Reviews

SCD40 CO2 Sensor:
MiCS-4514 Gas Sensor:

The SEN55 particulate sensor is great for telling you about dust, pollen, and other particles in your air. Want to know if you should turn in your HVAC fan to filter your home air? Doing wood working in the garage? This will let you know when you might need to turn on a filter.

The optional CO2 sensor is very eye opening. Many people do not know the air in their office or bedroom reaches CO2 levels that have an affect on you. From poor sleep at night, drowsyness in the office, and brain fog can all be caused by high CO2. This sensor will let you know if your levels are getting too high and you need to turn on the air circulation or open a window.

The RGB leds are great for notifications. Trash night? Turn the LED green. Mail in the mailbox? Turn the LED blue. Air quality approaching bad levels? Turn red.

Product Details

The AIR-1Ā measures only 61mm x 61mm x 30mm and has an aesthetic design to blend in.Ā 

So what does the AIR-1 do?

PM1, PM2.5, PM4, PM10, VOC, NOx, Temperature, Humidity (SEN55)

**There is a temperature offset needed due to heat buildup from the ESP32-C3.
We are still evaluating it but it is between 2 and 6 degrees C.

Many air quality measurements from a very reputableĀ manufacturer. The sensor has a 10-year lifespan at continuous use (Most PM sensors only have 3 years) meaning you can have very short update intervals:

  • Monitor 3d printers
  • Turn your air purifier on when air quality becomes unhealthy
  • Detect new paint fumes

CO (Carbon Monoxide), C2H5OH (Ethanol), H2, NO2, NH3 (Ammonia), CH4 (Methane) (MiCS-4514 From DFRobot) - Optional

** Our beta test group has noticed the methane reading will spike when exposed to high amounts of other gasses. We all believe this is manageable for the vast amount of automations still but wanted to let you know. It is much more a exists/doesn't exist type of gas monitoring vs the actual PPM readout, it will read 0ppm in normal air.

(This device does not meet the requirements for gasĀ safety monitoring per the NBIC, NFPA, or IFC)

Monitor the individual gas percentages in your air with this optional add-on.

CO2 (SCD40) - Optional

This optional add-on brings a CO2 sensor to the package, which comes pre-calibrated and ready to use. (This device does not meet the requirements for CO2 safety monitoring per the NBIC, NFPA, or IFC)

  • Get alerts to open a window or automate your HVAC fan to run when CO2 levels are high.

Barometric Pressure (DPS310)

This pressure sensor feeds into the SCD40 (CO2) for more accurate readings

Bluetooth Tracker(ESP32-C3-Mini) - YAML Config Required

Track Bluetooth devices in your house, letting you know which devices are closest to the sensor. You will need to know the MAC of the Bluetooth devices you want to track.

  • Find your phone if you left it in the office or the bedroom.
  • Know who just walked into the room.
  • Track a beacon attached to your dog's collar.

RGB Pixels

Uses color-coded alerts for various home scenarios.

  • Flash red if the air quality is unhealthy.
  • Flash green on trash night.
  • Flash blue when it's treat time for your pup.

Power And Sensor Expansion Connector

A connector that'll allow future sensors and power methods. A few expansion boards are in development currently but no set release date. Let us know what you'd like to see on the expansion slots.

Best air quality sensor for Home Assistant

I LOVE this device. Its tiny, its quiet and its accurate. When I first got it, to say I was overwhelmed would be an understatement. It installed into HA with ease, but I was seeing all this data and I have no idea what any of it actually meant. I spent some time learning what the readings for each sensor were considered good, high or very high and to make mine and my wife's lives easier, I created a gauge card that is colored from green to yellow to red so I don't have to remember the numeric values. I can quickly look at the dashboard and see if anything is in the yellow or red and know they are high. There is also a blueprint for automations which I love, however I had to do some modifications to it since (and I'm on the newer side, so this might be something of my own doing) but I was getting a notification when something was high every time it changed. I set a condition that it would only alert once every 6 hours (except Carbon Monoxide since that is the most important to me).
I reached out to support for a question and they answered it quickly and concisely. If you're looking to monitor your air quality I highly recommend the air-1.

I regret paying extra for the gas sensor

The gas sensor is a bit overstated IMO - there's no way it is independently sensing all of those unique gasses. Between that and its questionable accuracy, I feel like I wasted my money.

Everything I was looking for

Only had it a week but already giving me useful information about my 3d printing fumes and the occasional gas leaking from the restaurant downstairs. Hoping it will help add weight to our complaints to the building about the restaurantā€™s poisoning us.

Fun device

Has helped us to be able to assess air quality and make changes re: home air filtration and improve air health. Plug and play, canā€™t complain!

Great but not plug and play if not using HA

I love the size of it and all the sensors. It definitely gives a lot of comfort to be able to understand the indoor air quality. I did not realize i'd have to host my own HA server to be able to see any data. That took a bunch of time and money as i ended up buying a intel NUC. Once set up though, it works smoothly. I like the incredible home automation options that open up with HA. Overall, a good mini project if you are comfy with tech. The only part that was unclear to me about the sensor itself was the adjustment i had to do with other sensors in my house as out the gate the temperature and humidity numbers were not accurate.

VK,

Thanks for your feedback and weā€™re glad youā€™re enjoying the sensor! Also, welcome to Home Assistant!

After connecting the AIR-1 to your network, you can access a built-in web portal directly at the deviceā€™s IP address. This portal lets you view sensor readings and control the device without needing Home Assistant or other platforms. However, for the best experience and advanced automation features, integrating with Home Assistant, Homey, or similar platforms is best.

The ESP32-C3 can generate some heat which affects onboard sensors. This is why we added the offset, which can help but it won't repalce a standalone temperature sensor. We do have a TEMP-1 temperature sensor so be sure to check it out!

Thanks again for your support, and If you need any help or tips, feel free to reach out!

Best,
Justin
