That is a good question, the Philips has PM2.5, AQI and Indoor Allergen Index. The Xiaomi, no idea at the moment. I need to check.
No, I haven’t compared them.
Can you plot them on a history chart etc? Might get a clearer picture of relationship and whether it needs an offset or linear calibration etc…
You can just cut the black cables and use them instead of the pads.
Did you modify the fan voltage?
Interesting.
If you plot them both on the same chart they will be easier to compare, but you still get the idea like that.
Sometimes I use Grafana, and then you can tinker with offsets (say add 10) and linear scaling (say multiply by 0.9) on the fly until they line up …
Nice work comparing these! Semi-related question: How did you get the SPS30 to work with esphome? I only get extremely high values, like this:
Did you encounter anything like this?
I haven’t experienced any issues with the SPS30 sensor. Just use the SPS30 component. SPS30 Particulate Matter Sensor — ESPHome
Used this, GitHub - paulvha/sps30: Sensirion SPS30 driver for ESP32, SODAQ, MEGA2560, UNO, ESP8266, Particle-phot , as standalone before, and it worked just fine as well.
Apparently I had connected it to 3V instead of 5… Up and running now.

Pleeeeeenty of room for more stuff inside!!! I manage to install a mhz19 (temp and CO2) and a MQ-9 (CO)
After a few days working very well I´ve decided to open a wee hole for the MQ-9 because of the heat it generates, not much tho but it affects the MHZ19 temperature sensor.
This is my esphome code

Was thinking of doing something similar, but then I would like to control the LEDs myself, so that they become orange/red when the CO2 level rises as well, but since those are not controllable I have not begun that project yet.
That should be possible, you just need to cut the leads running up to them with a sharp screwdriver and wire them up to your board.

Hehe. True that! Will actually try that out.
Thanks for share the way!
It’s really easy connect to ESPhome & HA
I also put DHT22 in it, here’s my setup & code:
esphome:
name: ikea-pm25
platform: ESP8266
board: d1_mini
# Enable logging
logger:
# Enable Home Assistant API
api:
ota:
wifi:
ssid: !secret my_ap_ssid
password: !secret my_ap_password
# Enable fallback hotspot (captive portal) in case wifi connection fails
ap:
ssid: "Ikea-Pm25"
password: !secret the_ap_password
captive_portal:
uart:
rx_pin: D2
baud_rate: 9600
sensor:
- platform: pm1006
pm_2_5:
name: "PM2.5 sensor"
- platform: dht
pin: D5
temperature:

humidity:

Hi guys!
Have you noticed that your reading will either stay the same for very long time or will change to unknown after home assistant reboots?
I’m, running esp32 with esphome, with config same as everyone else’s above 
Thanks for any input!
Great solution!
I would be very grateful if you could share your yaml configuration
Tasmota now supports Vindriktning. Currently it is required to compile your own firmware with
#define USE_VINDRIKTNING
Result

How are the 3 different values? Full RX/TX UART support?
@Habbie, you might want to have a peek on this…
Full RX/TX is in pm1006: add support for sending a measurement request by Habbie · Pull Request #2214 · esphome/esphome · GitHub
I also saw the two other numbers in the data frame from the pm1006, but the datasheet does not say what they are, so I did not make a separate sensor output for them. If somebody has good information on what they are, we can add them, of course.
(reading calculation appears to be wrong · Issue #3 · Hypfer/esp8266-vindriktning-particle-sensor · GitHub has some earlier discussion on the other numbers in the frame)
