SENSHT41-AD1B-R2
Overview
The SHT41-AD1B-R2 is a high-accuracy digital humidity and temperature sensor from Sensirion's fourth-generation SHT4x series. It offers a wide supply voltage range from 1.08V to 3.6V and communicates via a standard I2C interface with a fixed 0x44 address. This sensor is designed for high-volume applications where low power consumption and a compact 1.5mm x 1.5mm DFN footprint are critical.
Why Choose This Part
The SHT41 provides an excellent balance of accuracy and efficiency, featuring a typical relative humidity accuracy of +/-1.8%. Its extremely low power profile, including a measurement current as low as 320uA and a sleep current of 80nA, makes it ideal for energy-harvesting and mobile applications. The wide 1.08V to 3.6V operating range ensures compatibility with modern low-voltage microcontrollers.
Applications
Key Specifications
Getting Started
Interface the sensor via the I2C bus using a pull-up resistor on the SCL and SDA lines. Engineers can use the Sensirion SEK-SHT4x evaluation kit for rapid prototyping with a PC. Software integration is simplified by Sensirion's C and Python drivers available on GitHub.
