A RECAP

Project deals with irrigation of farmlands based on soil wetness thus making it more fertile.

Since completely automatic, constant monitoring is not required.

Solar energy is used to generate pollution-free power thus making it completely eco-friendly.

By effective utilization of Atmel based microcontrollers and Solar panels, our objective can be attained.

PROJECT EFFICACY ON A BROADER PROSPECTIVE

65% of India’s Population depend on Farming for their livelihood

Since Solar Energy is used, Independency on power supply & manual labour

Better Yield and Thus reduced Food Inflation

SENSING DESIGN

2 10K resistors come in the voltage divider circuit. The other voltage dividing will happen in the second arm.

So, comparator will give either 0V or 2.5V. This is taken as digital 0 or 1 respectively.

Circuit is designed such that any resistor can be used.

MICROCONTROLLER USED FOR AAIS:

ATMEL’s famous AT89C2051Salient Features of AT89C2051: 2000 Bytes of Programmable Flash Memory 2.7-6V Operating Range 15 Programmable I/O Ports Programmer interface is PC serial

compatible. Accepts Hex Files.

PART1- AAIS ALGORITHM

STEP 1: START AAIS

STEP 2: CHECK VOLTAGE ACROSS SEN1,SEN2,SEN3,SEN4

STEP 3: IF 0V ACROSS ALL THE SENSORS JUMP TO STEP 6

STEP4: SEND VOLTAGE SIGNAL TO EITHER PORT 3.0,3.1,3.2 & 3.3

STEP 5: CLEAR THE LOAD WHICH PULLS P1.6 TO GO LOW, WHICH KEEPS PUMP RUNNING,JUMP TO STEP7

{

STEP 1: 12V SOLAR PANEL INTERFACED TO BATTERY

STEP 2: LEAD ACID BATTERY POWERS THE PUMP

}

STEP 6: SETB TO LOAD,P1.6, ,THAT IS 18TH PIN. IT ENERGIZES THE 12V RELAY COIL

AND STOPS THE PUMP.

STEP 7: GOTO STEP 2

STEP 8: STOP AAIS

PART2- SOLAR DRIVEN PUMP

Solar Panels continuously charge the 12V Lead Acid Battery through a charger.

Charger also helps in stopping reverse currents.

Around 300mA of current from the solar panel was found sufficient enough to charge the battery.

Battery took around 6 hours to charge.
