Weather Monitoring mode

  1. Sensor mode : Forced mode - 1 sample/minute
  2. Measurement time : 8 ms
  3. Output data rate : 125 Hz
  4. Current consumption(typ) : 440 uA
  5. Power (for 1.8 V) : 792 uW

In weather monitoring mode.

State Current (mA) Power Weight
Deep Sleep 0.0001 0.33 uW 0.98
Active 0.7 2.31mW 0.02

Needs about 8ms to wakeup and measure data.

Considering one data measurement every 10 minutes.

Weighted Average Current = 0.01437mA, at 3.3V Weighted Average Power = 0.0474mW
