PIC 18 LCD Digital Thermometer
Designing a Digital Thermometer w/ LM35 — PIC Unit #02 — LCD — Episode #05
Hi, in this project, the design of a digital thermometer is described.
Let’s see the code:
An analog temperature sensor (LM35DZ) is used to sense the temperature, and the temperature is displayed on an LCD:)
The output voltage is given by LM35 is connected to PIC’s channel A/D AN2
RE0: Sensor temperature LM35
Vo = 10 mV/°C Thus, for example, at 20°C, the output voltage is 200 mV, at 25°C it is 250 mV, and so on.
And that’s it!
In the next lesson let’s implement a simple calculator:)
Thanks a lot! See you in the next episode.
Bye!
