Abstract

The invention discloses a tropical fish tank temperature controller and belongs to the field of electronic monitoring and control. The tropical fish tank temperature controller comprises a power switch used for power supply, a power supply module, an analog / digital (A / D) converter, a single chip microcomputer control circuit, a relay and a temperature controller, an electric heater (1) and a separation net (2) which are arranged in a fish tank. The temperature controller is connected with the signal input end of the single chip microcomputer control circuit through the A / D converter and transmits a collected temperature value to the single chip microcomputer control circuit through the A / D converter. The single chip microcomputer control circuit compares the received temperature value and a preset value and controls the electric heater (1) to work through the relay according to the comparison result, and therefore the tropical fish tank temperature controller achieves the function of controlling temperature of water in the fish tank thermostatically.

Description

technical field [0001] The invention relates to a temperature controller for a tropical fish tank, which belongs to the field of electronic monitoring and alarming. Background technique [0002] In daily life, more and more people like to breed tropical fish, and tropical fish are narrow-temperature fish, which have strict requirements on water temperature and are particularly sensitive to changes in water temperature. Too high or too low water temperature is harmful to most tropical fish. It is said that life is in danger, so how to control the water temperature in the tropical fish tank has become a headache for people. [0003] In order to solve this problem, some aquarium heaters have been proposed, but the current aquarium heaters use discrete element circuits as controllers, which have single functions, cannot be expanded, and have poor constant temperature effects. Contents of the invention [0004] The technical problem to be solved by the present invention is to ...
