Water Level Controller using 8051 Microcontroller

Water Level Controller using 8051 Microcontroller project will help in automatically controlling the water motor by sensing the water level in a tank. This article explains you how to detect and control the water level in an overhead tank or any other container. This system monitors the water level of the tank and automatically switches ON the motor whenever tank is empty.

Propeller LED Display

Propeller is a term connected with a rotating object: motor or pump, and is used in this project. Propeller rotates a set of light-emitting diodes for displaying numbers, characters and symbols in a rotating manner that’s the reason why it is termed as a Propeller LED Display. Some of the features of Propeller LED Display include displaying messages in a typical manner..

Metal Detector Robotic Vehicle

Land mines buried under the ground causes threat to the lives and affect the economy of the nation. Detection and removing of these mines manually is a dangerous task, which may sometimes causes accidents. In such situations robots aid in detection of the land mines. Not only  land mines, these robots can be used to detect any other metals presented in the ground. This article explains the metal detection robot that uses RF technology.

Biometric Attendance System:

   Attendance systems are commonly used systems to mark the presence in offices and schools. From  manually marking the attendance in attendance registers to using high-tech applications and biometric systems, these systems have improved significantly. In our previous projects, we have covered few other electronic attendance system projects using RFID and AVR microcontroller, 8051 and raspberry Pi. In this project, we used fingerprint Module and Arduino to take and keep attendance data and records. By using fingerprint sensor, the system will become more secure for the users.

Line Follower Robot Using Microcontroller:

    A line follower is an autonomous bot that can follow a specific colour line painted on a surface of different contrast, such as white on black.Line-following robots with pick- and- placement capabilities are commonly used in manufacturing plants. These move on a specified path to pick the components from specified locations and place them on desired locations. Basically, a line-following robot is a self-operating robot that detects and follows a line drawn on the floor. 

Sun Tracking Solar Panel:

As the non renewable energy resources are decreasing, use of renewable resources for producing electricity is increasing. Solar panels are becoming more popular day by day. Solar panel absorbs the energy from the Sun, converts it into electrical energy and stores the energy in a battery.

Digital Temperature Sensor Circuit

Temperature sensors are widely used in electronic equipment to display the temperature. You can see the digital clock displaying the room temperature value. It is due to the temperature sensor embedded in it. In this project, I will show you how to design a Digital Temperature Sensor Circuit. In the process, I will explain two circuits: one using 8051 Microcontroller and the other using ATmega8 Microcontroller.

Bluetooth Controlled Electronic Home Appliances

Bluetooth Controlled Electronic Home Appliances is a simple project, where we can control different electrical appliances and electronic devices using an Android device with the help of Bluetooth Technology.

Wireless Electronic Notice Board using GSM​

We know the importance of notice boards in public places like railway stations, bus stations and airports. But changing notices day-to-day is a difficult task. This article explains you how to design a Wireless Electronic Notice Board using GSM technology. The project displays the data on LCD whatever we sent from the mobile.

Density Based Traffic Signal System:

  At the present time, the traffic control system becomes the main issue because of the fast increase in automobiles and also due to large time delays between traffic lights. So, in order to overcome this problem, we will go for density based traffic light timing control system. This article discusses how to control the traffic based on density.The proposed system uses IR sensors to calculate the traffic density. 

PWM Based DC Motor Speed Control using Microcontroller:

It is important to control the speed of DC motor in many applications, where precision and protection are essential. Here we will use a technique called PWM (Pulse Width Modulation) to control the speed of DC motor.

Ultrasonic Rangefinder using 8051:

In this project, we have built an Ultrasonic Rangefinder using 8051 Microcontroller and Ultrasonic Sensor. We have different ways to measure the distance. One way is to use Ultra Sonic Sensor or Module for distance measurement. This article explains you how to measure the distance using 8051 microcontroller. 

DTMF Controlled Home Automation System Circuit

Generally, appliances used in our home are controlled with the help of switches. These days, you can see many technologies used in home automation projects. This article presents the controlling of home appliances using DTMF technology.

Motor Protection against Single Phasing and Overheating

  The rise in temperature level of a motor during its operation beyond a permissible limit is known as overheating. The causes of motor overheating are motor overloading, distortion in the supply voltage, impaired cooling capability, unbalanced supply voltages etc. Because of overheating, we can face the problems such as Electrical fire, Insulation failure, Decrease in life time of motor due to earlier wear and tear of the motor winding's etc.

Advanced Wireless Power Transfer System

The project is a device to transfer power wirelessly instead of using conventional copper cables and current carrying wires. The concept of wireless power transfer was introduced by Nikolas Tesla. This power is made to be transferred within a small range only for example charging rechargeable batteries etc. For demonstration purposes we have used a fan instead of battery that operates by using wireless power.
