Summary of AT89S52 DS1620 THERMOMETER CIRCUIT (LCD DISPLAY)
This project utilizes an AT89S52 microcontroller and a DS1620 temperature sensor to display ambient temperature on a 128×64 graphic LCD. The system triggers a red LED when the temperature exceeds 25°C and illuminates a green LED when it drops below this threshold. A 12 MHz crystal oscillator provides the necessary clock signal for operation, while the microcontroller processes 9-bit data from the sensor.
Parts used in the AT89S52 DS1620 Thermometer Circuit:
- AT89S52 Microcontroller
- DS1620 Temperature Sensor
- 128 × 64 Graphic LCD
- Red LED
- Green LED
- 12 MHz Crystal Clock Oscillator

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.
