Introducing the most sophisticated temperature sensor - the AS622

The AS6221 is an ultra small high precision digital temperature sensor, ideal for a wide range of products, from the smallest critical healthcare applications to lifestyle monitoring wearables.

The AS6221 boasts the highest precision reading accuracy of up to ±0.09°C, making it ideal for medical monitoring devices. Due to its powerful accuracy, including the AS6221 in various applications can assist in achieving medical certification (EN 12470-3). The AS26221 is also compatible with many different system designs, the short thermal connection and a reduced thermal capacity PCB provides optimal results and the ability to monitor the temperature of air, body, skin and other vectors.

Measuring only 1.5mm x 1.0mm, its compact size allows the AS6221 to be fitted into extremely small devices. The highly integrated digital sensor system requires no calibration or linearization and provides measurement output via a standard I²C interface; it supports eight I²C addresses, avoiding bus conflicts in multi-sensor use cases. Thus, making it highly compatible with everyday wearables such as smart watches and mobile phones.
