Figure 3-2. Remote Sensor Transceiver Board
The current consumption profile over time is shown in Figure 3-3 . During the temperature measurement
period of 40ms, the LED is switched on in parallel, increasing current consumption. Figure 3-3 shows
current consumption for the measurement period with and without LED. The RF telegram transmission
takes about 11ms at a power level of 6dBm, resulting in current consumption of about 9.4mA. In OFF
mode the temperature sensor is switched off and the resulting current is indicated by the Atmel ATA8510
transceiver and the CMM-1923 RTC current consumption. This OFF mode current is highly dependent on
ambient temperature shown in the datasheets [1] and [3].
Figure 3-3 indicates current consumption
measured at a room temperature of 24°C.
