Frequently Asked Questions (FAQ)

  • Q: How do I connect a BME280 with an Arduino?

    A: You can easily wire this breakout to any microcontroller, we'll be using an Arduino. For another kind of microcontroller, as long as you have 4 available pins it is possible to 'bit-bang SPI' or you can use two I2C pins, but usually those pins are fixed in hardware. Just check out the library, then port the code. more

  • Q: How do I get started with a BME280 sensor?

    A: The BME280 is an integrated environmental sensor developed specifically for mobile applications where size and low power consumption are key design constraints. The unit combines individual high linearity, high accuracy sensors for pressure, humidity and temperature in an 8-pin metal-lid 2.5 x 2.5 x 0.93 mm³ LGA package, designed for low current consumption (3.6 μA @1Hz), long term stability and high EMC robustness. more

  • Q: Where can I find an Adafruit BME280 breakout board tutorial?

    A: This precision sensor from Bosch is the best low-cost sensing solution for measuring humidity with ±3% accuracy, barometric pressure with ±1 hPa absolute accuraccy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with ±1 meter or better accuracy! more

  • Q: How do I use a BME280 with a Raspberry Pi?

    A: In this tutorial, we’re going to use a multifunctional module that enables the Raspberry Pi to read temperature, humidity, and barometric pressure simultaneously. Soldering is required in this project! As shown in the above picture, this part comes with a separate pin header so we need to solder them onto a breadboard. more

  • Q: Where can I find a wire up diagram for the BME280 and ESP8266?

    A: Since its launch in 2014, ESP8266 has revolutionized the IoT space by offering an extremely cost-effective and programmable WiFi-enabled microcontroller to hobbyists and professionals, thereby opening the doors to all kinds of everyday objects and sensors to the internet. more

  • Q: How do I use I2C with a BME280 sensor?

    A: The BME280 supports either SPI or I2C interface to communicate with the micro controller. Because of the small size of the sensor, the best way to use this sensor is with a breakout board. The Adafruit breakout board is used here. In this hookup we are only connecting one device to the Arduino using the I2C bus. We can use either address (0x77 or 0x76). It reads the barometric pressure, humidity and temperature and displays it on the console. more

  • Q: Where can I download the BME280 library?

    A: Provides an Arduino library for reading and interpreting Bosch BME280 data over I2C, SPI or Sw SPI. Additional environment calculation functions are provided. ESP and BRZO are now supported. more

  • Q: Where can I compare BME280 with BMP280 sensors?

    A: Device driver interface for the Bosch BMP280 and BME280 sensors. BMP280 and BME280 measure temperature in centi °C and pressure in Pa. BME280 can also measure relative humidity in %.For more information, see the datasheets: more

  • Q: How do I get started with a BME280 breakout board?

    A: The BME280 Breakout Board is the easy way to measure pressure and humidity, and without taking up a lot of room. It gives you easy to solder 0.1" headers, runs I2C or SPI, takes measurements at less than 1mA and idles less than 5uA (yes, microamps!). more

  • Q: How can I use Python to read a BME280 sensor?

    A: The BME280 device is a digital barometric pressure sensor and is a slightly upgraded version of the BMP180. This is available on a small module which provides access to the sensor via the I2C interface. This allows us to easily connect it to the Raspberry Pi and read the data using Python. The BME280 provides temperature, pressure and humidity. more

  • Q: Where can I find a BME280 calibration tutorial?

    A: Zero point calibration of DS18B20. The best resolution of the DS18B20 is 0.06°C, giving highly quantised data. We can average over time and derive a mean temperature with a standard error of <0.001°C, however without understanding a lot more about how the DS18B20 internally handles analogue-to-digital conversion and rounding, the best error I am willing to quote is half the native resolution, or 0.03°C. more

  • Q: How do I wire a BME280 with a NodeMCU?

    A: This module provides a simple interface to BME280/BMP280 temperature/air presssure/humidity sensors (Bosch Sensortec). more

  • Q: How can I read the BME280 I2C address?

    A: The default I2C address is set to 0x77 - (which is also default for BMP180). I have noticed there are several variants of the sensor. Mine however is running on 0x76 address (many thanks to I2C scanner) more
