Abstracts: Nowadays, The most important problems faced is the misuse 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. In most gardens, still the manual switching is done for various operations like control of light,water sprinkling,etc. Thus, we can control the garden activities using automation. By using automation, The manual work is reduced at great extent and energy consumption is also reduced. This system works on the real time clock. Firstly, the Microcontroller around 4.00 pm switches on the water supply once to water the entire garden 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 PIC Microcontroller. At around 6.00 pm 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 one of the two lamps is switched off. One lamp is kept on throughout the night. In the morning the remaining lamp is switched off depending upon the signal sent by the LDR, 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. Aim of this project is to make an efficient system for the automatic control of operations with power saving, by minimizing manual operation for the garden.
