  • Page 19: Battery Lifetime (Battery Gateway)

    Lansen manual for Lansen WM-BUS B4 GW (MQTT) Rev: K Date: 2024-04-10 Battery lifetime (Battery Gateway) Since the battery driven gateway has a large super capacitor to assist the battery, it is hard to measure the true battery voltage to determine the service life left on the device. One method to determine the lifetime to get an early warning is by using calculations based on how long the device has spent in the different modes as defined in chapter Power consumption.
  • Page 20 Lansen manual for Lansen WM-BUS B4 GW (MQTT) Rev: K Date: 2024-04-10 Modem active power consumption Total time is already in seconds so we can calculate the total power consumption immediately since the power consumption when a radio is active is 160 mA, according to chapter Power consumption.
