Hiii,

I read your post, it was reallly very helpful. But I have one question. CC320 is based on Wifi. There are other protocols 802.15.4 based device also which support beacons. Have you any idea about that? And there is a chip available for CC320. How you interface that??

Hi ravi, Nice presentation.

I may be missing something here but how are the...

4. TI’s BQ25504: As solar charger and battery management for outdoor unit.

5. TI’s LMP91000: As analog front end for low power gas sensing.

6. TI’s HDC1000: As temperature and humidity sensor module for indoor and outdoor unit. TI’s TMP112 temperature sensor for indoor and outdoor unit.

part if the hardware "provided" for as part of the challenge?

[mention:e95cffeb0a3c41eb97fab167df4e3772:e9ed411860ed4f2ba0265705b8793d05] my apologies but can you add somthing here?

Thanks,

Ravi

It's a well thought out process and detailed plan on how you intend to achieve it, but unless I'm missing something in your introduction you haven't said WHAT it is your system will be aiming to do.

...... to maintain air quality inside home.

.... sensing and controlling Air quality and water quality for Breath Easily and Healthier Living

I'm guessing you will be " manipulating the internal environment to be healthier than the external, and warning (the occupants ??) if it exceeds a certain threshold ".

re TDS

For the uninitiated (and us who have good water) you may also want to elborate on what TDS is and how it affects the occupants/users.

Are you intending to sample it before it gets into your storage, and shut it off, or what do you do when it is higher than desirable.

(I'm guessing your only option is filtering or bottled water).

Our well water is filtered by a one micron filter, due to higher iron content which tends to stain everything.

re the car power window motors.

You may find windscreen wiper motors are just as powerful, and possibly much cheaper, since they seldom wear out.

Good luck, this application has some very useful features that are applicable in many situations and countries.

Interesting project.

Are you going to be able to check for VOC's in your water or just the air?

Have you considered adding an air filter to bring in outside air but clean it if it is less than clean?

Might be a useful option when you need to cycle new air into the house.

An excellent presentation. I am working on a PhD that will use smart home tech and some of your ideas could come in useful, if that is OK?

Ravi;

With your gas sensors, are you wanting an exact ppm or mg/m^3 measurement or just an indication when you go over a threshold?

Hi Ravi, I enjoyed your presentation and I like your idea to measure indoor and outdoor conditions. I will look forward to seeing your interface between the car window motors and the windows and ventilators.
