EM2-Wakeup->Measure Data->Transfer Data->EM2
Assuming a 10 minute cycle, 30s in EM0 mode and 570s in EM2 mode with Radio on
EM2 - Full RAM retention and RTC running from LFRCO in precision mode
| State | Current (mA) | Power (mW) | Weight |
|---|---|---|---|
| EM2 | 0.7 | 2.31 | 0.95 |
| EM0 | 6 | 19.8 | 0.05 |
The average currents for EM2 and EM0 have been referred from IoT project numbers.
Weighted Average of Current = 0.965mA, at 3.3V Weighted Average of Power = 0.965 * 3.3 = 3.1845mW
BME280
In weather monitoring mode.
| State | Current (mA) | Weight |
|---|---|---|
| Deep Sleep | 0.0001 | 0.98 |
| Active | 0.7 | 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
ENS160
| State | Current (mA) | Weight |
|---|---|---|
| Deep Sleep | 0.01 | 0.7 |
| Active | 29 | 0.3 |
The sensor needs 3 minutes to warm up, considering one measurement every 10minutes
Weighted Average Current = 8.7mA, at 1.8V
AS7331
| State | Current (mA) | Weight |
|---|---|---|
| Deep Sleep | 0.001 | 0.98 |
| Active | 2 | 0.02 |
Needs about 70ms to wakeup and measure data.
Considering one data measurement every 10 minutes.
Weighted Average Current = 0.0401mA, at 3.3V
