Default Mode is a power saving and life-prolonging mode for the PM2.5 sensor. We recommend this mode for normal day to day usage. In this mode, the Node/Pro will take measurements every 10 seconds when actively being used (i.e., whenever you press any buttons on the device, this will be registered as 'active use'). After 10 minutes of inactivity, when the screen is still on, the Node/Pro will change to take measurements every 3 minutes. Meanwhile, at any time when the screen is off, the Node/Pro will take measurements every 15 minutes.
Continuous Mode is the recommended mode for taking measurements throughout an experiment. In this mode, the Node/Pro will take measurements every 10 seconds - making it quick to detect changes in the environment.
Custom Mode is an optimized mode enabling you to select your preferred interval of measurements, between 3 minutes and 1 hour. The sensor will take measurements at the selected interval, however when the Node/Pro is being actively used the sensor will take measurements at 5 second intervals for a short period of time.
