Description

technical field [0001] The invention belongs to the field of temperature measurement, and is a device for detecting, recording and controlling water temperature, more specifically, an automatic constant temperature controller for swimming pools. Background technique [0002] At present, in some temperature control system circuits, it is widely used to pass through the corresponding signal adjustment circuit through the thermocouple, thermal resistance or PN junction temperature measurement circuit, convert it into a receivable analog quantity through the thermoelectric conversion device, and then pass the sample / hold The circuit performs A / D conversion, and finally sends it to the microcontroller and its corresponding peripheral circuits for corresponding operations to complete temperature control. However, the traditional signal adjustment circuit is complicated to implement, susceptible to interference, difficult to control and low in precision. In practical applications,...
