This is a breakout board for the incredibly small TMP102 digital temperature sensor. The TMP102 is a digital sensor (I2C a.k.a. TWI), has a resolution of 0.0625°C, and is accurate up to 0.5°C. The sensor requires very low-current, and is loaded with features.

Communication with the TMP102 is achieved through a two-wire serial interface. There is no on-board voltage regulator, so supplied voltage should be between 1.4 to 3.6VDC. Filtering capacitors and pull-up resistors are included as shown.

Features:

• 12-bit, 0.0625°C resolution
• Accuracy: 0.5°C (-25°C to +85°C)
• Low quiescent current
• 10µA Active (max)
• 1µA Shutdown (max)
• 1.4V to 3.6VDC supply range
• Two-wire serial interface
