Crash Course: Using the BME280 Environmental Sensor Module
Objective
Teach learners how to use the BME280 sensor module to measure temperature, humidity, and atmospheric pressure, and integrate its readings with a TRIOE microcontroller.
Materials Required
- BME280 Sensor Module
- TRIOE
- Breadboard and jumper wires
- USB cable for programming the TRIOE
- Computer with Arduino IDE installed
Steps
1Understand the BME280 Sensor
- The BME280 measures: Temperature in degrees Celsius, Humidity as a percentage, Pressure in hPa (hectopascal).
- Communication Protocols: I2C (2-wire communication with SDA and SCL), SPI (optional for advanced users).
2Set Up the Circuit
- Connect the VCC pin to the TRIOE's 5V.
- Connect the GND pin to the TRIOE's GND.
- Connect the SDA pin to the TRIOE's A4 pin.
- Connect the SCL pin to the TRIOE's A5 pin.
3Install the BME280 Library
- Open the Arduino IDE.
- Go to Sketch > Include Library > Manage Libraries.
- Search for 'Adafruit BME280' and install the library.
- Also, install the 'Adafruit Unified Sensor' library, if prompted.
