Description

The GreenBee Project

Appropriate environmental conditions are necessary for optimum plant growth, improved
crop yields, and efficient use of water and other resources. Automating the data acquisition
process of the soil conditions and various climatic parameters that govern plant growth allows
information to be collected at high frequency with less labor requirements. The existing systems
employ PC or SMS-based systems for keeping the user continuously informed of the conditions
inside the greenhouse; but are unaffordable, bulky, difficult to maintain and less accepted by the
technologically unskilled workers.

The objective of this project is to design a simple, easy to install, microcontroller-based
circuit to monitor and record the values of temperature, humidity, soil moisture and sunlight of
the natural environment that are continuously modified and controlled in order optimize them to
achieve maximum plant growth and yield. The controller used is a low power, cost efficient chip
manufactured by ATMEL having 8K bytes of on-chip flash memory. It communicates with the
various sensor modules in real-time in order to control the light, aeration and drainage process
efficiently inside a greenhouse by actuating a cooler, fogger, dripper and lights respectively
according to the necessary condition of the crops. An integrated Liquid crystal display (LCD) is
also used for real time display of data acquired from the various sensors and the status of the
various devices. Also, the use of easily available components reduces the manufacturing and
maintenance costs. The design is quite flexible as the software can be changed any time. It can
thus be tailor-made to the specific requirements of the user.

This makes the proposed system to be an economical, portable and a low maintenance
solution for greenhouse applications, especially in rural areas and for small scale agriculturists.

hello amit sir.....congrats for ur ninties in ur project...

i m quite impressed with the project. So i too hav decided to work on it..but there are not too much discussion in forum on it.
i have some doubt like....

i m not much good on 89s52...can i use another microcontroller by keeping the same programming as u gave us?
do i need another programmer. i have for 89c51?
flash magic and topview simulator dont have this microcontroller in the list while keil evaluation software only provides upto 2k..

plz help regarding me so that i can start work....main problem is 89s52.....dont know much abt dat...

thanks once again 4 this gr8 project

Thank you all very much.

@aryan, harman, Please post doubts in the forum. You can use 89c51 also. Just check what is its ROM size as the code is more than 2K. 89S52 that i have used is same as 89c51, just a few variations which I have not bothered to use. Please check a thread "Sensors" which has the entire discussion of the project.

@amrita if you read the report, you can find I have suggested a number of improvements, but you may have to change the uC for that.

Please note that I have been informed there is an error in the code. I am trying to find the final real working code but am unable to do so. Kindly start this if you can complete the code.
