ABSTRACT: The level of pollution has increased with times by lot of factors like the increase in population, increased vehicle use, industrialization and urbanization which results in harmful effects on human wellbeing by directly affecting health of population exposed to it. In order to monitor quality of air, a Wireless sensor network (WSN) based new framework is proposed which is based on data acquisition and transmission. The parameters of the environment to be monitored are chosen as temperature, humidity, volume of CO, volume of CO2, detection of leakage of any gas - smoke, alcohol, LPG. The values of these parameters are transmitted by using Zigbee Pro (S-2) to a base stationwhere they are being monitored. The value of temperature and humidity are transmitted over Bluetooth also so that every person in the range of the system can check it over their smart phones and laptops as these parameters hold importance to everyone. CO, a dangerous parameter is monitored with an extra precaution. A text message is sent to the base station through GSM module whenever its volume exceeds a particular safe limit intended for a particular application.

Maritime weather buoy is a system consisting of several sensors, data management and data processing so that it can be sent wirelessly to the work station on land. On a ground station there is a system that has a predictor system, acquisition system, monitoring system and distribution system. The acquisition system is a system that serves to retrieve, collect, display and process to get the desired data. The data will be processed to produce predictive information and weather forecasts. This data is also then used for transportation and shipping.
Monitoring environmental parameters are important in various applications. In earlier period, the system of weathermonitoring are generally need a human intervention that sometimes resulted in parallax error and durability. Therefore, this demand a development of a microcontrollerbased embed system for weathermonitoring that monitor and provide data to be examined. For example in agriculture section, it is believe that the change of climate can cause extreme weather events. For example, the events include heat waves, droughts, strong winds, and heavy rains. Droughts are very damaging to the plants because for the long-term, plants will do not have enough water to survive. Besides, it also effects the poverty in the world. Heat waves can give to crops an impact of extreme heat, which can limit the production of the plants. The winds that extremely strong that also can be called as "sandblasting" can cause a severe damages to the plant. Heavy rains that cause flooding can also be damaging to crops and soil structure because most of plants cannot survive in soaked conditions that occurs for a long time because the roots need to breathe. In addition, rain combo with the strong winds can knock down large trees, and ruin the houses. Besides, for the current situation right now that temperature and humidity that is so high like in Malaysia can cause discomfort to the community. Besides, the weather also can changes unexpectedly that becomes a threat for the people safety and comfort. For a person that always face this challenges need to know the changes of environment conditions around instantly so that they can prepare for the worst.
A proof-of-concept for an embedded system-based, multi-signal patient monitoring system oriented for the out-patient consumer market has been established. The patient monitoring device has been developed using an embedded system platform and a collection of biosensors and discrete electronics. Three medical parameters have been selected as part of an application that targets patients suffering from specific deficiencies such as diabetes and cardiovascular diseases. These parameters are blood glucose concentration, heart rate, and blood oxygen level. A custom software application has been built to aid physicians in monitoring and diagnosing their patients’ cases. The device’s design and the software application provide major advantages over existing medical monitoring systems in the device’s prototyping surface area and the overall system’s development time which did not exceed 6 months. This functionality is provided with a cost-effective design due to the use of an all- purpose RISC-basedmicrocontroller as opposed to a proprietary hardware platform. The overall system has been tested with the help of volunteers and the monitored medical parameter readings have been checked against results from existing commercial products. A design process for personal medical devices  has been adopted in addition to a software development process for the development of an integrated solution that aims to serve out-patients, physicians, and OEMs of medical equipment. The proposed design will soon be further enhanced with a wireless communication capability using the public GSM network.
The test subject should wear the body posture sensor on his upper body and the respiratory airflow is collected using a nasal cannula or a facemask connecting with a tube where thermal flow sensor is installed. The oximeter is a clip worn on the fingertip of the subject. The outputs of the sensors are transmitted wirelessly via ZigBee to a PC or cell phone on which the data are processed , respiratory flow waveform, tri axial acceleration and blood oxygen saturation are displayed and the respiratory parameters and body posture are figured out. The PC or cell phone can also transmit the signals to the remote monitoring center or physicians through the internet,
In such environment when some event occurs the alarm or LED alerts automatically. The effects due to the environmental changes on animals, plants and human beings can be monitored and controlled by smart environmental monitoring system. By using embedded intelligence into the environment makes the environment interactive with other objectives, this is one of the application that smart environment targets.

