Abstract

The invention discloses a temperature and humidity controller, which comprises a temperature sensor, a humidity sensor, a microprocessor unit (MPU), a temperature basic value setter, a humidity basic value setter, a heater control loop and an exhaust fan control loop, wherein the output ends of the temperature sensor and the temperature basic value setter are connected with a temperature control module in the MPU; and the output ends of the humidity sensor and the humidity basic value setter are connected with a humidity control module in the MPU. According to the temperature and humidity controller, environmental temperature and humidity can be detected and regulated in real time so as to be maintained within ideal ranges; and in addition, the operating states of a heater and an exhaust fan can be displayed in real time, so that the operating state of the controller is clear.

Description

technical field [0001] The invention relates to a temperature and humidity controller. Background technique [0002] In order to ensure the temperature and humidity environment requirements of special occasions such as switch cabinets, central cabinets, and wine cellars, heaters are often added in these environments. The controller of the heater controls the heating state of the heater through monitoring the temperature and humidity. But the existing ones usually can only change the temperature and humidity of the environment by heating. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides an intelligent temperature and humidity controller, which can control the heater and exhaust fan in real time according to the ambient temperature and humidity, and can clarify their working status. [0004] Technical solution: In order to solve the above-mentioned technical problems, the tech...
