It is replaced by the direct supervision of the human. It also focuses on the Generic Architecture which can be applied for many other Automation Application. Vertical farming is a building where plants are grown in stacked fashion in a controlled manner. Nowadays due to industrialization and less availability of land there is a huge need to construct the Vertical farming which will be restricted mainly for growing plants. As the technology has become advance, we can control and monitor the multiple farms using IOT via internet from the central location. The purpose of this project is to monitor and control the environmental parameters such as temperature, moisture and the intensity of light using sensors. All this data is sent via internet to the server so the user can access it at any time. By controlling the temperature managed by the intensity of LEDs and the automatic moisture detection plant will get water at the right time in the right amount which will cause the good growth of the plants.

This project aims at applying a warning system to prevent accidents which involve vehicles such as cars and trucks when the driver is drunk by using the detection of breath alcohol detector’s concept or, more commonly known as a breathalyzer system that can monitor the person's blood alcohol concentration. This system detects the presence of alcohol molecule in the driver blood sample and displays the results by referring to the alcohol concentration detected from the driver’s blood once the driver wants to start driving the vehicle. A research on Blood Alcohol Concentration (BAC) showed that at 0.2mg/l and above, (measured in mg of alcohol per 100ml of blood, or mg/l) judgment, coordination and sensory perception are impaired, reaction time slows, performance in intellectual tests falls, and eyesight are weakened. Drunken drivers have increased very large and so are the deaths and accidents due to drunken drivers. The main objective of this project is to design a system which would prevent drunk drivers to start their cars when they are in drunk condition or to stop their cars in case they were already driving before getting drunk with SMS notification and vehicle tracking on Google Map. By so doing, reducing the mortality rates due to road accidents. The design of this project includes the development of hardware and software as the device modules. The hardware part includes the power supply units, the sensor circuit, the ATMEGA Microcontroller circuit, the LCD screen, motor unit, LED circuits, Buzzer as the alarm circuits, a GSM module, a GPS tracking module and an SD card module. Software part will cover coding programming in the ATMEGA microcontroller by using Arduino programming. During testing, the alcohol detector detects the presence of alcohol from the blood sample of the drunk driver. This blood sample is analyzed and displayed on an LCD screen in units of the Blood Alcohol Concentration (BAC). Based on the values that have been detected, this system operates and gives warnings to the drunk driver who is in drunken condition not to continue driving the vehicles via alarm from buzzer and LED will show the BAC level high. Equally, the LCD screen will display a message for the other persons in the vehicle. In case the drunk driver continues driving, the motor of the vehicle will stop rotating, causing the vehicle to stop. The GPS module receive the coordinate of the point at which the vehicle is located, and a series of message is sent through the GSM module to the Road Security Agency Service (RSAS) containing the link of the geographical coordinates (or location) of the vehicle. At the same time, the microcontroller and the SD card module is used to send drunk drivers and vehicle’s informations to the Microsoft Excel database for managerial purposes by the agency. Finally, the system was designed, and the real time implementation was done with a prototype of the model, and this system is effective, reliable, fast, at a distance measuring system that can be easily housed in vehicles.

GSM based Wireless Notice board is proposed in this project, the system is attended to be interface with user by using GSM technology with SMS messages, the user can sent the content to be displayed in the SMS and then the message will be display and shifted. The main processing unit used is Atmega328 microcontroller which dedicated with Arduino UNO board, shift registers are used to scroll the text in the screen from right to left, GSM module is used to enable cellular network functionality and SMS feature. The system was developed in prototype circuit and PCB circuit is also implemented with the help of Proteus PCB layout designer.

Notice Board plays a vital role to convey any message with the advent of digital technology. It is efficient to represent the information on digital devices. It is mandatory to use the digital media rather than use the conventional media like paper printing. This project is mainly about with Bluetooth in which there is an android application that is connected with LED display via Bluetooth. The message received by Bluetooth is send to microcontroller that further displays it on notice board. The notice board and LED display interfaced to microcontroller, powered by regulated power supply from main supply of 230v AC supply and solar energy.
