| Summary: | The project is purposely to ease user especially old people to switch on or off automatically and for safety from fire accident. Temperature sensors will detect vicinity temperature and PIC will measure the temperature. It will display the measured value on LCD. The PIC is interface with NPN power transistors to on or off the fans. If temperature sensor A detects temperature which higher than trigger value, and temperature sensor B detects temperature lower than trigger value, LED A and fan A will on while LED B, fan B and buzzer are off. If the temperature sensor A detects temperature lower than trigger value and the temperature sensor B detects temperature higher than trigger value, the LED B and fan B will on while the LED A, fan A and the buzzer are off. If the temperature sensor A detects temperature higher than trigger value and the temperature sensor B detects temperature higher than trigger value, both the LEDs and fans including the buzzer will on and vice versa. Another green LED is function as a power indicator. |
