Air pollution is everywhere and the polluted air can be very harmful for human. Based on Air Pollutant Index of Malaysia, the air pollutant included are ozone (O3), carbon monoxide (CO), nitrogen dioxide (NO2), sulphur dioxide (SO2) and suspended particulate matter which less than 10 microns in size or more well known as PM10. Fine particulate matter is one of the key global pollutants affecting human health such as lung cancer, cardiovascular diseases and other related diseases. This portable air monitoring devices are developed in order to help the public monitor their air quality. This device is low-cost in term of device and components also it is easy to use. Generally, this device detects PM when the particles enter the sensor box and …show more content…
Particulate matters are the most dangerous to human health. This is because the sizes of particles are directly linked to potential of health problems as it is within the respirable range. The respirable range is a particle with a diameter of 10 micrometers or smaller that does not exceed more than PM0.1 can easily pass through human respiratory system and deposit there. Therefore, once it is inhaled it can affect the heart and lungs, which lead to serious health effects especially to those who have asthma. Thus, with this air quality monitoring system human can prevent health problems. This portable monitoring system also helps public to monitor their air quality anytime and …show more content…
The device work by filtering the dust into the sensor. The particle from the dust that are generated by the heater resistor pass through its sensing point, the light receptor will receive the scattered light and transform it into pulse signal (known as Low Pulse Occupancy Time, LPO time) which proportional to PM concentration. If the sensor detect PM10, the LED will be ON, buzzer sound for unhealthy level and LCD will display the reading as shown in Table 1. Next, Figure 4, show the comparison of sample data tested along with EVM-7. EVM-7 is a certified device use by KKM that can measure particulate matter and many more. It use 90 deg light scattering photometer to measure the particulate. It was tested in a moving car with the ventilation air is open and accelerate for about 20-30km/hour. The testing take place around campus of UiTM Shah Alam. The data for EVM-7 show a linear increase but for proposed device of DM10 shows an unstable data. This might be happened because of the placement of the proposed device not at a suitable

3. Management a) Syslog: Network infrastructure devices, workstations and applications generate syslog messages that an administrator should be periodically reviewing and resolving. These log messages should be sent to a single location to allow effective review and management. Kiwi Syslog Server collects, organizes and archives syslog messages from the entire network, and can alert an administrator to events through email, text or audible alarms [60]. b) Network Monitoring: Monitoring applications, such as SolarWinds, provide the capability to monitor network performance, manage configuration changes on devices, monitor server health, analyze traffic on the network, monitor user devices and monitor compliance with security policies [61].
Cell Respiration Lab Research Question What is the optimal temperature for germinating pea-seeds where the rate of respiration is the greatest? Background Information Cell Respiration refers to the biochemical process conducted by the cells of an organism that combines glucose and oxygen to produce energy in the form of ATP, along with two by-products, water and carbon dioxide. The equation representing this chemical reaction is shown below. C6H12O6 + 6 O2 6 CO2 + 6 H2O
The Bronx is an incredibly urban and populated area attracting traffic from all over. It is home to waste sites, distribution centers, power plants, and so much more. Though each building gives off a different type of waste, whether it be smog from smokestacks or diesel exhaust from trucks, each of these large sites that exist throughout this small area give off a fine particulate matter known as PM2.5. This matter is essentially what contributes to the difficulty breathing people experience as these tiny particles can become lodged in a person’s lungs over time. Studies have consistently found a strong correlation between PM2.5 and conditions like asthma, lung disease, and heart disease.
To protect from the airborne contaminants of an automation space, there is a NEMA 4/4X enclosure around the device. The operating temperature of the device should stay between 0 and 50 degrees Celsius. The device also has a proper operating humidity which is from 5% to 95%. The are a large amount of ports for the user to connect to.
1. Introduction Air pollutin is a public health concern and it has been since the discovery of fire. Incidents and episodes of air pollution have been recorded throughout the history. Air pollution is divided into two, it is the indoor air pollution and the outdoor air pollution. Indoor air pollution is produced in households or at offices by pollutants such as tobacco smoke, household products or pesticides.

The advancement of automobiles over time has directly affected the advancement of society as a whole. Society relies intensely and increasing on private motorized transport, vehicles are expected to become safer, more luxurious and powerful. These expectation, however do not take into account of the ensuring consequences such as greater emissions of air pollutants and greater exposure of people to hazardous pollution that causes serious health problems. All the evidence points to the magnitude of these adverse effects on health and to the need to identify solutions that both reduce risks to health and meet the requirement for mobility. This creates a major challenge to the governments, public health organizations, environment authorities and most importantly to the design engineers.
b. Credibility: Air is a necessity to be able to live. But today air becomes an element to kill us slowly. Air pollution is a major problem in the world yet it is not given enough attention to. Cities have higher air pollution compared to provinces because of the inevitable huge number of vehicles and heavily congested areas. According to Eva Ocfemia, the assistant director of the DENR-EMB in 2015, the air pollutant concentration of NCR reached 130 micrograms per cubic meters in terms of total suspended particulates (TSP), higher than the previous year and the safe level.
Particulate matter is a complex combination of fine solid particles and liquid droplets comprising various types of dust, smoke, and soot, gaseous and biological contaminants that are suspended in air. The size of these particles ranges from few nanometers to around 100 micrometers. Mainly, coarser particulate matter PM10 with diameter less than equal to10 micrometers and fine particulate matter PM2.5 with diameters less than equal to 2.5 micrometers are significant. Particulate matter in air comes from both natural sources such as wildfires and dust storms and anthropogenic sources like power and industrial plants, fossil fuel burning, combustion of wood and other biomass fuels and automobiles. In Urban areas, vehicular traffic is one of the major sources of particulate matter pollution.
At that time, the sink node uses the IP cameras positioned in the sensing area to record the events and display the current situations. When events are detected by sensors, they start to collect data for a specific period. Fig. 1 shows the proposed system which consists of two parts; sensor side and sink

There are many problems that threatens society and one problem in particular, air pollution is a problem that threatens everyone. Air pollution is the contamination of air with pollutants that are harmful to humans, animals, and the environment. It began to be a problem when humans discovered the uses of fire and then the amount of air pollution exponentially grew after the industrial revolution, and is still a problem even today. The largest causes of air pollution are from human activities such as burning of fossil fuels and gas emissions from manufacturing plants. There are ways that ordinary people can help contribute to prevent air pollution and or else face the dangerous consequences of polluted air.
Rinkesh also mentioned that another cause that can be
