Building a modular infrared thermometer

Brian McEvoy has created a slick Arduino-based modular infrared thermometer.

According to McEvoy, ESPeri.IRBud allows users to “associate an audible tone with a temperature from an infrared, contactless thermometer.”

Key project components include:

Arduino Pro Mini (ATmega168)

USB FTDI interface adapter

Melexis thermometer

4.7K pull-up resistors

Cord from a stereo headphone with microphone

3.5mm…
