SparkFun Digital Temperature Sensor Breakout - AS6212 (Qwiic)

The SparkFun Qwiic Digital Temperature Sensor Breakout is a high-performance device equipped with the AS6212 digital temperature sensor from ams AG. This sensor offers high temperature accuracy up to ±0.2°C within a broad range from -40°C to +125°C. The device is also designed for energy efficiency, consuming an average of 6µA during operation and only 0.1µA in standby mode. The sensor communicates using I²C and offers eight I²C addresses selectable via solder jumpers on the board. The I²C interface is connected to a pair of Qwiic connectors, compatible with the Qwiic Ecosystem, as well as to a standard 2.54mm-spaced PTH header for those who prefer a soldered connection.

The AS6212 sensor comes with an alert output that can be triggered when the recorded temperature data crosses user-set thresholds. This feature is ideal for monitoring systems that need to maintain a specific temperature range. The sensor's sleep mode, combined with a single-shot temperature measurement function, allows the device to wake up, take a reading, and return to sleep mode. This low-power mode is particularly useful for battery-powered temperature measurement projects.

As part of the SparkFun Qwiic Connect System, this sensor is part of an ecosystem of I²C sensors, actuators, shields, and cables designed to make prototyping faster and less error-prone. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector, reducing the amount of required PCB space and ensuring error-free connections thanks to the polarized design.
