Batterry lasts

Optimised for energy saving

1. 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 unit of uA.
2. 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 50mA in SIGFOX (a few seconds), 200-350mA in NB-IoT (0.3s).
3. Sending messages – a message is sent either at regular intervals or immediately based on a signal from the sensor (alarm).
4. 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 

Consumption can be very well compensated for in NB-IoT by aggregating content 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.
