Thermocouples provide a low-cost, reliable means of measuring temperature over a wide range. The challenge when using a thermocouple is accurately measuring the very low Seebeck output voltage (fractional to low millivolts) from the element, and providing for cold junction temperature compensation.
The Dallas/Maxim DS2760 High Precision Li+ Battery Monitor is very easily configured into an effective thermocouple interface. The Parallax DS2760 Thermocouple Module capitalizes on this application and provides a complete connection between BS2p BASIC Stamp microcontroller and a standard thermocouple element.

- 1-Wire interface allows multiple devices with just one BASIC Stamp I/O pin
- Cold Junction measurement: 0 to +127 °C (0.125 °C resolution)
- Low power consumption: Active current = 90 µA max, Sleep current: 2 µA max
Key Specifications:
- Power Requirements: 2.5 V to 5.5 V @ 90 µA (max)
- Communication: Dallas 1-Wire® Interface with unique 64-bit device address
- Dimensions: 1.08 x 0.43 x 0.3 in (27.5 x 11 x 7 mm)
- Operating Temperature: -4 to +158 °F (-20°C to +70°C)
Kit Contents:
- Thermocouple Module
- K-Type (Chromel/Alumel) Element Temperature Range: +32 to +1873 °F (0 to +1023 °C)
