STMicroelectronics HTS221 Humidity & Temperature Sensor, ±3.5% RH, ±0.5°C, I²C, LGA-6

STMicroelectronics HTS221 Humidity & Temperature Sensor (LGA-6) is an ultra-compact digital sensor designed for precise environmental monitoring. It integrates a polymer capacitive sensing element with a mixed-signal ASIC to deliver accurate humidity and temperature data via I²C/SPI interfaces.

With factory calibration, low power consumption, and high sensitivity, it ensures reliable performance across industrial and consumer applications. The sensor operates over a wide temperature range and supports selectable output data rates. Its tiny HLGA package makes it ideal for space-constrained designs such as wearables and smart devices.
