I really like to have all AQ Monitors and other devices connected to one place in order to make my life easier when I try to figure out what is going on in my house. I am an iOS user which means this post doesn’t concern Android users, however, I will advise you to stick around and read the benefits of having Apple HomeKit.
Not all AQ Monitor manufacturers support HomeKit and here comes HomeBridge which is a platform to bring non-supported devices to Apple’s ecosystem. There are only a few AQM manufacturers that officially support HomeKit, like Kaiterra, Eve and QingPing.
The community of the HomeBridge has allowed others to take advantage of the platform and make the user experience even better by porting many more AQMs into HomeKit.
During and after the wildfires on the west coast of the United States the PurpleAir II (PA-II) network of low-cost monitors grew exponentially and has reached a number of about 11000 units. The reason was simple, people wanted to see when it was safe to go outside and/or open the windows.
Although the PA-II is a small cute particulate matter monitor, it has a flaw. The temperature and humidity sensor (Bosch BME280) is placed too close to the rest of the electronic components. As a result, neither the temperature nor the humidity reflects the real values of these environmental parameters. All electronics produce heat, and they may interfere with other sensors, and this is the case with the PA-II.
By the time someone invests money on a device with an array of sensors they want to be able to take valuable measurements for all the parameters. For this reason, I figured out how to improve the temperature and humidity measurements in order to reflect the real conditions outdoors or indoors as some people place the monitors indoors too.
It is easy to take apart the device, as there is only one screw. Once it is unscrewed, you need to pull the sensors out of the white case. Don’t worry because they are holding each other with some stickers.
There is a demand for Green Buildings lately, which focus on the comfort and health of the building’s occupants. Energy efficiency was the original target for most of the green buildings certifications programs, but they have evolved, and they now focus on many more aspects of the indoor environments. Indoor Air Quality has become the number one priority for many green building certifications, and in order to be certified, there are strict rules for ventilation and AQ monitoring.
Here comes Kaiterra Sensedge Mini, which is a RESET certified indoor air quality monitor. The Sensedge Mini is a calibrated real-time monitor that has to be placed in buildings that wish to obtain a Green Buildings certification.
The Sensedge Mini uses two removable sensor modules to replace the traditional, costly calibration processes for long-term accuracy with minimal maintenance.
