HTS221 Description
HTS221 is in the process of being terminated and is not remended for new design. The candidate replacement is SHT40-AD1B from Sensirion. A deep-dive transition guide, technical note TN1426, is available on .st., providing a high-level reference to guide the user in replacing STMicroelectronics HTS221 sensor with the SHT4x sensor family from Sensirion as a high-quality alternative.
