This paper is based on the temperature and humidity controller designed and produced by LM324 comparator, which can constantly monitor the environment temperature and finish alarm display and output control in accordance with the established function. The controller is composed of DC voltage regulator module, sensor input module, display output module and temperature and humidity control module. The test of experimental prototypes shows that the temperature and humidity controller based on the LM324 comparator has the advantages of high precision and quick response, etc., which solves problems of complicated structure, high cost and large temperature variations existing in the current temperature and humidity controllers.
