BME280 Sensor
The BME280 is a highly integrated environmental sensor developed by Bosch Sensortec. It combines temperature, pressure, and humidity sensing in a single compact package, making it ideal for weather monitoring and IoT applications. With support for both I2C and SPI interfaces, the sensor is flexible and easy to integrate into microcontroller-based systems such as STM32, Arduino, ESP8266, and ESP32. Its low power consumption makes it suitable for battery-powered devices, while the high precision ensures reliable performance even in demanding applications.
Key Features:
- Measures temperature, pressure, and humidity in one device
- Supports I2C (up to 3.4 MHz) and SPI (up to 10 MHz) communication
- Wide measurement ranges:
- Temperature: -40 °C to +85 °C
- Pressure: 300 hPa to 1100 hPa
- Humidity: 0% to 100% RH
- High resolution: up to 20-bit for pressure/temperature and 16-bit for humidity
- Very low power consumption, ideal for portable/IoT projects
- Compact package: 2.5 × 2.5 × 0.93 mm
Applications:
- Weather stations and climate monitoring systems
- IoT devices for smart homes and smart cities
- Altitude tracking in drones and navigation devices
- Indoor air quality monitoring
- Wearable devices for health and fitness tracking
- Environmental data logging for research and agriculture
