Title:
LOW-POWER-CONSUMPTION HYGROTHERMOGRAPH CIRCUIT STRUCTURE AND MEASUREMENT CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/227605
Kind Code:
A1
Abstract:
A low-power-consumption hygrothermograph circuit structure. The circuit structure comprises: a micro-control unit, a register module and a clock module. The micro-control unit is connected to an external software module and is used to configure the register module. The register module is connected to the micro-control unit and is used to measure temperature and humidity by means of changes to an internal state machine of the register module. The clock module is connected to the register module and is used to provide a clock source signal for the register module. The present invention further relates to a corresponding measurement control method. In the circuit structure and the measurement control method therefor, the problem of measurement precision caused by a system framework is avoided by mean of a hardware mode. Compared to a software mode, since the hardware mode is not affected by the working frequency of the system, the reliability is thus higher; and the power consumption of the system is further reduced, thereby having high practicality.
