A remote control circuit for air-conditioned clothing

Abstract

This invention discloses a remote control circuit for an air-conditioned garment, including a battery, a main control MCU, and a wireless transmitter chip. The wireless transmitter chip is connected to the main control MCU, which is connected to buttons. The wireless transmitter chip is also connected to an antenna. The buttons include an on / off button, an output voltage increase button, and an output voltage decrease button, each connected to the main control MCU. The antenna is connected to the wireless transmitter chip via an LC oscillation circuit, and the wireless transmitter chip is also connected to a filter circuit and a crystal oscillator. This invention enables long-distance, contactless operation of the air-conditioned garment, including power on / off and speed adjustment, eliminating the limitations of wired control methods and making it more convenient to use. Furthermore, the entire remote control circuit has a very simple structure, consisting of only the MCU and the wireless transmitter chip, and the accompanying peripheral circuitry is also simple, significantly reducing the cost of the remote control and the design complexity of the circuit.
