Embodiment

[0033] Embodiment: the structure of the present invention is as figure 1 As shown, it mainly includes a power supply unit, a temperature and humidity detection unit, a central controller, a clock unit, an output control unit, a key unit and a display unit.

[0034] The power supply unit provides control power for the entire controller. In this embodiment, DC5V is used as the power supply unit to provide power supply for the entire controller, and is connected to the central controller through wires.

[0035] The temperature and humidity detection unit is used for ambient temperature and humidity detection. It uses a DHT21 sensor, which includes a capacitive humidity sensing element and an NTC temperature measuring element. It is connected to the central controller through wires, and its output is a discrete number. It can be directly used in digital systems. The sensor adopts single-bus communication mode, and it only needs to be connected to one pin of the central controller...

Abstract

The invention discloses an intelligent electric fan controller based on a single chip microcomputer, which comprises a central controller, a power supply unit and a display unit. The power supply unit, the display unit, a push-button unit, a clock unit, a temperature detecting unit and an output control unit are respectively connected with the central controller through leads. The problems that a common electric fan can perform gear adjustment only in a manual mode and cannot automatically perform free shifting according to environmental temperature and humidity, and the like.

Description

technical field [0001] The invention relates to electric fan control technology, in particular to a single-chip microcomputer-based electric fan control technology. Background technique [0002] At present, the commonly used electric fan control is to use the gear control switch on the electric fan body to adjust manually. This manual control method has many disadvantages. If manual adjustment is required, it is inconvenient to use, and it cannot be adjusted automatically according to the ambient temperature and humidity. Switching, etc. Once the gear is manually selected, the electric fan will always run in this gear, and the electric fan will not automatically stop and close when the person leaves, which is not conducive to energy saving and environmental protection. Contents of the invention [0003] The technical problem to be solved in the present invention: [0004] An intelligent electric fan controller based on a single-chip microcomputer is provided to solve the ...
