Introduction :

Green house is a laboratory where research is conducted on crop behavior at different, simulated environmental conditions.

Micrologic developed a PC-based system for monitoring, control and data logging of environmental parameters like temperature, humidity, and light intensity without human intervention.

Highlights :
Design, Manufacture, Test and Supply of PC-based Control System to control environmental parameters in a greenhouse.
Control and Data acquisition of various parameters like tempe ....etc

Abstract
According to the environmental parameters monitoring requirements in greenhouse, a wireless
measurement and control system for temperature and humidity is developed. It overcomes the disadvantages
of wired monitoring system, such as complicated wiring, and difficult maintenance. The environmental
parameters in every greenhouse were measured and controlled by microcontroller.
The hardware and software of the monitoring system are discussed in detail. The experimental results show
that the developed monit ....etc

MONITOR AND CONTROL OF GREENHOUSE ENVIRONMENT


Appropriate environmental conditions are necessary for optimum plant growth, improved crop yields, and efficient use of water and other resources. Automation of 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 labour requirements. The existing systems employ PC or SMS-based systems for keeping the user continuously informed of the conditions inside the greenhou ....etc

ABSTRACT
Bio-technologies have evolved into viable treatment technologies not only for odorouscompounds, but more complicated mixed airstreams that include volatile organiccompounds (VOCs). Digestion of compounds such as benzene, toluene, ethylbenzeneand xylene (BTEX) have been of particular interest in petroleum processes and clean-upprojects as an alternative treatment to incineration technologies.A bio-oxidation treatment process, bioremediation, has been successfully implemented ina variety of projects and conditions. Tak ....etc

The Greenhouse Effect on Earth



Earth’s atmosphere is slightly warmer than what it should be due to direct solar heating because of a mild case of greenhouse effect…

The ground is heated by visible and (some) infrared light from the Sun.

The heated surface emits infrared light.

The majority of Earth’s atmosphere (N2 and O2) are not good greenhouse gas.

The small amount of greenhouse gases (H2O, CO2) traps (absorb and re-emit) the infrared r ....etc

Abstract.
Wireless sensor network is a new research field. It can be used in some special situation for signal collection, processing and transmitting. Zigbee is a new Wireless sensor network technology characteristic of less distance and low speed. It is a new wireless network protocol stack of IEEE 802.15.4. Lately traditional system to collects parameters for Greenhouse is widely used in agriculture. The ....etc
