Here's how we connect the IKEA VINDRIKTNING Air Quality Sensor to #RISCV #BL604 ... And read the PM 2.5 data with Apache #NuttX OS

Bus Pirate sniffing the UART output from IKEA Air Quality Sensor

https://lupyuen.github.io/articles/ikea?16#appendix-test-with-bus-pirate

@kreyren IKEA uses the PM1006 Sensor, which is a cheaper version of PM1006K.

On PM1006K we get more data fields: PM 1.0, PM 10.

These fields are not available on PM1006, hence they are unused.

@kreyren That's the UART Output from the IKEA Sensor, we don't need the UART Input. We will see the PM 2.5 data when we dump the UART Output as hex:
