Airlytix ES1 is an ESPHome air quality/environment sensor that I've been working on few a little while now
My main goal was to get a bunch of air quality sensors into a nice small form factor that could sit on my desk
The sensors include:

thats looks very clean and professional

thanks, I've been working on it for a couple of years, although house moves and job changes did get in the way

bravo! Looks awesome

Is this suitable for outdoor use?

Not with the current case design, it would need quite big changes to make it waterproof

One thing I noticed with my CO2 sensor next to my couch is that being in close proximity skews the readings. Something to look out for if it's on your desk.

Just out of curiosity, what do you do with the data given by this sensor, like do you have some good examples of automations based on the readings?

Mine arrived! Pretty quickly too - only 8 days from UK to Australia via royal mail. Very happy with it so far.

How do you avoid false temperature and humidity readings given that the ESP emits a lot of heat into the box, compared to other types of devices?

There's two temp and humidity sensors, one is located in the PM module which has a fan drawing fresh air, the other is on the pcb with the esp32 but opposite side (directly behind one of the holes on the right). Averaging between these two gives a pretty reliable reading

At the moment I'm mostly using it as a reminder to let some fresh air in. I'm going to use the light sensor to automate room lights and blinds. Mostly the readings are just fulfilling a curiosity, I wish air con was more popular in the UK as it would be good for controlling that

Hm, the light is actually not a bad idea, I've been looking at getting smart blinds just recently. Maybe a sensor like that is a good way of controlling blinds

Cool beans, this is a great idea, and since this is receiving USB power, the fan poses no battery problem.
Have you considered the BME688? You get temp, hum, and air quality with very broad spectrum gas detection. I am using it inside my Prusa MK4 build:

@vagrant saffron the config it comes with allows you to set a temp offset so if you have a reference temp sensor you can calibrate it. I noticed my temps read a little high so I'm going to do this for mine.
And I don't think it's such a good idea to add another item to the Bill of Materials like the BME688 since there's actually THREE temp/humidity sensors already:

The main problem with the offset is that the effect of chip heating on the temperature sensor is nonlinear, so an offset is not going to cut it, nor would calibrating at two known temperatures.
Anyway, just something to keep in mind. In general if you'll have a thermometer chip somewhere in your design, it best be away from other electronics and sit below them so that any cooling air draft (no matter how minimal) will tend to make ambient air flow up and through the sensor first.

A fixed offset is a good first approximation that would probably be close enough for majority of people's needs. It's all ESPHome so you can write your own custom lambda and reflash if you can come up with a correction function.
