Adafruit Sensirion SHT45 Precision Temperature & Humidity Sensor

Sensirion Temperature/Humidity sensors are renowned for their precision and reliability. Introducing the SHT45, the pinnacle of this line, offering exceptional ±1.0% relative humidity accuracy between 25 to 75% and ±0.1°C temperature accuracy from 0 to 75°C. This sensor is equipped with a true I2C interface that ensures seamless integration with just two wires besides power and ground, simplifying connections significantly.

Specifications include 3V or 5V compliance, enabled by an onboard voltage regulator and level shifting circuitry. The SHT45 comes on a breakout board with added pull-up resistors and capacitors, along with SparkFun Qwiic compatible STEMMA QT connectors for effortless I2C bus connections, eliminating the need for soldering. If you opt for breadboard experimentation, the package includes a fully assembled, tested PCB breakout and a header piece requiring simple soldering.

The accompanying Arduino and CircuitPython/Python libraries ensure compatibility with a range of microcontrollers and single-board computers like the Raspberry Pi. This makes the SHT45 a versatile choice for integrating highly accurate environmental sensing into your projects.
