Abstract

A low-power electronic pipette has a charging management module (10), a control module (20), a motor driving module (30), a display module (40), a communication module (50), a sensing module (60), and a battery module (70). The charging management module, the communication module, and the sensing module are each in two-way communication with the control module. The display module and the motor driving module are each in one-way communication with the control module. The battery module supplies energy to the low-power electronic pipette. When the sensing module acquires a signal and determines that the low-power electronic pipette has not been operated for a predetermined period and is not in a charging state, the low-power electronic pipette enters a low-power mode, in which the control module turns off the charging management module, the motor driving module, the display module, and the communication module, and the control module enters a sleep state.
