Aromatherapy beauty steam bath room should have the following functions:
①Shower function, including overhead and side spray; ②Surfing bath; ③Foot massage; ④Aromatherapy beauty; ⑤Steam sauna; ⑥Perpetual calendar; ⑦Chinese screen display; ⑧Fault self-check function; ⑨Automatic detection and adjustment of temperature and humidity; ⑩Built-in three classic light music, such as To Alice, Jasmine, My Heart Will Go On, etc. This article uses Microchip's PIC16F877 microcontroller as the main controller, and discusses in detail how to realize the intelligent control of the aromatherapy beauty steam bath room from both software and hardware aspects.
Hardware Design
The PlC16F877 microcontroller is the most widely used FLASH CPU of Microchip. It contains 8K FLASH program storage area, 368 bytes of RAM, 256 bytes of EEPROM, 35 independently usable I/O ports, a 16-bit counter/timer, two 8-bit counter/timers, 14 interrupt sources that can be used independently or nested, 2 capture/comparator/PWM modules, 8-channel 10-bit A/D, watchdog WDT and power monitoring module, with multiple power saving modes such as sleep and wait, and the I/O port can directly drive the LCD.
