LOW POWER CONSUMPTION POWER MODULE AND CONTROL SCHEME SUPPORTING MULTIPLE VOLTAGE IN SENSOR NETWORK

摘要

A low-power source module for supporting multiple voltages in a sensor network and a method for controlling the same are provided to operate a multi-voltage sensor mode effectively, which uses a power source having a limited capacity in a sensor network system, by operating various elements having their respective voltages through voltage regulators by means of a power source having a single voltage. A low-power source module for supporting multiple voltages in a sensor network consists of a power source(1), an MCU(2), and a sensor part(X). The power source, connected to the back of the power source, is operated by the power supplied from the power source. The sensor part, connected to the MCU, comprises software control switches(5), voltage regulators(3), and sensors(4). The software control switches, connected to the back of the MCU and installed in parallel, calculate sensor operation standby time by the MCU's internal timer. The voltage regulators, respectively connected with the software control switches, perform voltage regulation. Each of the sensors, driven by a voltage regulated through each of the voltage regulators, delivers a signal to the MCU.