PIC is used in wide range of applications such as commercial, industrial and automotive applications. It is important that the device is tested prior to wiring in the application circuit. PIC microcontroller 18F6520 is tested for its precision using a standalone system. The main controller used is an FPGA onto which the communication protocols are implemented. FPGA device could be used for the communication between test station and a peripheral device that has any one of the communication protocol implemented on the controller. It also acts as a temporary storage of data. The graphical user interface indicates whether the PIC has passed or failed to meet the need.
The Arctic Station is located on the south coast of the Disko Island in central west Greenland. It is thus facing the Disko Bay and is characterized by an arctic, marine climate. There are 3 building comprising guest facilities, staff accomodation, laboratory and library that are located in a nature sanctuary, approximately 1 km west of a small town, Qeqertarsuaq (formerly Godhavn), with ca. 1100 inhabitants. Within the town community is located all necessary service facilities, incl. several shops, bank, postoffice, church and a hospital.
The MAC management service, if the device is a coordinator, manages the network beacons. It is also responsible for PAN association and disassociation, frame validation, and acknowledgment providing “a reliable link between two peer MAC entities.Use the CSMA/CA for channel access and handles and maintains the GTS mechanism to device security. The IEEE 802.15.4 standard defines four different frame types: the beacon, data, acknowledgment, and MAC command frame. All frame types are based on the general MAC frame format. The frame control field describes and specifies the above different frame types.
direct ‘‘data pipe’’ is created to a dedicated IP number associated with the predefined number. Data are routed via an Iridium gateway onto the Internet to the dedicated IP address, linked to the data server in the United Kingdom. Multiple connections to the data server are handled simultaneously. However, each AWS is al- lotted a specific 5-min window every hour to transmit its data. The satellite modem is only powered during this 5-min window. This was implemented to ensure that the modem would not be left powered on indefinitely due to a communications failure, thus leading to a drained battery. In addition, the server could not be overloaded with connections. No quality of service or transmission control is provided by RUDICS. Hence, a specific ‘‘handshaking’’ protocol was developed to maintain ro- bust communication between the remote station and the data server, with minimum bandwidth overhead. The pro- tocol uses a cyclic redundancy check (CRC)-16 checksum calculated over a 222-byte page of data to ensure data integrity. The decision processes required by the remote AWS and the server are shown in Fig. 4. It was found that the Iridium network carried out routine maintenance on a monthly basis, leading to an increase in loss of signal. The handshaking process was therefore necessary to maintain data integrity during such occasions.
Abstract- This paper presents the design and simulation of a wireless patient intelligent health monitoring system with GSM alert Technology. In the hospitals where patient’s body temperature needs to be constantly monitored, this is usually done by a doctor or other paramedical staff by constantly observing the temperature, pulse rate and maintaining a record of these parameters. This is a very tedious method and can really be stressful, especially in overcrowded hospitals. The primary function of this system is to monitor the temperature and pulse rate of a patient’s body, and send the information wirelessly to the doctor’s office on the LCD display unit. In this proposed system, a transmitting unit continuously reads patient’s body temperature and heart rate through digital sensors, displays them on the transmitter LCD. At the receiving end, a receiver is used to receive the data, decode it and feed them to another microcontroller which then displays it on the doctor’s LCD screen. The receiver unit is kept in the doctor’s chamber to continuously display the patient’s body temperature and heart rate wirelessly. An alarm is also activated at the receiver end where the doctor will be, and is activated when the patient’s temperature or heart rate goes below or above the normal human threshold value, which are 37°C and 70 beats per minute. An SMS will be sent to the doctor, just in case he or she is outside the vicinity and to serve as an avenue for constant update. The proposed system was simulated using Proteus software and programs written in Embedded C language. The result obtained shows an efficient method of relating information to the doctor on duty for urgent attention to patients.

Insert three LR6 (AA size) batteries into the Base Station/Console. The console will illuminate for a few seconds with all the display segments illuminated for checking. After this the Base Station will make an initial measurement and start to register the transmitter (the Outdoor Reception Signal icon will be turned on). Do not touch the Base Station before the outdoor data is received or the outdoor sensor learning mode will be terminated. When the outdoor transmitter has been registered the Base Station will automatically switch to the normal display mode from which all further settings can be adjusted by the user.
ABSTRACT: This Paper represents the need of Greenhouse and how much effective they can be in good yield of crops. As plant grows, they need certain environmental parameters for its proper growth like humidity, temperature, light. Also, Automated Greenhouse Monitoring ignores the need of human operators to take care of the plants. To monitor the Greenhouse parameters like humidity, temperature, soil moisture and light properly, a control system is needed. This control system is comprised of greenhouse data acquisition PIC Microcontroller along with temperature, humidity and light and pH sensor. For monitoring and storing the values of these environmental parameters PIC18F452 based circuit is used. Based on the values stored, the above system will compare the stored values with threshold values set for particular plant and control the actions of cooler, heater, and water pump. Greenhouse monitoring and control software can collect, display and record the collected data i.e., values of various parameters, also can control greenhouse environment. In addition to this the system also consists of solar inverter for backup. For displaying the stored values, we have used GLCD. This system is very useful for proper cultivation and maximum yield of crops. KEYWORDS: PIC Microcontroller, Environmental parameters, Control system, Threshold values, GLCD.
