Board Mount Humidity Sensors Intermediate Humidity and Temperature Sensor
Humidity, Temperature 0 ~ 100% RH I2C ±1.8% RH 4 s Surface Mount
The SHT41-AD1B-R2 is a fully calibrated, low-power environmental sensor that measures relative humidity (RH) and temperature. It integrates sensing elements, signal processing, and a digital interface into a small surface-mount package, making it ideal for space-constrained designs.
Key Features
Sensor Type: Digital humidity and temperature sensor
Interface: I²C (easy MCU integration)
Supply Voltage: ~1.08 V to 3.6 V
Humidity Accuracy: up to ±1.8% RH (typical)
Temperature Accuracy: up to ±0.2 °C (typical)
Response Time: Fast measurement and low latency
Power Consumption: Ultra-low, suitable for battery devices
Package: DFN (compact, ~1.5 × 1.5 mm)
Factory Calibration: No external calibration required
Functional Overview
