BME280 Temperature, Humidity, Pressure Sensor – Environmental Sensors
The BME280 is a compact, high‑precision sensor that simultaneously measures temperature, relative humidity, and barometric pressure. Engineered by Bosch Sensortec, it combines three essential environmental metrics into a single, low‑power module that plugs directly into Arduino, Raspberry Pi, ESP32, and other classroom‑ready micro‑controller boards. Its rugged, solder‑ready footprint makes it ideal for labs, maker‑spaces, and outdoor field kits, letting students capture real‑world data with professional‑grade accuracy.
With this sensor, students explore the science behind weather patterns, climate change, and human comfort zones. They learn to program I²C and SPI interfaces, calibrate raw data, perform data‑logging, and visualize trends using Python, MATLAB, or spreadsheet tools. By integrating the BME280 into projects such as a smart greenhouse monitor, a wearable climate tracker, or a weather‑station network, learners practice the full STEAM cycle: hypothesize, experiment, analyze, and iterate.
Key Features
- Triple‑sensor (‑40 °C to 85 °C, 0‑100 % RH, 300‑1100 hPa) with ±1 °C, ±3 % RH, ±1 hPa accuracy
- Ultra‑low power (0.1 mA in sleep mode) for battery‑operated experiments
- I²C and SPI communication for flexible integration
- Small 2.5 × 2.5 mm package, pre‑calibrated and ready‑to‑use
- Robust library support in Arduino, CircuitPython, and PlatformIO
Because it bridges physics, engineering, data science, and design, the BME280 is a cornerstone for STEAM curricula empowering students to turn abstract environmental concepts into tangible, data‑driven inventions.
