It is an automatic power off circuit diagram.If you need to shut-off any electronic device after a set amount of time then this circuit can do that automatically; when you are even sleeping! For example this auto power off circuit can be used with garden/porch light, soldering iron/ glue gun or similar other devices to auto shut it off for saving electricity or save the device, or you can use. Basically the circuit switches ON a toy motor fan connected to the motor driver whenever heat is applied to the temperature sensor unit using say a burning matchstick. The wind from the motor fan would blow off the matchstick and switches OFF itself automatically. Here the Temperature is the output to be controlled In our case fanSpeed will have a value of 32 at tempMin and 255 at tempMax. These values are used to control the speed of the fan using PWM and the analogWrite(). The fanLCD re-maps the temp to allow the display of fanSpeed in a 0 to 100% range so you can say that the speed of the fan is directly dependent of the LM35's temperature. When the temperature reaches the value set in tempMax the fan will be at its maximum spinning velocity and the LCD will display FANS: 100% even though the.
