BME280 Environmental Sensor: Temperature, Humidity, and Barometric Pressure
Overview
The BME280 Environmental Sensor is a compact device designed to measure environmental parameters such as temperature, humidity, and barometric pressure. It features both I2C and SPI communication interfaces and operates effectively at voltage levels of 3.3V or 5V. Its small size combined with low power consumption makes it ideal for various applications including environmental monitoring, weather forecasting, altimetry, and Internet of Things (IoT) projects.
Key Features
- Dual Communication Interfaces: Supports I2C (default) with configurable slave address; can switch to SPI mode via I/O settings.
- Voltage Compatibility: Equipped with an onboard voltage level translator for seamless operation at both 3.3V and 5V.
- Comprehensive Development Resources: Includes manuals and examples tailored for platforms like Raspberry Pi, Arduino, and STM32.
Technical Specifications
- Operating Voltage: Compatible with both 3.3V and 5V systems.
- Communication Protocols: Utilizes I2C/SPI interfaces for data transmission.
- Temperature Measurement Range: -40°C to +85°C; resolution of 0.01°C; accuracy within ±1°C.
- Humidity Measurement Range: From 0% to 100% RH; resolution of 0.008% RH; accuracy within ±3% RH with a response time of approximately one second.
- Barometric Pressure Measurement Range: Measures from 300 hPa to 1100 hPa; resolution of approximately 0.18 Pa; accuracy within ±1 hPa.
- Power Consumption: Extremely low at less than 0.1 mA when sampling at a frequency of one Hertz (for humidity, pressure, temperature).
- Dimensions: Compact size measuring just 27mm x 20mm.
- Mounting Hole Size: Designed for easy installation with mounting holes sized at Ø2mm.
