Ambient Air Quality Monitor



Monitor the outside air quality for any unhealthy air.

Use the measured data to:

1. Warn through voice if the level measured is above a certain setting while driving.

2. Warn through voice when stopping the car if the measured level is above a certain setting.

3. Automatically enable air filter function (e.g. Biodefence Mode) when judged necessary.

4. Automatically report measured data to cloud services for live detailed dynamic street level monitoring of areas far superior to current air quality measurements.

This is a particular attractive feature for markets like China and others where especially urban conditions of air quality can reach concerning levels.

A range of different air quality metrics can be monitored and the tradeoff between cost, precision and substances/particle sizes has to be evaluated.

Besides the practical values of this feature, it also emphasizes and builds upon the brand value of zero emission cars and the aim of cleaning up street level air quality.


This feature has no competition and addresses those caring about air quality.

Moderator: Some sensors can relatively cheap to detect one specific pollution component like CO2. To provide an broadband measurement, systems can cost tens of thousands of dollars to perform reliable air quality analysis. These products may also require frequent calibration and/or sensor replacement as the devices get contaminated by the particles and gases they are measuring.

Additional comment: BYD is already deploying air quality sensors in their cars (e.g. BYD display)

I wouldn't care much about CO2 in this context. That's more of a climate change concern.

Rather I would care about particulate matter, especially PM 2.5, that normally an air filter is aimed to capture. Surely lots of sensing abilities can be added but to keep it cheap, you could start with something on the level of already mass produced consumer products.

For example:



I doubt the sensor cost is more than a few US$ for basic particulate matter sensing.

Example of sensor:
