## Electric Motor driven Water Pump activated by Temperature Sensor

FIND A SOLUTION  AT  Academic Writers Bay

In recent times the farmers have been using irrigation technique through manual control in which the farmer irrigate the land at regular intervals by turning the water pump on/off when required. This process sometimes consumes more water and sometimes the water supply land is delayed due to which the crops dry out. It is an electromechanical system. There is advance mechanical water pump which will use to irrigate the crops in farms. The dc electric motor (permanent magnet dc motor or PMDC) will be used to drive this pump. The motor is controlled by the controller which is connected to the battery and the temperature sensor which give a signal to the controller when the surrounding temperature will increase or decrease.
The temperature is set to (35OC) in the controller whenever it will increase or decrease from the set temperature it will automatically turn on/off the motor with the help of controller and battery which is connected with it. After that with the help of motor water pump which is connected to the motor will send water to the farms. It will useful for those crops which need constant water and should soak during the growth which will reduce the dry out problems of crops.

PROBLEMS
Two of the most widely recognized issues with cultivating water system frameworks need to do with water system booking. Water system booking is just noting the inquiries of “When do I water?” and “To what extent do I water?”. Beginning a water system cycle too soon as well as running a water system cycle too long is considered overwatering. At any rate, this training squanders water and cash. Be that as it may, over watering can cause edit harm if done on a delayed premise. In like manner, beginning a water system cycle past the point of no return or not running the framework for a sufficiently long timeframe is considered under watering and can cause decreased yields and poor harvest quality which can influence cost.
There is also one most common problem which is faced by most of the farmers is field situated miles away from their homes. They have to travel daily base at several time to start or stop the irrigation water pump which is too important for the crops which consume more time. some time due to over irrigation and under irrigation crops are damaged by which farmer face big loss as shown in picture 1.1.
Some farmers have more land and they have more need of manpower because of manual turning on/off for water pump which will take more time and become costly because of labor. . Problems sometimes without automatic irrigation system picture of the farm.
AIM/OBJECTIVES
A model of controlling irrigation facilities to help millions of people. In many countries, agriculture plays an important role in shaping up the economy and the climate conditions are anisotropic. the main purpose of this project is to save crops from dry out and the time which is also important in human life.
The model uses temperature sensor technology with the controller to make smart switching devices. It is the basic automatic switching mechanism of motor water pump using the sensor from surrounding temperature. This system can be operated at night and water which loss from evaporation is thus minimized. The most significant advantage is that water is supplied only when the temperature is increased and the plant has need of water. It works according to temperature and keeps soil soaked whenever it going to dry because of temperature. It will also reduce the consumption of water and save the lot of water which will more beneficial for the dry areas of the world.
There is also one more biggest advantage of this project is it will also help to increase the production of the crops and save crops from dry out which is also good for the farmers and those countries which totally depend on the farming. It is the highly sensitive product with the low cost by which poor farmers can also buy this in their budget. With the help of automatic irrigation system picture of a farm.

Question descriptiona.A typical sensor node has a transmit duty cycle of 4% (see Activity 6 ) and draws a current of 1.95 mA while it is in the active part of the duty cycle, and negligible current while in the inactive part of the duty cycle. On average, the node sends 390 bits of data per transmission and each transmission takes 35.0 ms.i.How long does each node transmit for in every hour? Express your answer in seconds.ii.If each sensor node has a battery with a capacity of 2610 mAh, how long a transmission is this battery capable of powering before it must be recharged or replaced? Express your answer in seconds in scientific notation.iii.At what data rate is data transferred in each transmission? Express your answer in kbps.Give all your answers to 3 significant figures.Activity 6Calculate the duty cycle of a device that typically connects to a network and transmits for 20 ms in every 0.5 s. You may wish to use a calculator for this activity.Answer20 ms = 20 × 10−3 s = 0.02 sSo the duty cycle is (0.02/0.5) × 100% = 4%This means that the device is operational for only 4% of the time.

## Building a Wireless Sensor Network

FIND A SOLUTION  AT  Academic Writers Bay

1.0 Introduction
In the previous era, the technology application mostly using wire but now a wireless device has become common place. The definition of wireless sensor network is an application that having no wires connection on that devices. In addition, to make the system easy to monitor from a distant location, the RF 433MHz module was used. So, this project gave rise to the idea for studying details about the RF 433MHz module performance for WSN application.
1.1 Project Background
Nowadays, using the wireless sensor network (WSN) technology to monitor the environment helps someone to solve the problems of deployment difficulty, high cost, and realized unmanned monitoring which is mostly used in factory, buildings, laboratory and house. This project is to study the range and performance of the RF 433MHz module for WSN application. RF 433MHz module are popular used in remote control system. This range also available to use in this area. There are two types of the RF module which is transmitter and receiver. From research, using RF 433MHz module, the data can get more accurately without any data losses with the range that given than compared to other transmission for wireless sensor network.
The range that can reach by this RF module is different between outside and inside area. For inside area, it can work for 50 meters through multiple walls with an antenna, while for the outside area, it will be able for hundreds of meters. Besides that, a microcontroller such as Arduino also used in this project. Arduino that available for this project is Arduino PRO which is it has 3.3V port that will be easier to connect directly to the types of RF 433MHz module that used in this project.
This project also will be studied the analysis of the data transmission by giving a few of distance between the transmitter and receiver of the RF 433MHz modules when located in the obstacles or line of sight area. Then, the data that are received will be displayed on the computer whether there are data losses or not.
1.2 Problem Statement
The problem that becoming as issues right now is there is a lot of ways to send data but the problem is about the range, cost, and data losses. So, for this situation, study the performance of RF 433MHz can overcome the problem for the WSN application.
1.3 Objectives
The objectives of this project are to understand the range and performance of RF 433MHz module. Moreover, exploration about the transmitting and receiving the data by using the RF 433MHz module.
1.4 Work Scope
The main work scope of this project is to make sure this project will achieve the objectives.
The main focus of this project:-
i. To study and understanding the range of RF 433MHz module.
ii. To transfer data by using RF 433MHz module.
1.5 Methodology
In this project, there are three main parts. For the first part, it will be focused on the conducting the literature review and do some research more detail about the RF 433MHz module. Meanwhile, for the second part, after the software development process, the hardware development process will take over and include the testing of the project. Last part, when the hardware and software complete their part, it will be followed by testing the performance and the operation of the project to make an analysis.
1.6 Report Structure
