This Paper presents a Smoke lampblack machine design based on 51Microprocessor, System have smoke sensors, When smoke-thickness is up to the thresholds, It will Automatically starts the motor, extract the smoke rapidly, when the ray is dark, Automatically starts the lighting, when Smoke lampblack machine and cooker work in long time and nobody is beside, The load infrared sensors module will be send the alarm signals, Besides, Use 1-wire devices DS18B20 test the kitchen temperature, And set a limit on the temperature, when fire hazard or dry cook happen, the current temperature will exceed the limit, the system immediately cut off the air supply and make alarm, Use timer function effectively control the cooking time, five independent key used to set work mode, The system status through liquid crystal 1602 to display.
