Automatic plant Irrigation (AT89C2051)

[Binu]

The Project presented here waters your plants regularly when you are out for vocation. The circuit comprises sensor parts built using op-amp IC LM324. Op-amp?s are configured here as a comparator. Two stiff copper wires are inserted in the soil to sense the whether the Soil is wet or dry.
The Microcontroller was used to control the whole system it monitors the sensors and when more than two sensors sense the dry condition then the microcontroller will switch on the motor and it will switch off the motor when all the sensors are in wet. The microcontroller does the above job it receives the signals from the sensors, and this signals operated under the control of software which is stored in ROM.

sir , plz let me know the type of sensors used in digital visitor counter, whether these are infrared sensors????????????


isha

[Binu]

The sensors are nothing but two metal rods, which are placed nearby with 2cm gap.

Hello Sir ,
I am the student of enggineering. I am select the project from your froum AUTOMATIC PLANT IRRIGATION so related this i want to know How to control the water level using microcontroller ???
Please send the details on my below E mail ID
godbolesn@gmail.com please send the programm for this in detail

hard work is sucess

[Binu]

Water level is not sensed by the microcontroller.
This project has 4 sensors which is used to sense whether the soil is wet or try. if more than 2 sensors are in dry condition then the motor is switched on and goes off until all sensors go wet.

Go to the projects page to download the program.

sir
give me the detail of sensors

[Binu]

The sensors are nothing but 2 metal strips, insert this metal strips into the soil.

sir are we considering here different kinds of soils or a single plant ,is soil resistance going to change as the plant is watered and accordingly changing the output
also are the four comparators for four different plants/soil conditions??

[Binu]

The 4 sensors are used to monitor 4 places. You can use it for a single plant or more.
The sensors will check the soil for wet or dry. You can adjust the wet & dry conditions by adjusting the Preset in the circuit.
