SuperHouse #38: DIY air quality sensor part 1 - "Basic" version 

Hi Jon!!! Glad to see you’re still kickin’.

Having a clean workshop is a great idea anyway, even better if it can help you be more comfortable. Another great video and explanation to go with it.

Awesome! Thanks for this, Jonathan!

I love this video, I watched it a couple of years ago to build a ESP air filter quality check, now I'm building another one and coming here to build it - thanks my friend! I really appreciate you sharing this knowledge

Awesome! I cant wait for the next video. Keep the good work.

Thank you SuperHouseDotTv. Great channel.

Very nice.. Thanks for the introduction to Air Quality Sensors.. Looking forward to next episode.. Greetings from the other side of the Earth (Denmark)

Looking forward to the next one!

Hello Jon! Nice to see you again, take care. Love from India :)

Great video, thanks.

Hi Jonathan...very nice video and informative.

Nicely done...

Brilliant! Would like to hear more on how to apply this technology for better health. Thank you

very cool!

Another awesome video, thanks so much. These might be very handy during bushfire season. I wonder if remote sensors could be used for early detection?

Very cool.

you're simply quite Legendary Genius

The world's best teacher

pointing at the switch of your soldering iron and then tell alexa to turn it on....The ultimate laziness....I love it :-D

Have you considered adding a HEPA filter to your workshop, controlled by the HA system in response to readings from the sensor? It seems like the perfect application for it, along with the graphs. Your graphs could even incorporate a variable to show the filter-fan's state so that you could see the delay effect between the fan coming on and the ppd decreasing. You could even PID control it :)

Great little project. I built my first one today and have plans to make a few more to monitor a couple rooms throughout the house. Do you know if there are any published standards for the ppd measurements?

Nice and tidy build! Beats my D1 Mini protoboard with a JST connector design 2-3 years back... I used ESPEasy for the firmware. Its a bit more fiddling but has a nice GUI and more settings for those that want them.

thx

As always a very good video. I've made myself something similar using a ESP32 dev board, SDS011 for PM 2.5 and 10 readings and a DHT22 for temp and humidity. I've used ESPhome as I find it easier for me and also the HA integration is seamless Later edit: the PM readings are quite precise as I've compared my results with an Airly (an independent air quality monitoring network) and they are pretty close

Oh man you’re awesome! I’ve just found you recently 😃 Where do you get these electronics from? I’m originally from Iran, back home we had some malls selling only electronics or computer stuff but since I came to Australia I couldn’t find any places like that. So I have to order everything online. But it could be much easier if I could walk around some shops and see where my curiosity and creativity takes me 😄 Thanks for your time 👍

Thanks Jon. Now feeding data into Node-Red. Thinking about using a Sonoff Micro to turn on and off at set time each day. Any thoughts?

Tasmota is truly an excellent FW. However I think that integrating devices in Home Assistant is better ESPhome FW because it is much more flexible than tasmota and does not require mqtt brokers. Excellent guide and congratulations.

This is really cool. I have one question though, how do you power your devices round the house, say you wanted to position this somewhere where there is no readily available socket to run USB power from? I'd love to take advantage of having all sorts of sensors around my house but I have no idea how to solve this problem.

Well done, great project. I just have little issues getting the MQTT data IoBroker.Sonoff Adapter. The data are not organized very well. Some are in seperate folders with units µg/m³ and some are just numbers. Did you try that or don't you use IoBroker. And I like that 3d printed case. Do you have that somewhere on Thingiverse? Or is it not for puplic use?

Hi,Jon great video, I think you need to explain at 15:30, 1decilitre = 0.0001 m3 .

You are awesome. Nice clean engineering with solid explanation and a very usable neat product at the outcome. I can do this myself when I build this, but what is the power draw so as I have some initial understanding of battery powering this.

Hi ! Thanks for this new video. I'm fairly new to tasmota, I used to create my own code but with yours videos I adopted tasmota 👍. So maybe a silly question, but is it not possible with tasmota to wake the d1 up (periodically or based on a action from the user) take some readings send the MQTT messages and go back into deep sleep mode? Looking forward part 2

I have a bunch of ESP-1 boards and would like to use it. Is that do able? great job.

Hi Jonathan and thanks. Convinced me that I have to build one soon. May be useful to warn users that with the release of v8.2.0 they now have to use tasmota-sensors.bin All best

Cool toy

Very nice indeed. Did you consider putting the usb c on the other side? Thanks, that is very cool as is! Looking forward to the next build with the display.

