Multi-Parameter Sensing - Combines temperature (-40°C to +85°C), humidity (0-100% r.h.), pressure (300-1100 hPa), and gas sensors for comprehensive environmental analysis. Low-Power Operation - Consumes as little as 0.15 µA in sleep mode and 2.1 µA at 1 Hz (humidity/temperature) for battery-powered devices. Dual Interface Support - Features high-speed I²C (3.4 MHz) and SPI (10 MHz) for flexible integration with microcontrollers. Ultra-Compact Design - 3.0x3.0x0.93 mm metal-lid LGA package enables space-saving deployment in wearables and mobile devices. Independent Sensor Control - Disable individual sensors (humidity/pressure/gas) to optimize power usage for specific applications. Product Description
