An Update on the Air Monitoring Kit


Vaishali is an intern with Gasp through the UAB Academic Small Business Alliance program.

With the help of our lovely technical advisor, Jon Self, we have built our first prototype of the Air monitor! The monitor will test humidity, temperature, air particulate matter, and sound levels through the phone.

(All of the steps are in a PowerPoint. I’ve included some of the slides at the end of this post.)

“Never doubt that a small group of thoughtful, committed citizens can change the world; indeed, it is the only thing that ever has.”


First we needed to solder the Arduino and powerboost shield then we started connecting each part through wires on the breadboard. Below there is a picture of the prototype. Now you may be wondering how we get to see the information collected by the machine. The air particle sensor displays data to an Android device and runs on a battery so it is very convenient and easy to make!

The problem with our first prototype is the original particle sensor did not pick up PM2.5. So we bought a new particle sensor and we are waiting for the new part to come in. We know that the original sensor was incorrect because we compared the data to Dylos, another air particle sensor and there was a vast difference. Comparing the same time and place, the Dylos PM2.5 value was 1000 and our prototype was 6000.

We are also working on 3D printing a case to hold the air monitor parts and look stylish encasing the equipment. Hopefully this new sensor will work correctly and we can start spreading this project to schools for children to make their own!

Air Monitor Construction Status Update

Air Monitor Construction Status Update

At Gasp my project is to build an air monitor meaning this device needs to measure temperature, nitrogen, oxygen, carbon monoxide, ambient particulate, and humidity levels.

Purpose: Currently, there is a small of amount of data on the particulate matter. There only 7 in Jefferson County that measure fine particulate matter (PM2.5). PM2.5 is an air pollutant and when its levels are high the tiny particles reduce the visibility of the air making the air appear hazy. The higher the PM levels, the worse it is for the lungs so it is important for everyone to know the air quality for their own health and create a safe environment for the next generation.

Future goals: With a successful device, the best way to give back to society is to share our hard work by teaching others how to make their own air monitor. My vision is to create a video with step by step instructions and placing the code on a public platform. A materials kit can be ordered from Gasp and the office would ship the kit to a customer with the link to the instructions and the code. We would like to go to high schools and have a session in class for each student to build his or her own device that they can take home and place it outside.

Current status: We are waiting for the Arduino to ship into the office. The Arduino connects the electronic device to the computer and we use it as a coding software. The Arduino lets us code what we want the machine to do. Our wonderful technical adviser John is working on completing the code. Here’s a picture of all the current parts!
