Airborne particulate matter (PM) is definitely not a solitary pollutant, yet rather is a combination of numerous chemical compounds. It is a mind boggling combination of solids and vapor sprayers made out of little drops of fluid, dry strong parts, and strong centers with fluid coatings. Particles change generally in size, shape and chemical piece, and may contain inorganic ions, metallic mixtures, elemental carbon, natural endlessly compounds from the world’s outside layer. Particles are defined by their diameter for air quality administrative purposes. Those with a diameter of 10 microns or less (PM10) are inhalable into the lungs and can actuate antagonistic wellbeing impacts. Fine particulate matter is defined as particles that are 2.5 microns or less in diameter (PM2.5). In this way, PM2.5 includes a part of PM10.

PM10 and PM2.5 frequently derive from various emissions sources, and furthermore have different chemical compositions. Emissions from ignition of gasoline, oil, diesel fuel or wood produce a large part of the PM2.5 contamination found in outside air, as well as a critical extent of PM10. PM10 likewise incorporates dust from building destinations, landfills and farming, out of control fires and brush/squander consuming, modern sources, wind-blown dust from open terrains, dust and pieces of microbes.

Well the first step to fighting PM2.5 and PM10 pollution is to be able to detect it and monitor it with ease. So we here develop a PM10 and PM2.5 air pollution monitoring system using Arduino Uno. The system makes use of Arduino uno controller along with an OLED Display, Dust Sensor, Matrix Keypad, switches and buttons along with basic electronics component and PCB to develop this system.

The system when started allows user to select one of the two operations:

  • Settings Mode
  • START/Monitor Mode

The settings mode allows user to set some monitoring and alert parameters in the system. The user can first set the upper and lower limits for PM 2.5 particulate monitoring along with the upper and lower limits for PM 10 particulate monitoring.

When user sets all the stings and navigates to the start monitoring, the system starts analyzing sensor data. The controller constantly senses sensor output to get current PM10 and PM2.5 matter data. This data is also shown on the OLED display for monitoring. As soon as the PM2.5 or PM10 level goes beyond the respective set limits the system sounds a buzzer alert and indicator LED to indicate an alert signal.
This is how the system allows user to live monitor PM2.5 and PM10 pollution data as well as sound alert when it is beyond set limits.
