The Sensirion SHT45 Temperature and Humidity Sensor is a high-accuracy, next-generation sensor designed for easy interfacing with I2C communication. This fourth-generation sensor provides excellent accuracy with ±1.0% relative humidity from 25 to 75% and ±0.1°C temperature accuracy from 0 to 75°C.
Key features:
-
True I2C Interface: Simplifies communication using only two wires (plus power and ground), making it easy to integrate with any microcontroller or microcomputer.
-
3V or 5V Compatible: The breakout board supports both voltage levels, so it can work with a wide range of systems.
-
Breakout Board Design: Includes pull-up resistors and capacitors for easy setup.
-
STEMMA QT Connector: Features a SparkFun Qwiic compatible connector for simple plug-and-play I2C integration, eliminating the need for soldering.
-
Easy Setup: The breakout board comes fully assembled and tested with a small piece of header included. A few minutes of soldering are required to attach the header to the board.
-
Library Support: Arduino and CircuitPython/Python libraries are available for quick and easy integration with most microcontrollers and single-board computers, like Raspberry Pi.
This sensor is perfect for projects that require precise temperature and humidity measurements, and with its simple I2C interface, it’s ideal for both beginners and advanced developers.
