INKBIRD APP
As with most apps the INKBIRD one first requires you to pick the device you want to setup.
This is a Bluetooth device so as long as Bluetooth and location services are enabled on your smartphone (and of course Bluetooth is turned on the IAM-T1) you will locate it as seen above.
Once the app is done detecting the device it will be listed on the intro tab.
The very first tab gives you a quick look on what the sensor inside the IAM-T1 is currently reading including CO2 PPM, humidity, air pressure (don't know why INKBIRD didn't include this on the screen) and temperature.
Inside the settings you can change the temperature unit (Celsius, Fahrenheit), change the name of the device, check CO2 levels graph (showcase), set the sampling interval, enable the CO2 alarm, check for new firmware updates), switch between light and dark mode, check the user guide and remove the device from the app.
From the calibration tab you can either choose for the device to perform an automatic calibration or adjust numbers manually.
Moving to the app alarm tab from here you can set alarm thresholds for CO2 levels, humidity, temperature and even air pressure.
Finally, you can export data from the data tab.
