Introduction

The SparkFun Digital Temperature Sensor Breakout - AS6212 (Qwiic) provides a combination of high temperature accuracy with excellent low power consumption using the AS6212 digital temperature sensor from ams AG. The AS6212 measures temperature with ±0.2°C accuracy between -10°C to 65°C (full measurement range is -40°C to 125°C), consumes an average of 6µA (0.1µA in standby) and communicates over I2C so naturally we put it on a Qwiic breakout to add to our ever expanding Qwiic system. All of this in a tiny IC package measuring 1.5mm x 1mm.