Nice project. Could you show us how to config thingspeak channel and their mqtt, with field syntax for the PM5003

Great little project - wouldn’t mind putting together the advanced version (where the laser isn’t continuously running) but without the display so I can pop it somewhere safe outside to see what I’m breathing when I step out the front door

Any experience or recommendation using the PMS7003 vs. the PMS5003? Besides the 3D case and physical aspects, does Tasmoto support this new flavor? Just re-up'd Patreon for your great work as well... ty

nice video, I'd recommend to check out esphome, it's the easiest and cleanest way to play with esp8266 devices.

Hi Jonathan, very interesting project, I'm glad that you mention that the refraction sensor will die rather quickly if it's running 24/7 :-) There is actually a very good project you should consider adjusting the design to, and that is feinstaubsensor from the luftdaten.info. It's a world wide project that started in Germany, and it measures particles. The preferred sensor for them is the SDS011, which is a bit bulkier, but i can actually support the Plantower as well. Further than giving values readable locally, it handles the 'scheduling' of the sensors, and it also reports it centrally. THey support both indoors and outdoors sensors :-)

Can you do the same whit a co2 sensor?

Great build including the 3D printed enclosure, Jon :) One strange thing was when I flashed the standard tasmota.bin (8.2.0, I didnt't get any sensor data. Upon checking the template on the Tasmota web interface GPIO2 was blank, PMS5003 was not listed as an option. I then flashed tasmota-sensors.bin (8.2.0) and that worked. Any idea what happened here?

i will come back to check the next video and......in meantime i am ordering pms5003!!

This is great. Can I do this with a Zigbee module?

Hey Jonathan, great project. Will build this. Will this work with an AWS IoT broker as well with the standard Tasmota.bin build? I'm building my MQTT infra around AWS not a local broker

What about a sensor for larger particles like Cat Litter (clay dust), Cat Hair?

You are amazing!!!! I would have a PhD if I would have had you as a teacher. You should be at MIT.

does anyone have any experience with the SM300D2? The co2 is Equivalent CO2 (eCO2) so I really don't care for it much and I'm using Senseair S8 for c02 anyways. I'm curious about the VOC and formeldehyde measurements of it actually. Does anyone know if they are any good?

@SuperHouseTV - are there known practical inferences we can make from the data being presented by the sensor device? What I am asking is, can you identify the type of, or specific particles as "shop dust" or "polen" or "Covid-19 virus"? I want to have the house tell me to take action when my shop gets too dusty, or perhaps turn on the air exhaust till the room clears out.

Power draw? Or: Might this plausibly be battery-drive-capable?

not enough smart device :) is possible to upgrade this sensor and make communication by wifi to google assistant?

Hi sir can you help me how to PMS5003 sensor concerted Stm32 blue pill Board and Program Arduino IDE

That’s a really nice case but wouldn’t it be better to bring the usb in from the other side so it doesn’t block the air flow?

Did you include the link to the Fritsch article? www.fritsch-international.com/fileadmin/Redakteur/Downloads/Reports_sizing/Introduction_Laser_Scattering/Laser_Scattering_-__introduction.pdf

because it shows number doesn't mean it's correct did you test it or compare it to other devices like laser egg+ etc?

Have you considered utilizing a sinus rinse? That stuff has saved my ass from getting serious sinus infections too many times to count. Once I found it...tried it...use it a few times a month on average but if I feel I'm getting messed up I immediately rinse...not taking any chances because I know how crappy and deviated my sinus cavities are. Sinuses suck

Add links to the components

There is a newer project with ready-made DIY solution with smart designed PCB and firmware: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-sjmF_RJ8nqY.html. One thing is to get values from sensors, the second to know how to evaluate them to automate ventilation. Firmware should be able to do the second part either.

interesting comparison of these cheap sesnors to 'real' a PM2.5 monitor. www.hindawi.com/journals/js/2018/5096540/ I wouldn''t trust the results of these, as the light scattering method is not a great method of measuring PM2.5. Would be interesting to put the sensor in a bigger box, and a dehumidifier on the inlet to the box to remove any moisture in the air. All the cheap sensors tend to over-estimate PM2.5 (by a factor of 3 to 4), however they do trend well with the reference method equivalent. I use TEOMs on an almost daily basis and they cost around $35,000. You may be panicking about your AQ when you don't need to. There are only three USEPA recognised methods of measuring particulates, and none of them are light scattering. Expecting decent results from something that costs $15 is well.. hopeful.

Sensirion SPS30 is order of magnitude better.

RE sinus, lookup MMS, Jim Humble, and curing that infection and eradicate the sensitivity for good. Hospitals and GPs won't help!

Next time put name of sensor to description.

Too bad you didn't talk about how it was tested by a competent third party and if it is reliable or not. LOL
