Table 8
Power consumption of the circuit before and after the sensor is added.
| | Current consumption (max.) (mA) | Average current (mA) | Voltage (V) | Power consumption (mW) | Lifetime of the circuit when measuring and transmitting every 1 s (h) |
| | Before adding the sensor | Current max (mA) | 7.78 | 3.17 | 3.3 | 25.67 | 287 | | Current min (mA) | 2.5 | 3.3 | 8.25 | | After adding the sensor | Current max (mA) | 147.83 | 32.68 | 3.3 | 487.83 | 27 | | Current min (mA) | 8 | 3.3 | 26.4 |
