To set up your Qingping Lite, follow these steps
Download the Qingping+ (basic) or Qingping IoT (advanced) app on your phone to access monitor settings. Connect the monitor to the app (instructions in the documents section) and check for any firmware updates. Review the default settings: Auto calibrate CO2: Ensure the device is exposed to 400-500ppm CO2 for a few hours each month by taking it outside or placing it near an open window. If necessary, reset the CO2 sensors in the app settings. Auto switch off and screen auto off: These settings help preserve battery life by turning off the device when not plugged in or during the night. To continuously record readings, adjust these settings in the app.
