An internal battery powers the RFID Active Tag. The Active Tag(HT-05) will transmit a RF(Radio Frequency) tag ID data at a pre-set time-interval when power is on. The lifespan of the Active Tag
ends when the battery life is exhausted. The Average current consumption is 45uA when the time-interval is 2 seconds and VCC is 3.3V. Before the battery is exhausted, there will be a low voltage
detection and warning signal.
