The SparkFun AS6212 Digital Temperature Sensor Breakout delivers high-accuracy temperature measurements with excellent low power consumption. Using the AS6212 sensor from ams AG, it achieves ±0.2 °C accuracy across a wide range and consumes just 6 µA in normal operation.

The breakout communicates via I2C with eight selectable addresses and includes a pair of Qwiic connectors for plug-and-play integration. A standard 0.1"-spaced PTH header is also provided for soldered connections.

Key Features

• High Accuracy – ±0.2 °C from −10 °C to 65 °C, ±0.3 °C to −40 °C/85 °C, ±0.5 °C across the full range
• Ultra-Low Power – 6 µA typical consumption, 0.1 µA in standby mode
• I2C Interface – Eight selectable addresses (0x48 default) via solder jumpers
• Alert Output – Configurable high/low temperature thresholds for system monitoring
• Single-Shot Mode – Wake from sleep, take one reading, and return to sleep for battery-powered applications
• Qwiic Compatible – Two Qwiic connectors for daisy-chaining, plus 0.1" PTH header
• Wide Voltage Range – 1.7 V to 3.6 V operating voltage
• Operating Temperature – −10 °C to 125 °C
