Battery lasts
Optimised for energy saving
- 99% of the time in sleep mode – SENSECOM is in sleep mode most of the time and thus consumes a negligible amount of power, about one digit of uA.
- Transmission and measurement/readings – more significant consumption occurs when the device is performing some activity (e.g. measurement) and especially when it is transmitting, consuming about 200-350mA in NB-IoT for 0.3 seconds.
- Sending messages – a message is sent either at regular intervals or immediately based on a signal from the sensor (alarm).
- Message reception – waiting for a return transmission (downlink) is done after the transmission and can be reduced or skipped before going to sleep mode.
Years without battery replacement
Minimizing power consumption – the development of each device emphasizes minimal battery consumption and future maintenance. The device can typically operate for up to 15 years without battery replacement depending on:
- the number of transmissions per day (and their varying length depending on the data volume for NB-IoT)
- the type of sensors and their own power consumption
- the frequency of measurement and its duration
Further consumption savings options:
- Consumption can be very well compensated by aggregating measurements into fewer transmissions (e.g., sending one day’s worth of data from hourly measurements) if this latency in sending data does not play a role for the purpose. Alarms are sent immediately (override aggregation).
- Many types of devices allow to filter out unchanged values and reduce the number of transmissions.
