Voice Authenticated Smart Irrigation Using Gsm

ABSTRACT:

A smart and novel way to develop the current farming system has been proposed in this paper. Proper irrigation of crops is one of the most important aspects to produce a perfect yield of crops and a good quality product. Untimely and underdeveloped crops are unhealthy and cannot be marketed. Also, unnecessary irrigation and improper farming significantly wastewater resources. This paper aims to produce a methodical way of irrigation in which the farmer can practice irrigation from any remote location at any particular time.

The farmer can easily identify the status of the motor through voice authentication in his/her regional language. This helps the farmer be aware of the irrigation status. This data will be displayed on a screen with the help of General Packet Radio Service (GPRS), thus giving the farmer easy access from any place. The main goal here is to rekindle the interest of youngsters to consider agriculture seriously in the future and to make it easier for farmers to practice farming in a techno-friendly manner.

Keywords: any remote location, the status of the motor, voice authentication, regional language.

I. INTRODUCTION:

Agriculture is the process of producing food, feed, fiber, and many other desired products by the cultivation of certain plants. The whole world depends on agriculture even though they do not realize it. It is the single largest livelihood provider in India, more so in the rural areas. It contributes a very significant percentage to the Gross Domestic Product (GDP) of India.

Sustainable agriculture, in terms of food security, rural employment, and environmentally sustainable technologies such as soil conservation, sustainable natural resource management, and biodiversity protection, is essential for holistic rural development.

Today’s youngsters however do not understand the importance of agriculture to the economy and the food industry and mock it for being backward and just a countryside business. Slowly more and more farmers are giving up their lands and profession as they feel that they have fallen behind in their economic status.

There are currently four systems in irrigation of agriculture, they are:

1. Surface irrigation
2. Drip irrigation
3. Hose irrigation
4. Flood irrigation

All these types of irrigation happen with no timer, no status recognition, and at random which results in a huge loss of water and water resources. Sometimes, it also leads to crops being overwatered which might result in the withering of crops. This happens due to the farmer not knowing the status of his motor. This project helps the farmer to know the status of his motor and to carefully regulate it. The main area concentrated in this paper is irrigation which will help farmers to regulate and switch on/off their motors from a remote location without requiring actual physical presence.

This research aims at developing a system that will encothaturage future youngsters to take up agriculture as a profession of engineers and not just another old man’s business. It encourages this in a modern and sophisticated manner instead of the traditional methods which have been in practice for centuries.

The system provides two modes- one targeted towards literate farmers, where they can receive an SMS on the status of the motor, and the other towards illiterate farmers, who will receive a voice authentication in their regional language regarding the motor status. To enhance the support given to the farmers, the data will also be displayed on a screen with the help of General Packet Radio Service (GPRS)

The security feature of this project is one of its highlights as only the mobile number which has been pre-registered to the SIM can be used. No other mobile number can switch on/off the motor thus ensuring total security and reliability.

Ultimately the proposed system will make irrigation easier for farmers by giving them access to technology interface betweentohelpsbetween Phelps that helpsthat them effectively control the electric motor.

II. SYSTEM DESIGN:

A. DESIGN ABSTRACT:

The microcontroller used in this design is an Arduino ATmega 2560, which is used to give the status of the electric motor (ON or OFF). A 2-channel Relay module gives a regular alarm which enables the Arduino to monitor the status of the motor regularly. This status is displayed on an LCD which is connected to the Arduino via an LCD Interface. The Arduino communicates the status to a SIM (900A) via a voice module (aPR33A3). These are the basic components involved in the system.

B. COMPONENTS INVOLVED:

The main processor/controller used here is the Arduino ATmega 2560 manufactured by Arduino. The ATmega2560 is a low-power CMOS 8-bit microcontroller based on the AVR-enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega2560 allows the system designer to optimize the power consumption versus speed ratio. It has 15 analog input ports and 54 digital input ports. It also has 4 USART ports. It operates in the range of 7-12V/1A. It is used because it was found to have the most optimal interfacing techniques concerning the other components used.

