AVR Thermometer DS1621

This small thermometer board connects directly to the PORTD of the AVR 2313 project board. It uses the Dallas DS1621 digital thermometer and thermostat chip. The DS1621 measures temperatures from -55°C to +125°C in 0.5°C steps and requires no calibration or external components. It also has a built-in thermostat with high and low setpoints that can be programmed by the user. Below you can see the pin description of the DS1621.
