About this item

The Adafruit HTS221 Temperature & Humidity Sensor Breakout Board provides precise environmental measurements in a compact design. It measures relative humidity from 0% to 100% with ±3.5% accuracy and temperature from -40°C to 120°C with ±0.5°C accuracy. The sensor uses capacitive technology for humidity and has a high-resolution temperature sensor. Operating at 3V to 5V, it supports both I²C and SPI communication protocols. Featuring a STEMMA QT / Qwiic connector, it allows easy, solderless integration with platforms like Arduino and Raspberry Pi. Ideal for weather stations, HVAC, and indoor air quality monitoring projects.
