based on Bosch BME280, we made this low-cost and high-precision environmental sensor -- the Grove - BME280 Environmental Sensor (Temperature Humidity Barometer). This BME280 supports both I2C and SPI communication and we provide the Arduino BME280 library.

 

Grove BME280 provides a precise measurement of not only barometric pressure and temperature, but also the humidity in the environment. The air pressure can be measured in a range from 300 hPa to 1100hPa with ±1.0 hPa accuracy, while the sensor works perfectly for temperatures between - 40℃ and 85℃ with an accuracy of ±1℃. As for the humidity, you can get a humidity value with an error less than 3%.

Owing to its high accuracy on measuring the pressure, and the pressure changes with altitude, we can calculate the altitude with ±1 meter accuracy, which makes it a precise altimeter as well.

Another great thing about this module is that you don’t even need to worry about the I2C collisions as it provides both I2C and SPI interfaces. To use SPI, simply de-solder the bonding pads on the back of this BME280 breakout board. If you go with I2C, the board also provides 2 I2C addresses for you to select as you want.  

BME280 VS. BMP280

BME280 is often confused with BMP280. Simply speaking, BME280 is a three-in-one environmental sensor that measures temperature, pressure, and humidity. BMP280 can only measure temperature and pressure, and cannot measure humidity. So, if you need better and more comprehensive monitoring of the environment, we recommend you buy the BME280, if you do not need to measure the humidity, we recommend you buy the cheaper Grove - Barometer Sensor (BMP280)

Features

High accuracy, absolute accuracy of ±1.0 hPa for pressure, ±1 accuracy for temperature and ±3% for humidity

Easy-to-use Grove Compatible Interface

Supports both I2C and SPI communication

Can be used as an altimeter with the accuracy of ±1 meter

Note

As the sensor is quite sensitive to the environmental conditions, please DO NOT touch it with your fingers.
