Behind the Scenes
The largest organ of the human body is the skin and it is most readily affected by
temperature. Little wonder then that so much effort is put into environmental control
systems (heating and air conditioning).
This
thermometer/thermostat chip. This chip measures temperature and makes it
available to the BASIC Stamp through a synchronous serial interface. The DS1620 is
