This project gave ds1620’n given as a result of the digitally using AT89S52 microcontroller is a graphic display of temperature information of the LCD screen.
Moreover, the circuit ambient temperature when it reaches a temperature above 250C is no longer a red LED lighting in the same way as the ambient temperature drops below 250C, a green LED lights up to notify user intended. 12 MHz crystal clock oscillator circuit to set the clock oscillator is used.
DS1620 is a temperature sensor and also the legs 8 is used as thermostat. Temperature is given as 9-bit data.
Demonstration of circuit temperature is obtained by using a 128 × 64 graphic LCD. LCD’s D0, D1, D2, D3, D4, D5, D6, D7 is provided with a connection to microcontrollers. Second intervals in the program I set the LCD also seems my school ID.
