Configure Apache #NuttX OS to enable UART1 for 9600 bps ... So NuttX can talk to IKEA Air Quality Sensor

Now we connect IKEA Air Quality Sensor to #PineDio Stack #BL604 @PINE64 ... So we can transmit PM 2.5 readings over LoRaWAN to The Things Network!

Here's how we decode the UART Output from IKEA Air Quality Sensor ... Based on the PM1006 LED Particle Sensor Datasheet

Here's the datasheet for PM1006 LED Particle Sensor inside the IKEA Air Quality Sensor ... Let's use this to decode the UART data

@lupyuen ain't the plantower things much cheaper in comparison to the ikea one?
@kreyren I'm just experimenting with a cheap off-the-shelf IKEA Sensor ... And see what we can do with it 🙂

@lupyuen why not build one from scratch instead? I am currently building one:
IKEA Air Quality Sensor sends something on its UART Port ... Let's capture the binary data with Bus Pirate
https://github.com/lupyuen/ikea-air-quality-sensor#test-with-bus-pirate
Here's how we soldered the UART Port on IKEA Air Quality Sensor
IKEA Air Quality Sensor exposes a UART Port ... Let's sniff it with Bus Pirate
https://github.com/lupyuen/ikea-air-quality-sensor#test-with-bus-pirate
Let's connect IKEA Air Quality Sensor to #LoRaWAN and #TheThingsNetwork ... With Apache #NuttX OS and PineDio Stack #BL604!

@leviathan Probably not right now, but lemme experiment and learn some more about particle sensors 👍

@lupyuen Also:
In case you're interested, some of my friends from back in Hong Kong and Shenzhen kind of ended up here in Europe as well (most are in Londong, I'm in Portugal), and we're starting now a new startup here (with me as diversity-鬼佬😂 )
Meetings are in Cantonese or 普通话 when I'm around😌 (我的广东话不好😅 )
Maybe you wanna join?😉

@lupyuen That's ok!
We were going to do the same, but maybe you wanna try figure out how to adapt it to measuring 500nm particles and less?
It's an open source project!
@leviathan Hmmm sorry I'm not so familiar with particle sensors, I just bought one from IKEA to experiment

@lupyuen Friend! You might be our rescue!
We need a particle sensor for our LibreSilicon clean room project, as explained here in my video about LibreSilicon, from that timestamp forward:

Maybe you can help us with that?
