Public Garden Automation

Description:
The most important problems faced are the misusage of electricity and its wastage. Sometimes due to carelessness of the authorities and the workers lamps are left ON which results in wastage of electricity. Water wastage is another problem which needs to be dealt with. Our project helps to overcome all these problems.

Firstly the Microcontroller around 4.00pm switches on the water supply once to water the entire garden few hours before opening of the garden for public. Next the gate is opened by running the motor which is driven by a motor driver operated by the Microcontroller. At around 6.00pm the lights are switched on depending upon the output of the LDR and the lights remain functional till the garden remains open for visitors.

The garden remains open for about three hours and so around 8.50 pm a buzzer is sounded to indicate closure of the garden and alert the visitors. The gate is then closed at 9.00pm and three of the four lamps are switched off. One lamp is kept on throughout the night. In the morning the remaining lamp is switched off as the depending upon the signal sent by the light dependent resistor to the Microcontroller. These are the step involved in the operation of the circuit and the public garden automation. Microcontroller is used to supervise the actions of all other devices and to control the entire set of operations.

Block Diagram Description: 1. POWER SUPPLY UNIT: Power supply unit provides a 5V regulated supply to the micro controller AT 89C51, ADC 0804, LCD, MUX 4051, serial memory. It provides a 12V unregulated supply to the relays. 2. LDR: The output of LDR is given as input to the signal conditioning circuit the output of which is given to 89C51 on input side to control the state of lamps. 3. MICRO CONTROLLER AT 89s51: It processes the calculated digital values by converting it to ASCII & sends it to the LCD display in order to display the data. Also depending upon the setting at the input, it controls the output 4. LIQUID CRYSTAL DISPLAY: As the name suggests, it is used for displaying purpose. It displays the current date, time.\ 5. RELAY: It is used to control the flow of water in the garden just like any simple valve and is driven by a relay driver. 6. KEYPAD: The keypad is used for entering the time and date and also can be used for manual over ride. APPLICATIONS: 1. This small scale project can be implemented in any public garden with minimum cost and resources. 2. This helps in proper utilization of the available resources and helps in avoiding wastage of electricity and water. FUTURE SCOPE: 1. This project mainly aims at the automation of the public garden to avoid wastage of resources. 2. This can be expanded in the sense of security. Using metal detectors and CCTV cameras security of the garden can be enhanced. 3. By using GSM technology further control of water supply and lights using mobile can be achieved Project Photographs:

Question and answers about this project:

Question: How much time will it take to reach project by courier?
Answer: Project PCB is ready, so it will take 2 days to complete the proejct. And then 2 to 3 days to courier the project.

Question: We want to add some extra features in this project like, automatic irrigation, temperature & humidity display, memory back up using eeprom and metal detector on gate. Is it possible?
Answer: Curretly this PCB does not have ADC (Analog to digital converter) so it will not be easy to monitor temperature and humidity. But yes, we can provide metal detector.
