The TRP-3-4 module is powered by a lithium battery 3.6V 2.4Ah. The consumption of the module TRP is very low, generally less than 10 μA. The radio transmission consumes more energy but only during some milliseconds.

With the lithium battery, the autonomy can reach 5, 10 even 15 years, according to the selected settings.

The battery is replaceable.

By default, the interval of measure of the TRP-3-4 is 15 minutes. The interval of measure can be modified by the serial interface with the appropriate software.
