Hope to try Airgradient Go soon.

I hope the display will be e-ink! Thank you
What kind of battery will it have? My Aranet uses 2 AAs and the battery life is much longer than any USB-charged product I’ve used.
It will use a pouch battery with USB charging. We looked at more standard sizes like AA and 18650 batteries as we wanted to use them for the sake of repairability, but we couldn’t find a good way to keep the device relatively compact and have decent battery life with these battery sizes.
With that said, the Aranet is able to have an incredible battery life because it only houses an NDIR sensor. These are already very low power sensors, and the SenseAir Sunrise is further designed for minimal power consumption. The issue in multi-pollutant devices is the PM sensor, as these require vastly more power to run. This is the reason that portable PM sensors like the AirBeam or Atmotube Pro always have significantly less battery life than dedicated CO2 monitors like the Aranet4 Home or INKBIRD IAM-T1.
How durable will this be? My interest is wearing the GO at work where it may constantly hit things as I move around.
Will it have PD fast charging?
Thanks for the question @Austin_Richards! From my personal testing of the enclosure over the past few weeks, I can tell you it is quite durable already on the pre-production units. Durability is a big focus for us as we’re designing it to handle real-world use, including more demanding scenarios like being worn during active work (e.g. firefighters measuring smoke exposure). So the goal is that it can take bumps and knocks throughout a normal working day without issues.
On charging: it won’t support PD fast charging for now as fast charging tends to generate more heat.

Will the AirGradient Go be tested and certified, similar to the fully assembled AirGradient Indoor/Outdoor monitors? If so, will they include a test report?
Some ideas addressing practical usability:
- Please add options to chose measurement selection, rate and strategy – for both connected and mobile use –, to allow to conserve mobile power as needed. Extended example geared toward mobile use: let us select GPS update frequency depending on movement speed, let us select PM sensor reading depending on moved distance, …
- Same goes for conserving memory if you need to stretch available memory over a certain time…
- maybe allow internal memory expansion using an inexpensive microSD card for those who need it?
- you might want include an inexpensive accelerometer to guess when to take the next GPS reading, or at least how to adjust the GPS update frequency
- allow to configure for minimal charging in order not to disturb the temperature/humidity/[…] readings
- allow to charge by simply placing the monitor in a dock (sold separately?) which can stay connected to USB power or…
- …even better: give this dock an additional solar cell input connector, with efficent power conversion to take most out of the available radiated power… and if charged by solar power, let the monitor know that it might/should maximise charging speed…
- BLE data access protocoll: implement queries using time (span) and/or area as selector/key; that way you can easily check the values for certain spots or time intervalls… (depends on device memory and download speed – if it’s fast enough, it’s easier to sort that out on the receiving end…)
Hi @cosmic_driftr,
Yes, this is the intention! It will take a while to get certifications, but they will come with a test report similar to our other pre-built devices.
Hello AirGradient team,
Are there any plans to offer a more affordable “kit” version of the AirGradient Go, similar to the Indoor and Outdoor monitors?
Will it be possible to use the AirGradient Go without the battery installed, powered only via the USB port (for example, once the battery is no longer functional)?
Will the pouch battery be user-replaceable? If so, will it be a commonly available (standard-like) type, or only available through your shop?
Thank you!
Hi @TMan - at the moment we don’t have plans to offer the Go as a kit version as the assembly is complicated but if the assembly becomes simpler in a future version - I could see it being offered as a kit version.
Will it be possible to use the AirGradient Go without the battery installed, powered only via the USB port (for example, once the battery is no longer functional)?
Yes, you can power the Go without the battery. We have pass through charging as well so if you leave it plugged in, the battery won’t be damaged.
Will the pouch battery be user-replaceable? If so, will it be a commonly available (standard-like) type, or only available through your shop?
We try to use commonly available parts as much as possible. Yes, the battery is user replaceable.
Will the companion app support smartwatches? Specifically WearOS

Hi @Austin_Richards, to my knowledge, we currently don’t have a plan for wearable device support yet. But I’ll make sure that I bring this up with our team as it’s also something I’ve been thinking about. I have a WearOS watch, and it would be handy to see the air quality metrics on our wrists.

Does AirGradient support some level of DIYing? I’ve made a portable formaldehyde sensor that I would gladly retire in favor of something more streamlined. Will I be able to retrofit the device with a Sensirion SFA30 or (once they come out) SFA40 unit?
Hi @friedmike, welcome to our community!
I’ve passed your question on to our engineering team. They’ll get back to you soon.

Hi @Austin_Richards, I hope you are doing well. I have some updates on the wearable app. We are planning to make our companion app support the Apple Watch in the future, and also the WearOS. The estimated timeline is likely towards the end of the year.
Do you have some features in mind that you would like to see in the wearable app? We would be thrilled to discuss this with you and everyone interested in the wearable app!
Hi @friedmike, We really love DIYs and we design the Go to support that ideas. The Go includes an I2C port for sensor expansion. Please note that the space inside the device is limited. You may need to remove some existing sensors on the board or modify the device enclosure.
We do not currently support formaldehyde sensors in our official release firmware. You can make a change from our source code available on GitHub.

For me the Android Wear feature I would want is support for tiles & complications so i could glance at the readings

Hi @Austin_Richards, thank you for your suggestion. I have taken a note about this for our developer!
