Automating the data acquisitionprocess of the soil conditions and various climatic parameters that govern plant growth allowsinformation to be collected at high frequency with less labor requirements. The existing systemsemploy PC or SMS-based systems for keeping the user continuously informed of the conditionsinside the greenhouse; but are unaffordable, bulky, difficult to maintain and less accepted by thetechnologically unskilled workers.The objective of this project is to design a simple, easy to install, microcontroller-basedcircuit to monitor and record the values of temperature, humidity, soil moisture and sunlight ofthe natural environment that are continuously modified and controlled in order optimize them toachieve maximum plant growth and yield. The controller used is a low power, cost efficient chipmanufactured by ATMEL having 8K bytes of on-chip flash memory. It communicates with thevarious sensor modules in real-time in order to control the light, aeration and drainage processefficiently inside a greenhouse by actuating a cooler, fogger, dripper and lights respectivelyaccording to the necessary condition of the crops. An integrated Liquid crystal display (LCD) isalso used for real time display of data acquired from the various sensors and the status of thevarious devices. Also, the use of easily available components reduces the manufacturing andmaintenance costs. The design is quite flexible as the software can be changed any time. It canthus be tailor-made to the specific requirements of the user.This makes the proposed system to be an economical, portable and a low maintenancesolution for greenhouse applications, especially in rural areas and for small scale agriculturists.[text taken from project synopsis] http://www.8051projects.net/downloads208.html 2008-09-05T10:39:55-07:00 Gioppy PIC Projects Here a nice graphic temperature recorder.FeaturesIt shows 60 samples.

So i spent some time making this project.You will find working of this project same as that of original project. Nothing has been changed as such.Its a simple project with efficient hacking prevention from Brute Force etc. The basic user lock is of 5 Digits and Master Lock is of 10 digits so its not easy for an intruder to break the lock unless you keep the code simple.The input is taken from a 4x3 Keypad (please see the schematic for more information) and Display the user input on a 2x16 LCD. A pin is assigned as output for activating and deactivating the lock. For demonstration i have connected an LED to that pin.User Side working:The user has two options either he/she can use its own 5 digit code or use the default 5 digit code. If user has to do setup his own code, then he has to enter "12345" and press '#'. After this.. controller will ask for 10 Digit master password which is preprogrammed in the controller. Entering master lock, user can enter the new 5 digit code for the lock and press '#' to save it.Using the Keypad:Keypad has 12 keys (4x3) starting from 1,2,3,4,5,6,7,8,9,*,0,# (please see the schematic for layout). Numeric keys are used for entering numbers. '*' is used as the Cancel key and '#' is used as the Enter key.Download File Information:LCD.asm - Project CodeLCD.hex - Final Hex fileDigital Code Lock Schematic - PDF file of orcad schematicIf any problem Please post in the forum http://www.8051projects.net/downloads205.html 2008-09-05T10:39:55-07:00 Shivani, Geetika Gupta, Vibhore Aggarwal, Megha Singh 8051 Projects Introduction:EVM is capable of saving considerable printing stationery and transport of large volumes of electoral material. It is easy to transport, store, and maintain. It completely rules out the chance of invalid votes. Its use results in reduction of polling time, resulting in fewer problems in electoral preparations, law and order, candidates' expenditure, etc. and easy and accurate counting without any mischief at the counting centre. It is also eco friendly.Our EVM consists mainly of two units - (a) Control Unit (CU) and (b) Ballot Unit (BU) with cable for connecting it with Control unit. Both the units consists of one microcontroller (8052) each. The CU consists of one LCD, one hex keypad and a couple of switches, while BU consists of a candidate panel, a votecast panel and a buzzer, etc. This project is based on assembly language programming. The software platform used in this project are Keil uVision3 and SPIPGM37.Important Information:Please Read this carefully as explained to me by authorauthor wrote ...i forgot to mention one thing missing in report n coding as well.actually, in main function of control unit program as soon as controllerenters in it check the value of variable named "status" that resides in EEPROM. If status is 1 then voting start else no voting.if the EEPROM is new or fresh, status will have some garbage valueor 0xFF. which can be a problem on first startup.So a small program is written to clear that status byte.After you finish making the hardware. You have to do the following things:1. Load cufirst.hex file in your controller.2. Run your circuit.3. Wait for 2-3 seconds.4. Load voting.hex which is the real control unit program.5. Run it.Please use forum if you have any problem.www.8051projects.net/forum.html http://www.8051projects.net/downloads204.html 2008-09-05T10:39:55-07:00 GioppY 8051 Projects GioppY wrote ...BASCOM-8051 compiler AT89C2051 Simple counter frequency range 1Hz - 400.000Hz period range 100uS. - 8.000.000uS.N.B.

We use CAN for Monitoring Sensors. Data can be stored in the System and the software is used for backup. We can get reports on hourly, weekly and monthly basis.The Controller Area Network (CAN) bus is a multi-master message broadcast system that is suitable for systems where data contained in short messages are needed to be received at multiple locations simultaneously. Because messages are sent to all the nodes in a system, CAN is especially suited to systems where consistency in the received messages at all the receiving nodes is needed. In this case, all nodes are notified of the rejection, ensuring the data consistency across the network.Messages are sent to all nodes, but their “message identifiers” indicate whether each node should act on the message. However, all nodes participate in indicating whether the message was sent correctly, increasing the reliability of the bus.Designing and development process can be divided in to three Section.more information available in word document format... http://www.8051projects.net/downloads198.html 2008-09-05T10:39:55-07:00 Abbas Proteus Simulation Projects This is a sample project for proteus and including driver program for ds1621 written in c.