The device is manufactured using the Atmel high-density non-volatile memory technology.  By combining an 8-bit RISC CPU with In-System Self-Programmable Flash on a monolithic chip, the Atmel ATmega2560 is a powerful microcontroller that provides a highly flexible and cost-effective solution to many embedded control applications. This device can be programmed using the C language or the built-in AVR systems language.

The SIM900A is an ultra-compact and reliable wireless module. It is a sim card module. The SIM900A is a complete Dual-band GSM/GPRS solution that can be embedded in customer applications. It can be used for the DTMF feature which applies to the project. This DTMF feature is very robust in the 900A model when compared to other older models such as the 800 and 700. This sim is easily interfaced with the Arduino processor using a 3V and 5V transformer.

The aPR33A3 is the voice module system used in this project. It is manufactured by APLUS integrated circuits. It can do both playback and record audio/voice. It is an 8-channel system. It is a Single Chip, High-Quality Audio/Voice Recording & Playback Solution system used for Arduino interfacing. It has a 16-bit digital audio processor. Its operating range is 3-6.5V DC. The resolution is up to 16 bits. This helps in producing perfect clarity in the regional language. The desired regional language is pre-recorded into this voice module using a playback channel and then sent to the speaker through the string function when called.

The Arduino Relay module allows a wide range of microcontrollers such as Arduino, AVR, PIC, and ARM with digital outputs to control larger loads and devices like AC or DC Motors, electromagnets, solenoids, and incandescent light bulbs. This module is designed to be integrated with 2 relays that it is capable of controlling 2 relays. This system switches the ON/OFF status of the motor.

Transistor-transistor logic (TTL) is a digital logic design in which bipolar transistors act on direct-current pulses. Many TTL logic gates are typically fabricated onto a single integrated circuit (IC). Standard TTL circuits operate with a 5-volt power supply. A TTL input signal is defined as ‘low’ when between 0 V and 0.8 V concerning the ground terminal, and ‘high’ when between 2 V and 5V. It is used here to mainly interface the Arduino with the SIM900A.

C. INTERFACE:

The Arduino is individually interfaced with the LCD, sim, Voice module, and the 2-channel relay module as an input to the output interface. All these interfaces are then combined and then projected as a single algorithm. The only other interface here is that the voice module is also interfaced with the sim to provide more clarity to the output. The regional language is voice recorded as input. This language is then interfaced with the system with the use of string function in the interface algorithm. The if and if/else function is used to call the related voice string from the main memory for the required function. There is also a pas code service in which the user has to enter the passcode to start controlling the motor. Failure to enter the passcode will deny access to the system. This feature is one of the main highlights of this system. This allows only the legitimate user to control the system and no outsider can access the system through fraudulent means.

IV. REAL-TIME TESTS:

The components were all interfaced and a test run was done.

This resulted in the motor application running successfully with the help of the DTMF-enabled mobile phone. There was also voice acknowledgment in the desired regional language of the farmer from the voice module over the status of the motor. This was a successful test.

In the other operational mode, the motor was switched on and ran successfully and the status of the motor was conveyed to the farmer over the SMS through his mobile.

The system was also tested over a single-phase energy system since most farmers do not receive the three-phase power system and this module was also implemented successfully

All these tests were run with the help of a normal DC motor. Since the working of the DC motor and the water pump are the same, it is expected to be implemented successfully.

V. CONCLUSION:

From the real-time tests and from actually running the system, it can concur that the system is a successful development from the old irrigation models. It can be successfully used in the real-time world. The cost of the system and its installation as mentioned above is also very less and is a practical usage applicant. The motor usage status of the system is successfully provided and shown as output. This system has successfully provided regional language (Tamil) authentication for the status of the motor with the usage of a mobile number. This information is also displayed on a web-based application. Further developments in this system would be to incorporate the use of a mobile app to control the motor status. This app would be a cloud-based app and could also be made available in the regional language for the farmer to easily use it.
