to simulate three parking sites.

The system is designed such that, when all parking sites are filled and there is no space for another vehicle, automatically the gate will be closed. To simulate this, stepper motor is used and the controller drives the motor, a small arm of 10″ is coupled to the motor shaft, which simulates either the gate is opened or closed. For displaying the information LCD panel is connected at the output of micro -controller.
