Key Features
Temperature: Measures 0°C–65°C (operational range -40°C–85°C) with ±0.5°C typical error and 0.1°C resolution, self-corrected via temperature compensation for humidity and pressure.
Humidity: Senses 0%–100%RH with ±2% accuracy, 0.8% resolution, and fast >1s response time, ideal for real-time air quality monitoring.
Atmospheric Pressure: Detects 300–1100hPa with ±1hPa accuracy and 0.18Pa resolution, enabling use as an altimeter with ±1m altitude precision.
Dual Interfaces: Supports I2C (standard/fast/fast+ modes) and SPI (3/4-wire) for seamless integration with Arduino, ESP32, and Raspberry Pi.
Address Configuration: I2C slave address set via SD0 pin (0x76 default, 0x77 when high), avoiding conflicts in multi-sensor setups.
Energy-Efficient Modes: Minimal current draw for extended battery life: 1.8μA (humidity/temperature), 2.8μA (pressure/temperature), 3.6μA (all sensors) at 1Hz sampling; 0.1μA in sleep mode.
Wide Voltage Range: 1.71V–3.6V (VDD main supply), 1.2V–3.6V (VDDIO interface), compatible with 3.3V/5V systems.
Compact Breakout Board: 7-pin 2.54mm header, two 3.5mm mounting holes, and solder jumpers (GS1/GS2) for power rail and protocol selection.
On-Board Components: 10kΩ I2C pull-up resistors, 0.1μF decoupling capacitors, and metal-lid LGA package for noise immunity and durability.
