Projects of AVR microcontroller

Introduction:
This project can be used to detect the LPG gas leakage. This project can be used in Industry where LPG gas is used. Or this project can be used in our home, because we use LPG gas in our day to day life for cooking purpose.
We have used LPG sensor to sense the gas. Output of this sensor is in analog form. And mircocontroller needs digital data for processing. So we have given output of sensor to the ADC of AVR. AVR microcontroller have an inbuilt ADC. PORTA of AVR acts as ADC input pins. Microcontroller will contineously monitor the sensor data.
When the sensor output crosses a predetermined level then microcontroller will give a high signal to the output relay. We can connect this relay to a buzzer or alarm or a LED. So whenever LPG gas level increases above a certain level then the buzzer will be turned on.

Introduction:
Parking is the main problem in today’s life. This is due to the increase in number of vehicles. Another main reason is insufficient parking space. But in past few years some multiplex and shopping malls have provided lots of parking space to avoid this problem. Generally this parking space is at Ground floor and 1 or 2 floors below ground floor. Multiplex and shopping malls have plenty of customers visiting often. Specially in festival season and on holidays.

Problems faced:
In current parking slots are improper or poor management. People have to waste their time searching for parking slots. They enter into long parking area and keep on searching for parking slots from one row to another and then to next. Sometimes they missed the obvious available parking slot

Our proposed Solution:
Our project, Car parking monitoring system aims to monitor these parking slots. We will provide sensor to sense whether the parking slot is empty or full. Then this data will be transferred from sensor to the AVR microcontroller which acts as central processing unit of the project. Microcontroller will then monitor these slots. As a output device we have provided a LED panel. This LED panel will have one LED for each parking slots. So if parking slot is empty then the LED will be turned on and if parking slot is full then LED will turned OFF. This LED panel should be fitted on the gate of Parking entrance.
When anyone enters the parking, he will see the LED panel on parking gate. Then he can understand which slot in which row is empty. Then he/she can directly enter to the respective row and can park directly to that parking slot.

Project Title: Monitoring and Controlling of Greenhouse environment using AVR microcontroller

INTRODUCTION:
This project is designed to monitor Temperature, Humidity, Light intensity, Soil moisture of the Greenhouse environment. Also this project is designed to control all these parameters. We have used sensors to measure various parameter. We have used Temperature sensor, humidity sensor and Light dependant resistor – LDR as light sensor. We have used 2 metal probes to sense the soil moisture. Output of all these sensors is in analog format, so we need a ADC – Analog to Digital converter. ADC will convert analog output to the digital data. We have used AVR series microcontroller in our project. We have used ATmega16 microcontroller. AVR has inbuilt ADC. So we don’t have to use external ADC because we can use internal ADC of AVR. So we have connected output of sensor directly to the ADC input pins of AVR. AVR has 10 bit ADC with 8 analog inputs to the ADC.

Thus AVR ADC reads sensor output and compares them with a predecided value which is stored in the AVR microcontroller program. Once the input value from sensor crosses set value then the microcontroller gives a high output to the relays connected to the output pins of the AVR. These relays are used to control the various parameters of the Greenhouse environment. User can connect the first relay to the fan to control the temperature. Second relay to the exhaust fan to control the humidity. Third relay to the water pump to increase the soil moisture. We have used Liquid crystal display (LCD) to display / monitor values. User can see the values on the LCD.

Project Title: Mobile controlled electrical devices using AVR microcontroller

Introduction:
Many times a situation occurs when we have to control various devices from a long / remote location. Consider following examples:
1) You are working in some industry and you have to reach at workplace at 8am to turn on some electrical device like boiler or conveyor belt.
2) In our normal day to day life we go out of home and forgot to turn off fan or lights inside the house.
3) In summer season we want to turn on Fan or AC — Air cooler before we reach home.

For all above situations, we need a device / controller which can turn on / off the devices.
So we can think about various controlling methods like Infrared remote, Radio frequency remote, GSM controlling by sending SMS or by Call based controlling
All the methods have their own advantages and disadvantages, but for the situations mention above we can use the best method which is Call based device controlling.

Description:
In this project we have to connect a mobile to the microcontroller circuit. We have provided six relays at the output of AVR microcontroller. Six relays can control any six devices. For demo purpose we have provided 3 DC devices which operate on 9 volt battery, rest 3 relays are kept open. Each device has been assigned 2 keys on the mobile. One key to turn on that devices and another key to turn off that device.
To start with working of the project, first switch on the power supply and then we have to dial a call from any other mobile to the mobile connected to the project. After the call is received at the other end then we can control the device. We have to press respective key to turn on / off the device. For example, when we press key 1 then the first device will be turned on. and when we press key 7 then first device will be turned off.
