Custom ESPHome external component for Cubic **PM1006 / PM1006K** optical particle counter sensors that broadcast **4-byte continuous frame streams** over 9600 baud UART, rather than responding to s...

Long story short I’m in the process of building an outdoor air quality, temperature, humidity, pressure, and motion sensor setup for my front porch. One is the PM1006K which is a cheap (10.00 on Amazon) pm2.5 sensor. It’s supposedly used in some consumer air filter systems and a review said it worked with ESPHome… well it does after a ton of poking and prodding with a little flogging of the wires.

The link is to the github page where I have the final product posted. I know there are better sensors available but they tend to run more and the really good ones use a laser sensor and burn out over time so it becomes an ongoing (some only last 8000 hours) expense.

This one is a DC01 Infrared PM2.5 Air Quality Sensor. And I’m pairing it with a DHT22 for temperature and humidity, a BMP280 temperature and barometric pressure sensor, an MQ-2 + MQ-7 + MQ-135 for hazardous gasses and smoke, and a BH1750 light sensor, a AM-312 + a HC-SR04 for motion detection. All running on an ESP32-S3 which is also acting as a Bluetooth Low Energy proxy.

All the code will be able to be found at https://github.com/nightshade00013/MuttMutt-ESPHome when it’s 100% completed. But being the pm2.5 working correctly was a huge step in the right direction. And the main reason why I am posting this now so others who are interested in building a cheap sensor can get started.

      May as well, lol. When the house is done I should have a decent cash flow positive enough to be able to spend more time diving and traveling.

      I’m using wled and just have random things that play and I manually set different ones on certain holidays. Nothing super fancy. I will eventually add more strips and light the whole house… may even attach to my soalar racking with a few strips. I have concrete headstones for Halloween and will be making a couple more but I am not sure if I want to run lights on them. Eventually my front yard will have a couple fruit trees with a pergola to put some on. After that I will probably look at a light show. The house is a semi craftsman style so I’m considering downlighting the side walls with a strip instead of going along the edge of the roof. With a white house it can be any color I want at night.

      For Christmas I do have a couple things that are lit up. My other half bought a couple wire lit yard things that I have installed WS2812B fairy lights in and I made a WLED sign that says Merry Christmas in the same fairy lights. At some point I’m going to do a Christmas tree the same and mount it somewhere in the front.
