1. In this mode, the device consumes minimal power. The MCU is in an off state and does not respond to any commands.

2. When a measurement is needed, pull the enable pin low to switch the device into normal working mode and automatically perform one measurement.

3. After the measurement is complete, pull the enable pin high to return the device to low-power mode, with power consumption below 3mW.
