Table 8.
Power consumption of embedded sensors on the test platform depending on the scenario: OFF or Low Power (LP) mode. Why does text in the columns not wrap?
| Scenario | Consumption | |
|---|---|---|
|
Static mode (A) |
nRF52 configuration: OFF Mode BLE communication disabled All peripherals/GPIOs disabled |
760 µWh Pavg = 0.76 mW Pmax= 0.76 mW |
|
Dynamic mode (B,C) |
nRF52 configuration: LP mode BLE communication enabled Sending connection request (advertising packets every 1 s) Sleep mode for internal sensors |
3.9 mWh Pmax = 52 mW |
|
Dynamic mode (D) |
nRF52 configuration: LP mode BLE communication enabled Mode connected + notifications enabled Waiting sensor notification (L2CAP packets every 100 msec) Sleep mode for internal sensors |
4.1 mWh Pmax = 29 mW |
|
Dynamic mode (G) |
nRF52 configuration: LP mode Mode connected + notifications enabled Inertial Measurement Unit (IMU): acquisition measures (accelerometer, gyrometer & quaternion) + sending data (20 bytes) at 10 Hz T&RH sensor: sleep mode Analog-to-Digital Converter: sleep mode |
42.8 mWh Pavg = 43 mW Pmax = 78 mW |
|
Dynamic mode (F) |
nRF52 configuration: LP mode Mode connected + notifications enabled Accelerometer: sleep mode T&RH sensor: acquisition + sending data (4 bytes) at 1 Hz Analog-to-Digital Converter: sleep mode |
4.2 mWh Pavg = 4.2 mW Pmax = 29 mW |
|
Dynamic mode (E) |
nRF52 configuration: LP mode Mode connected + notifications enabled Accelerometer: sleep mode T&RH sensor: sleep mode Analog-to-Digital Converter: acquisition + sending data (16 bytes) at 10 Hz |
6.7 mWh Pavg = 6.7 mW Pmax = 45 mW |
