Grove - Barometer Sensor(BME280)
Grove - Temp&Humi&Barometer Sensor (BME280) is a breakout board for Bosch
BMP280 high-precision, low-power combined humidity, pressure, and temperature
sensor. This module can be used to measure temperature, atmospheric pressure and
humidity accurately and fast. As the atmospheric pressure changes with altitude, it can
also measure approximate altitude of a place. It can be connected to a microcontroller
2
with I C (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. Using the sensor is easy. For Seeeduino (compliant with Arduino), just connect this
breakout board using Grove cable to I2C Grove connector. Then, use the provided
library and example code from GitHub. If you are using an Arduino either use Base
Shield v2.0 or simply connect the VCC pin to the 5V voltage pin, GND to ground, SCL to
I2C Clock (Analog 5) and SDA to I2C Data (Analog 4).
Typical applications: Enhancement of GPS navigation, outdoor/indoor navigation,
weather forecast, or any other project that requires accurate atmospheric pressure
reading.
