GSM Based Automatic Irrigation System Using 8051 Microcontroller.
Hi Friends, I’m back with a new interesting and useful electronic project with 8051 microcontroller by which you not only you but also the people who are not aware of technology will get the benefits of this system. I am talking about “GSM Based Automatic Irrigation System Using 8051 Microcontroller” that is based on the microcontroller unit. This electronic project provides a facility of controlling the electrical equipments with the help of GSM modem. So I think you have understood that I talked about GSM modem, then the project is capable to control the electrical equipment from any distance in the world.
Actually this project is for our farmers. They work hard and hard not only everyday but also every night in the field. Because in the day they do their field work and in the night our farmers have to irrigate the field land at some intervals.So to wake up in the night from a sleep and then go to field and irrigate the land is to typical for a farmer. There are many disadvantage of this irrigation system that if a farmer started the irrigation system in the night and he forgot to switch off the irrigation system again. In this condition the a lot of water goes to wastage and the crops may get harm or sometimes he forget to switch on the irrigation system then again the crops get dried due to lack of water.This depends on the type of crops. Lighter weight fruits always follow slight water deficiency.
So to rectify this problem I have brought this is electronic project (GSM Based Automatic Irrigation System Using 8051 Microcontroller). The system works on sms feature of the mobile phone. No hard work need to be done by the farmer.He has to send a sms to the irrigation system to switched on as well as off the irrigation system. The irrigation system switching status will be received to the farmer in his mobile as a sms.The return sms will be automatically sent by the irrigation system.This project works on two mode. It depends on the farmer that what he choose to control the irrigation system.
Mode1: In Mode 1, farmer can send the fix time interval in the sms to switch on or off the irrigation system and
Mode2: In Mode 2, farmer can directly send the command to switch on or off the irrigation system whenever he needs.
There is a water level indicatior in the system that gives a signal to the microcontroller that the water is supplied to irrigate the land or not.On the basis of this water status signal the microcontroller devices automatically switches on the irrigation system. The project runs with the help of battery power, So this continuously monitor the power failure. If a power failure occures then after getting power again, the irrigation system switches on again. In the block diagram you are seeing a DC motor that is our irrigation system. A GSM modem is used at the field end microcontroller system to send or receive the messages from the farmer’s mobile phone. Mobile phone is a self gsm modem so there is not need to any additional gsm modem to send or receive the messages from home.The water level indicator circuit send the status of water that the required water is supplied to land or not. A real time clock is also used in the system, by the help of which, the microcontroller knows that when it has to switch on or off the irrigation system using regular interval sent by the farmer in the sms. A blog diagram of is shown below:
A Block Diagram of GSM Based Automatic Irrigation System Using 8051 Microcontroller.
A short description of the block diagram :
The GSM modem is serially connected to the Microcontroller unit. 8051 Microcontroller is the central controller unit of the system. Real Time Clock (RTC) is seprately connected to the micrcontroller to tell it only the time interval. A water level indicator is also an important part of the system that is responsible to switch on or off the irrigation system. A motor driver is an electronic circuit that receives signal from the microcontroller to drive the DC Motor. DC Motor uses its seprate DC Power supply.This is switched on of off by the help of Relay device used in Motor Driver Circuit.
