The thermometer shown here is “micro” not only because it is built around the ATtiny13 microcontroller, but also because it can be built as a miniature device when built from SMD components. The temperature is measured by a DS18S20 high precision 1-Wire® digital thermometer from Maxim. The program inside the ATtiny13A microcontroller initiates a single temperature conversion, waits until the conversion has finished, then reads and displays the result. the temperature can be read by counting red and green blinks from a two-colour LED.
