Latest Projects Based on Ldr



The following projects are based on ldr. This list shows the latest innovative projects which can be built by students to develop hands-on experience in areas related to/ using ldr.

1. Wireless Switch Circuit Using CD4027

Wireless Switch Circuit Using CD4027

In our home devices are controlled with help of switches,sensor .Sometimes it dangerous if it physical contact with home appliances.To overcome these drawback the Light Dependent Resistor is replaced here so just pass the hand near to the LDR then the device is ON and to turn OFF again pass the hand above LDR is placed.

2. Electronic Eye Controlled Security System with IoT

Electronic Eye Controlled Security System with IoT

In the World of Security, Automated security systems are emerging technologies these days, Electronic eye is also called Virtual eye which is an electronic device, which observes whoever coming and going continuously. Let us assume, a door bell that automatically rings when a person visit your home and it can also be used for providing security when any person is trying to enter into your home without your permission. Through this project you are going to build a unique system which automatically rings the doorbell when there is a person standing in front of the door.

3. Fridge Door Alarm with IoT

Fridge Door Alarm with IoT

In this modern world, we all are enjoying the gift given to us by nature through the natural resources like Water and coal which is electricity. We cannot even imagine our life without power. Power is really the greatest power for us these days. Almost all household appliances, office machinery are running with the help of electricity. So, it is the time to do something for our environment by saving electricity. So, we must use it wisely and efficiently. Mostly in households appliances power is wasted from fridges in kitchen. Through this project, you are going to build a unique project that can remind you if you didn’t close your refrigerator completely with an alarm.

4. Automatic Door Opening and Closing System

Automatic Door Opening and Closing System

In Today’s World, Automation is one of the trending and emerging technologies these days. Every time when you enter a room, you need to push the door to open the door. Imagine there is a door which opens as soon as you come close to the door.

5. Dual Axis Solar Panel Tracking for Smart Irrigation

Dual Axis Solar Panel Tracking for Smart Irrigation

Through this project you are going to build an innovative project where smart irrigation technique with maximum power tracking technique through dual axis solar panel application.

6. IoT based Tampered Energy Meter Monitoring

IoT based Tampered Energy Meter Monitoring

Generally we have a very good system of measuring the power consumption. But the only problem is the energy used to measure the power consumption can be tampered. Through this project you are going to build a unique tampered energy meter monitoring based on IoT.

7. Weather Monitoring using Raspberry Pi

Weather Monitoring using Raspberry Pi

Weather Monitoring is a Project where you can see the change in the weather remotely using your smartphone, so the main conditions in the weather monitor are the temperature, humidity, and the air quality. Weather can change at any time as it is uncontrollable but it can be monitored continuously and measures can be taken depending on the weather conditions. In this project, you will be able to monitor the conditions of the weather and receive the data to your phone.

8. How to Build an Automatic Street Light Controller

How to Build an Automatic Street Light Controller

Did you ever think that how the street lights automatically turn ON in the night and turn OFF automatically at morning? Is there any person who comes to ON/OFF these lights? The following circuit that described below which perform this job automatically. This circuit employed the output from an uncomplicated light/dark activated circuit and oblige a relay in its output which can be further attached to switch ON/OFF a street light and electrical application in a household also.Automatic street light control is used to control the street lights(Turn on and off based on the light).

9. GSM Based Weather Report

GSM Based Weather Report

Weather Monitoring is a project where you can see the change in the weather remotely using your smartphone, so the main conditions in the weather monitor are the temperature, humidity, and the air quality. Weather can change at any time as it is uncontrollable but it can be monitored continuously and measures can be taken depending on the weather conditions. In this project you will be able to monitor the conditions of the weather and receive the data to your phone.

10. IOT Based Street Light Control

IOT Based Street Light Control

Street lightening is an essential infrastructure for cities in order to assure the security of citizens and goods. This infrastructure has however, a high economic and ecological cost. The work aimed at developing a low cost, low power microcontroller to adjust the light of LED street luminaires.

11. Vacuum Cleaner Robot

Vacuum Cleaner Robot

Technology changes everything; from the way, we eat food to how we run our homes. Automation has an impact on all walks of our life. The automation of our homes has made it easier for people to live and manage their households.

12. Electronic Candle

Electronic Candle

Candles are being used for light from ancient times. Before the invention of the light bulb, candles are being used for the light. They have been in use from ancient time. In recent times they are used in churches. Our project depends on electronic candles. Ordinary candles melt very fast and the place where they are used gets nasty. In this electronic candle project, we will make an electric candle with the help of an LED. It will be capable of turn on automatically during darkness and also shut down when they find some light.

13. Smart Energy Meter using GSM

Smart Energy Meter using GSM

In this project-based course you will develop a smart energy meter system using GSM technology which can send you updates about the energy consumption for a particular interval of time. You will be using an Arduino development board as a processing unit.

You can build this project at home. You can build the project using online tutorials developed by experts. 1-1 support in case of any doubts. 100% output guaranteed. Get certificate on completing.


14. GPS & GSM based Tracker

GPS & GSM based Tracker

In this project, you will build a GPS and GSM based Tracker using Arduino which can send continuous updates about the position on google maps in your mobile phone or computer. While building your project you will learn practically about the working of GPS modules, antennas, GSM modules and mobile communication.

You can build this project at home. You can build the project using online tutorials developed by experts. 1-1 support in case of any doubts. 100% output guaranteed. Get certificate on completing.
