Grove Barometer & Temperature Sensor Module, BMP280

The Grove Barometer Sensor (BMP280) is a precision digital module for measuring atmospheric pressure and ambient temperature. It is designed for easy integration into electronic projects via the standard Grove connector system, eliminating the need for soldering or complex wiring. The module is ideal for weather stations, altitude tracking, and environmental monitoring applications.

This sensor utilises the advanced BMP280 chip from Bosch, providing highly accurate readings. The barometric pressure measurement range is from 300 to 1100 hPa with an accuracy of ±1.0 hPa. Simultaneously, it measures temperature from -40°C to 85°C, enabling comprehensive environmental data collection.

Key Features and Benefits

• Plug-and-Play Simplicity: The Grove interface allows for quick connection to a wide range of microcontroller base boards, such as those from Arduino and Raspberry Pi, speeding up prototyping and development.
• Dual Interface Support: The module supports both I2C and SPI digital communication protocols, offering flexibility for different project requirements and microcontroller pin allocations.
• Low Power Operation: With a current consumption of just 0.6mA, it is highly efficient and suitable for battery-powered or portable devices.
• Dual Voltage Compatibility: It can be powered by either 3.3V or 5V DC supplies, ensuring compatibility with most common development platforms.
• Compact and Lightweight: The small footprint (20mm x 40mm) and minimal weight (3g) make it perfect for space-constrained projects.

Typical Applications

This sensor is commonly used in creating personal weather stations, indoor climate monitors, and altitude measurement devices for drones or hiking gadgets. It is also valuable in projects involving weather forecasting, home automation for HVAC control, and IoT devices that require environmental context.
