Abstract-For providing a high socio-economic level of the population of a country high technical equipment of the enterprises producing and processing agricultural products has quite an essential value, especially in the newly developing countries such as Armenia.The introduction of modern leading technologies into the farms and agricultural enterprises will support the fast growth of production that will in its turn result in the increase of the social level of the population and decrease of the poverty.The aim of this paper is the development and creation of an experimental sample of "Ecology-Microclimate" agricultural controlling-measuring automatic electronic system, which is intended for distant measuring and regulating of the air temperature and relative humidity of the closed spaces or areas of the enterprises (farms) as well as for controlling the concentration of polluting/harmful gases (methane and ammonia).The introduction of the "Ecology-Microclimate" system in the poultry factories and other farms and greenhouse enterprises as well as grain product stores will undoubtedly lead to the increase of the production and safe long-term storage.

I. INTRODUCTION
The contents of each section may be provided to understand easily about the paper.The current state of agriculture in our country and the level of agricultural production in particular, for scientific-technical workers face serious problems in the development of new technologies, the creation and implementation of the relevant fields.These technologies were developed based on the achievements of the modern Micro and Optoelectronics course will provide a high level of agricultural productivity.
Modern instrumentation and automatic electronic systems is extremely important especially in enterprises such as poultry and livestock farms, fruit and vegetables, dairy and meat refrigeration farms, greenhouse and incubation farms, grain warehouses, etc.
A high level of gas-aerosol pollution in the environment more importance to the creation of new devices and systems and ecological investment, especially in agriculture.There is no need to mention the huge role that the provision and regulation of climatic conditions (temperature, humidity, etc.), as well as the monitoring of concentrations of air polluting gases in above mentioned agricultural facilities, agricultural productivity and ensure a high level of safety protection.

Microclimate", which provides high production of agricultural products, processing and long-term conservation of a number of units of measurement, regulation of air temperature and humidity, as well as concentrations control of polluting gases (methane and ammonia) for ensuring ecological safety climate conditions.Installation of a number of performers (ventilators, conveyors, work heaters, etc.) mechanisms lead to "Ecology-Microclimate" system combined with a personal computer."Ecology-Microclimate" system relevant enterprises can provide a dramatic increase in productivity, which in turn will help improve the socio-economic level of the population.

II. SHORT DESCRIPTION OF EQUIPMENT
"Ecology-Microclimate" system is expected to be closed in accordance with the agricultural areas of air temperature and relative humidity measurement and regulation facilities, as well as for control of volumetric concentrations of CH4 and NH3 gases in order to provide an ecologically safe environment.Automatic measurements, as well as a number of actuators (air conditioners, heaters, conveyers work, etc.) in order to operate the device, combined with the computer."Ecology-Microclimate" feedback system helps to supervise the enforcement mechanisms work, providing the necessary facilities for safe environmental conditions and climate.
"Ecology-Microclimate" equipment consists of two main units: Electronic Control Block (ECB) and block sensitive elements (BSE).Fig. 1 illustrates the device functional scheme.BSE will contain a heat-sensitive element (Si termodiod) humidity sensitive element and TGS-826, TGS-842 gas detectors.ZEB-in must be installed on the volume or rooms where it is necessary to measure and regulate climatical and ecological parameters and connected to the electronic control unit and computer by cables, cables length can be up to 100 meters.EKB and the operating system can be deployed in operator comfort zone.The content of the technical component of the paper consists of the following that it has (see Fig. 1) ambient air temperature (1), relative humidity (2), ammonia (3), methane (4) Gas detectors (2, 3), amplifiers (5) analogdigital Modifier (6), microcontroller sensor node (7), managing microcontroller receiver system (8), all the nodes power supplier source (9), sensors, limit data memory device (10), decoder (11) , measurement results support the LCD indicators (12), switchboard (13),connect and disconnect signals switches (14), the coupling with computer interface (15), and computer (16) receiving instructions and data sending.
The principle of operation of the device is the following: temperature, humidity, ammonia and methane gases from sensors signals are amplified by amplifiers, analog-digital and digitized modifier.from microcontroller consecutively code sensor unit forms a periodic signal that a pair of wire sequence of digital values of the sensor output to the receiver managing microcontroller that performs the following actions: Power Unit (9) supply current at a low voltage of all the nodes, data setting unit memory device (10) are registered by sensors necessary boundary data decoder (11) with the help of digital sensors the current values of detectors are on the digital display (12).Memory device current sensor values exceed pre-registered setting data (or decrease) in cases commutator (13) of the plugs (14) to the separation (or switching) signals.Microcontroller leading receiver (8) implements the interface (15), with the help of a computer (16), for receiving instructions and data sending.
In terms of design the system consists of two units moving to block sensitive sensors (BSE), which contains temperature, humidity, ammonia and methane gas detectors, amplifiers and analog-to-digital converters; and the electronic control unit (ECB) (see Fig. 1), combined with the personal computer.BSE is placed at the corresponding areas and volumes, where it is necessary to measure, control and regulate air, climate and ecological parameters, the cables connected to the ECB, whose length can reach up to 100 meters.ECB can be installed with a computer for operator convenient location.
On the front panel of the ECB pre-installed ambient climate (temperature and humidity) and ecological (volumetric concentrations of methane and ammonia gases) required parameters (permissible) values.Ambient air measured parameters values, allowable values in advance (in the case of deviations) from the limit of measurement errors ECB -output to control signals for the external actuators (e.g.fans, conveyors, heaters, etc.) for the operation and functioning in this object.
Developed by us the "Ecology-microclimate" modern technology provide the range of ambient air relative humidity from 10 to 90%, with measurement and regulation, by 10% -discrete steps, measurement accuracy of ± 1% (on the level of the measured value); measuring and regulating air temperature in region from 100 to minus 400, with discrete interval of 5 0C , by measurement accuracy of ± 0.5%; ambient air methane (CH4), ammonia (NH3) gas density allowable limit from 0.25 to 0.5 of the value of the output signal; the measurement results in automated processing and management of a variety of actuators ensures coupling with the personal computer.III.CONCLUSION Developed automatic electronic system "Ecology-Microclimate" can be widely applied to agricultural processing companies, poultry and livestock farms, greenhouses and incubation farms, fruit and vegetables, meat and grain storage facilities and refrigerators.This new technology will undoubtedly lead to a sharp increase in agricultural productivity to secure long-term conservation of different products.
Agricultural "Ecology-Microclimate" automatic electronic system currently existing analogue differs from the two main news production areas of climate (temperature, humidity) parameters control and regulation in addition to the controlled and regulated by the harmful gases (methane, ammonia) maximum permissible concentrations, and the second "Ecology-microclimate" software manages the system objects (fans of actuators, conveyors, heaters, wet representatives, etc.) work.
