Idea: by default, the light only shows one quality indicator, but the particulate matter sensor datasheet shows that it can output PM1.0, PM2.5 and PM10 values too. You could fit an ESP8266 that reads out the raw PM categories and publish them over WiFi, e.g. using a home assistant compatible protocol. | |||

What
This page is about hacking the IKEA VINDRIKTNING PM2.5 indicator light.
Hardware
- power is by USB-C probably 5V
- the particulate matter sensor is the Cubic PM1006K
- appears to have two LEDs (red and green) so it can indicate colours green, orange and red
- the sensor output can be PWM or UART, the UART output provides PM1.0 PM2.5 and PM10 values
Pictures of its internals: https://twitter.com/guido_burger/status/1413900622919872521
- there is a footprint for a kind of debug header, with signals ISPDA, RESET, ISPCLK, GND, +5V
- there is an internal header with signals LED_G_1, PWM_Fan, LED_R_1, FAN-, FAN+
- there is a separate header for the fan with signals FAN+,FAN-
- there is an 8-pin IC, could this be the "main" microcontroller?
Hacking
Idea: by default, the light only shows one quality indicator, but the particulate matter sensor datasheet shows that it can output PM1.0, PM2.5 and PM10 values too. You could fit an ESP8266 that reads out the raw PM categories and publish them over WiFi, e.g. using a home assistant compatible protocol.
