Popular air quality monitors like Purple Air, Air Gradient, IKEA etc. use sensors primarily from Plantower or Sensirion. These sensors already measure, calculate and report the sensing elements like PM2.5, PM10, VOC, temperature. etc. on their UART port. The air quality monitors read these values off the UART port and display it on a fancy screen or send it to cloud. So, in essence, they are acting like dumb terminals. Their firmware is just read values and display values or send values to cloud. Also, some of them are presented as lifestyle devices, so generally are priced higher.

Also, these sensors cannot accurately measure particulate matter of sizes greater than about 6um, so only PM2.5 is reliable. Mold, Pollen etc have higher dimensions than these. Measuring higher particle sizes may require a different approach.

Pleased to announce that crowdfunding for my design hardware is live now and closing soon!

It is budget friendly portable device that measures air particles like smoke, dust and other particulate matter in your surrounding environment. The reading instantly gives you a unique insight into the condition of your surrounding environment so that necessary action can be taken.

This device is sensitive to smoke even when the origin of smoke is far and can detect subtle changes to smoke levels.

In light of smoke pollution due to wild fires that we regularly hear in the news, it is a useful device to have so that you may check how much of that smoke has crept into your indoor environment.

Hoping to make the campaign a success with your help so that the product gets introduced to the market in near future. My goal is to make this device affordable to everyone on this planet, not just from first world. One need not break the bank just to know the quality of air they breathe!
