Measuring temperature is not always a trivial task. Most sensors used to
read temperature transduce the reading to an electrical signal. These
sensors provide a voltage level relative to the temperature reading. This
voltage is converted to a digital number using an analog-to-digital
converter where it can then be processed by a microprocessor or
microcontroller.
The DS1620 Digital Thermometer from Dallas Semiconductor provides
a single-chip solution that reads temperature and converts it to a 9-bit
digital value. This data is then read from the DS1620 via a serial
interface to a microcontroller (MCU). The device also provides three
thermal alarm outputs for thermostatic control.
