Whenever any person enters the room then the counter will be increased by one then the light will be turned ON automatically. The main concept of this project is to control the room lights & counting the visitors within the room precisely. This project is used to design an automatic room light controller system through a visitor counter using ATmega16 Microcontroller.

AVR CONTROL SYSTEM ANDROID

This project is implemented by using AVR ATmega8 microcontroller to control different electrical devices in your home such as fan, light, etc with the help of Android supported devices like phones, tabs, etc by sending instructions through Bluetooth.Īutomatic Room Light Controller with Visitor Counter Based on ATmega16 Microcontroller AVR Microcontroller Based Electrical Devices Controlling Using Mobile

In this way, it will become very simple to check & control the system. When the light is turned OFF, the sensor like LDR detects & the bulb will start glowing. The soil moisture sensor is used to detect the level of water level because once the water level reduces then the pump will turn ON. If the temperature level goes high DC then fans will turn ON and similarly, fans will turn OFF once the temperature goes low. The temperature sensor is used to detect the temperature level. The required components used in this greenhouse control system are Atmega328 microcontroller which includes different sensors like temperature, light, soil moisture, and LCD, Pump, LDR, Bulb, and 12V DC fan. The proposed system implements a system by using different sensors for monitoring as well as controlling the environment of the greenhouse. AVR Microcontroller Based Greenhouse Controlling and Monitoring System So the microcontroller notices the output of the sensor so that it will turn ON /OFF the buzzer and sends an SMS to a predefined number. Once the sensor detects any LPG gas then its output will become low. The detector unit of LPG gas can be arranged simply into a unit to generate an alarm once it detects the gas. This gas can be detected by using a sensor like an ideal gas sensor. The dangerous LPG gas can be generated in the service stations, cars, storage tanks, etc. This project is used to design an LPG gas detector using an AVR microcontroller. LPG Gas Detector Based on AVR Microcontroller In the given figure motor is replaced with a lamp load for indication purpose.

AVR CONTROL SYSTEM PASSWORD

When this password matches the ATmega microcontroller sends the control signals to the relay to operate the motor otherwise it gives a buzzer alarm. This data further sends to the microcontroller where the password entered by the user compared with a stored password in it.

When the user enters the correct password in the android application upon a Graphical User Interface (GUI) in any smartphone, the Bluetooth modem attached to the circuit receives it. Here Bluetooth modem accepts the user input signals and correspondingly sends it to the microcontroller. The figure shows the block diagram of a garage door opening where the ATmega microcontroller acts as a central controller which accepts the input commands from the user to control the motor to open or close the door. Garage Door Opening using the ATmega Microcontroller The AVR microcontroller projects are discussed below which are very helpful for electronics engineering students.
