digital thermometer with arduino uno

In this article we make digital thermometer on the Arduino Uno. In this Digital Thermometer temperature sensor used is LM35DZ. In other applications you can replace with LM35 temperature sensor such as DS18B20 and others. In principle, the sensor will detect the temperature, then go to the ADC (analog to digital converter) on the arduino Uno and

processed, and then displayed on the LCD. In this digital thermometer LCD used is Hitachi HD44780 chip. Liquid crystal displays (LCDs) offer a convenient and inexpensive way to provide a user interface for a project. Here is a picture digital thermometer: In this circuit the output port LM35DZ temperature sensor, connected to the ADC analog port A0 on arduino uno. LCD display digital thermometer, digital port pin of the LCD to the Arduino Uno is: In this piece of coding digital thermometer you can do to change the calibration value. In this experiment we include the value of 8. 6. You can change the value to 9 or 10. You will find the difference. Our advice to perform the calibration, after changing the settings on coding the value of digital thermometer, do the comparison with a digital thermometer on the market. You can download a digital thermometer coding below. For password is: circuitdiagram- schematic. com. And Good luck . !
