Smart Voice-Controlled Clotheshorse with Connectivity

Overview

This smart clotheshorse system provides multiple control options, including voice control, Wi-Fi, Bluetooth® Low Energy (LE), and touch button control. The design features AC/DC circuitry, a buck regulator, and an LED driver to power the MCU, LED, and other peripheral modules. It also integrates N-channel MOSFETs and half-bridge drivers, providing a comprehensive and efficient approach to modern laundry drying management.

System Benefits​:

  • Supports voice recognition, Wi-Fi, and Bluetooth LE for versatile and convenient operation.
  • Utilizes a 100MHz Arm® Cortex®-M33 with capacitive touch sensing unit (CTSU) and voice recognition firmware.
  • High-performance power devices ensure efficient power and LED control.
