Description

The SHT41I-AD1B-R2 from Sensirion is a premium industrial humidity and temperature sensor built on the company’s proven CMOSens® technology. It combines a capacitive polymer sensing element for humidity with a band-gap temperature sensor, delivering calibrated digital I2C signals and simultaneous analog voltage outputs for both parameters. This dual-output capability provides flexibility for direct analog-to-digital conversion or straightforward digital communication with microcontrollers like Arduino, Raspberry Pi, ESP32, and STM32.

Engineered for harsh environments, the sensor features robust ESD protection (2 kV HBM) and can withstand supply voltages up to 6V. Its fast response and excellent long-term stability make it ideal for demanding applications requiring precise and reliable environmental data logging, process control, and compliance monitoring.

Key Features

  • High-accuracy sensing with ±1.5% RH and ±0.3°C typical performance.
  • Dual-output interface: digital I2C and calibrated analog voltage (40 mV/%RH, 23 mV/°C).
  • Extended operating temperature from -40°C to +125°C for industrial use.
  • Ultra-low power consumption with an average current of 80 nA.
  • Robust design with integrated ESD protection for enhanced reliability.
  • Fully calibrated and NIST-traceable, ensuring measurement integrity.
  • Fast response times enable real-time monitoring and control.
  • Compact SMD package (2.0 x 2.0 x 0.8 mm) for space-constrained designs.

Applications

  • Industrial process monitoring and control systems
  • HVAC and building automation for climate control
  • Precision agriculture and greenhouse environmental monitoring
  • Medical device and pharmaceutical storage compliance
  • Data center and server rack thermal management
