Description: lm35 is a temperature sensor, 1 degree per liter, corresponding to the voltage on the rise 10mV (which is the device' s characteristics) per liter, 0.5 degrees of the function required, the voltage rise 5mV, and the temperature is displayed in the lcd1602 on the A/D conversion resolution of b to 0.005v, which is the temperature sensor every 0.5 degrees, ADC0804 to convert a (voltage-> temperature) go here also show that the temperature detected by ds1802 lm35 temperature and voltage from comparing (in the same ambient temperature should be equal) resolution b = 5mV = VREF/256 so VREF = 1.28V and also because the 9-pin ADC0802 There is an amplifier (to enlarge the original 2-fold) so the input voltage Vx 9 pin = VREF/2 = 1.28/2 = 0.64V (by potentiometer to control)
