If any of you have missed IKEA has a “new” product called Vindriktning. It is a 2.5 PM air quality sensor (PM1006) with a color LED on the front to indicate the air quality with green, amber and red colors.

By default the device is not a smart or connected device but thanks to some clever people it is a perfect base for a DIY project.

First of all @Hypfer published his esp8266 code base and instruction how to connect and set up the device with an esp8266 and MQTT.

Then @Habbie took it further and made a PR to ESPHome to include the PM1006 as a 2.5 PM sensor in the ESPHome project. Since that many has tried to solder an esp8266 or esp32 to the Vindriktning and succeeded with the project.

Some pictures are available in the PR’s discussion section, but please do any follow up discussion here to leave the Github PR clean of any further discussion.

Tagging @lassebm, @sermayoral and @Abeltje - can you share your project pictures here as well?

Special thanks also goes to (referenced from @Hypfer’s original work):

Thanks @Habbie. The PR to the ESPHome is well appreciated. I think this device will be a top seller from IKEA to any DIY project.
I installed a Wemos D1 Mini and a DTH22 shield inside my device and with ESPHome it was just a few minutes to make it work, after the struggle of the soldering and trying to place everything to the right place…

I am just waiting now for an article from Hackaday… :wink:

Anybody who posts photos, please let me know if you’re okay with those ending up in the esphome docs!

Like this one?

Kinda funny because I saw the hackaday article yesterday and then found this thread this morning.

Really cool. Maybe I’ll have time this winter to play with this.

Damn… That was quick… I came across @Hypfer’s Github repo first, just a day after it was published, because Google suggested it on one of the cards in the Chrome Mobile browser when you open a new tab.

Otherwise it is an easy project. You just really need some dupont cables and an esp8266 or an esp32. (And a good soldering iron.) Smaller is better. Actually the Wemos D1 Mini is a perfect choice by small size. Esp32 has some really tiny boards as well. Like the Atom Lite ESP32 or the Wemos ESP32.

@sermayoral - in the Hackaday article’s comment section @Hypfer was discussing the importance of the fan and fan speed with another user. Have a look on that.

Feel free to use mine:

I used an old ESP8266 NodeMCU v2 from the drawer and connected it all up as listed below.

IKEA Vindriktning NodeMCU pin Note
PCB +5V pad VIN NodeMCU v2 support 5-10V
PCB GND pad GND
PCB REST pad D2 UART TX from PM1006 sensor
Fan +5V (red wire) 3V3 Fan will run constantly and quietly
Fan GND (black wire) GND

Example YAML (ESPHome >= 2021.8.0 required):

uart:
  rx_pin: D2
  baud_rate: 9600

sensor:
  - platform: pm1006
    pm_2_5:
      name: "IKEA Vindriktning PM2.5 sensor"

Thanks @GSzabados for creating this thread. Its the proper place to speak about it.

In my case i have used an esp32u to put an external antenna in order to read all the Xiaomi BLE Thermometer of my house.



I have to replace the antenna by a white and smaller one, but i only have the black one in my house. The ble coverage is really good. I wanna change the fan voltage as well, so i will post more photos when i open the vindriktning again :blush:

@Habbie you can use any of my photos, of couse :+1:

Sergio, I don’t see an ESP32 on your photos - which board did you use and where did you put it?

I have use an ESP32-U like that

You are right. I only took photos before putting the ESP32 inside. I had to cut the pins to fit in the hole. If you are interested, i can open the vindriktning to take photos. Is not a problem :blush:

I’ve noticed that one of my boards would also fit if I cut the pins :smiley: I’m curious yes, if it’s not too much to ask!

(meanwhile I have orded wemos d1 mini-sized ESP32 boards)

Of course. I will do it

By the way, its very interesting to desolder the ESP red led to avoid this:

Both Wemos Mini Esp8266 and Esp32 has only the blue led, but I guess your real choice was for the antenna connector. But I have seen some other projects (Zigbee coordinator) where the built in antenna was cut through and an external connector soldered in place of the cut. Wouldn’t that be easier for you as well?

hah, yes. I have some ESP32 boards (LOLIN32 I think) that support a battery, and they will blink red (or was it blue? if they don’t see a battery. I have since gotten other boards without battery support to fix that, but they don’t fit nicely inside the IKEA unit, so now I’m waiting for the smaller ones.

Any idea how long the sensor lasts for?

Some of the other ones have quite a short life (circa 12months) but you can do life extension tricks…

Anyone seen measurements side by side with a higher quality sensor?

I’ve just set up my pms7003.

I used an ESP8266 ESP01 with a stepdown converter (5v-3,3v). Also I didn’t use the solder pins like everybody else did, i used the solder pins at the end of the board. I think they are pins to accommodate a connector which is not on the board from the factory but they perform the same.

Ikea board 5v and GND → Stepdown
Ikea board REST → GPIO2 on ESP
Stepdown 3,3v → 3V3 and EN on ESP
Stepdown GND → GND on ESP

YAML config:

# Ikea Vindriktning PM2.5 sensor
uart:
rx_pin: GPIO2
baud_rate: 9600

# External component until final merge

I used a hot glue gun to glue the pcb’s to the casing. These glue guns can be bought at your local hardware store or at your local Action (NL).
The reason why I used two little pcb’s is (1) I had them laying around and (2) they minimally disturb the airflow for the sensor.

To get the air quality data into HomeKit the name of the sensor must contain: ‘pm25’.

Side note: I’m running my first config from before the icon was changed. You should use:

ESPHome has merged the component - you can view the docs at PM1006 Particulate Matter Sensor — ESPHome now!
