PRODUCT DETAILS

Note

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

Grove - Temp&Humi&Barometer Sensor (BME280) is a breakout board for Bosch BMP280, a high-precision, low-power combined humidity, pressure, and temperature sensor.

Features

  • High-performance environmental detection: With the help of BME280 module, it can simultaneously detect temperature and humidity, air pressure, to achieve a stronger detection effect.
  • Robust measurement range: The sensor can operate normally from -40 to 85 degrees Celsius. And atmospheric pressure sensor measurement range is from 300 to 1100 hPa.
  • Higher measurement accuracy: Only ±1.0°C error when measuring temperature, measure humidity with ±3% accuracy and measure atmospheric pressure with ±1.0 hPa accuracy.
  • Grove unified socket: The sensor ensures "Plug and Play" and could be versatile for various applications.

Description

Grove - Temp&Humi&Barometer Sensor (BME280) is a breakout board for Bosch BMP280, a high-precision, low-power combined humidity, pressure, and temperature sensor. 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 of less than 3%. As the atmospheric pressure changes with altitude, it can also measure approximate altitude of a place. We can calculate the altitude with ±1 meter accuracy, which makes it a precise altimeter as well. It can be connected to a microcontroller with I2C (integrated with Grove socket) or through SPI bus. We have also provided highly abstracted library to make this more product easier to use.

The BME280 is an upgraded version of BMP180, and BME280 gets dramatic improvements from BMP180. BME280 comes with a smaller footprint, lower power consumption, lower noise measurements, higher resolutions for pressure and temperature, lower RMS noise, newly added SPI bus, more measuring modes, higher measuring rate, and newly added filter against environmental interference. Since the atmosphere pressure reading is affected by altitude and temperature, we have added compensation features. Hence, Grove - Temp&Humi&Barometer Sensor (BME280) will be more reliable in providing precise temperature, atmospheric pressure values, humidity and approximate altitude data.
