A neat infrared thermometer with PIC microcontroller

August 22nd, 2010
Here is something I’ve been looking for for a while – a simple and versatile PIC-microcontroller-based voltmeter/amperemeter. Of course, there are many similar projects, but this one fits my requirements best. It is simple to build and not picky when it comes to the need of high-precision resistors, because of an easy calibration routine.
The code is a great starting point for building a more complex project.

PIC-microcontroller based thermometer with recycled Nokia screen

Isn't it cute?
If there is something I love about an electronics project, it is reuse of old parts – be it a modem, or a power supply, or just a clever use of an old device for a project enclosure.
This project hooks a Nokia 3310 LCD to PIC12F629 or PIC12F675 microcontroller and uses a DS18B20 thermal sensor to measure the temperature. The project is completely documented, with list of components, PCB layout, and detailed construction and configuration instructions.
Not only this, but the design is really cute – no enclosure needed, if you ask me. Everything fits behind the LCD. Hey Apple, even the sleekest new iThingy can’t beat that!
