Pulsa sensors
The IKEA Vindriktning consists of two separate modules. The Datasheet states ☒0μg/m³ or ☒0% of reading so not really unexpected. I have set up 3 sensors purchased on the same day (so chances are, same batch) and compared their readings with all three sitting next to eachother: The accuracy can be all over the place when considering the range relevant to indorr-usage (0-100µg/m³).

I have adapted the physical wiring to make transition easier.

This approach does not talk directly to the sensor module but rather listens to the responsens from the PM1006 sensor module sent to the LED board and parses the output. Capture nummerical readings by tapping into the debug port of a IKEA Vindriktning Air Quality Sensor module and expose the readings to Home Assistant.
