Adafruit Sensirion SHT41 Temperature & Humidity Sensor

Sensirion's SHT41 sensor is a top-tier choice for precision temperature and humidity measurements, boasting a typical relative humidity accuracy of ±1.8% from 25 to 75% and ±0.2°C accuracy from 0 to 75°C.

Unlike its SHT40 predecessor, the SHT41 delivers enhanced accuracy across the complete humidity range, with a typical accuracy of ±2% over 0-100% RH. This improvement ensures reliability in diverse environments.

The sensor features a true I2C interface for seamless communication, requiring only two wires for data transfer. It's compatible with 3V or 5V systems, allowing integration with any microcontroller or microcomputer. A voltage regulator and level-shifting circuitry boost its versatility.

Our breakout board includes the SHT41 and necessary circuitry, like pullup resistors and capacitors, along with SparkFun Qwiic-compatible STEMMA QT connectors for effortless, solder-free connections. A fully assembled PCB and header piece are included, streamlining setup for breadboard use.

Comprehensive software support is offered with Arduino and CircuitPython/Python libraries, ensuring compatibility with microcontrollers or single-board computers, such as the Raspberry Pi.
