Overview

The Embedded Bathroom Control System is a small system based on a 68HC11 and designed to:

• Control the bathroom fan,
• Control the light,
• Control the radio (ie, music),
• Display the temperature, humidity, ...

This system has several hardware components:

• A 68hc11 board with 32Kb of ROM and 32Kb of RAM. This board runs the EBCS software.
• An LCD board which provides a 2x16 LCD display with 4 buttons.
• A Power Control board which has a transformer and 2 triacs (one for fan and one for light).
• A Sensor module which provides temperature, humidity and presence detection.
• A I/O board connected to the CPU board. This is the interface with the sensors, the power control board and the LCD panel.
