The Adafruit MS8607 is a factory-calibrated 3-in-1 sensor that measures barometric pressure, relative humidity, and temperature over I2C. Made by TE Connectivity, this PHT (Pressure, Humidity, Temperature) sensor is a compact, all-in-one solution for weather stations, environmental monitoring, and climate-controlled enclosures.

With extremely low power consumption (as low as 0.78 µA), the MS8607 is well-suited for battery-powered sensing projects. The breakout includes a 3.3 V regulator and level shifting for compatibility with both 3.3 V and 5 V systems, plus STEMMA QT / Qwiic connectors for solderless I2C wiring.
