Thanks to Bosch, now we’ve got a high-precision environmental sensor at even lower cost, the Grove – Barometer Sensor(BMP280). It is based on their new BMP280 sensor, which is an upgraded version of the old BMP180 used in Grove – Barometer Sensor (BMP180). The module provides precise measurement of barometric pressure and temperature in the environment. The air pressure can be measured in a range from 300 hPa to 1100hPa with ±1.0 hPa absolute accuracy. As for the temperature the sensor works perfectly for temperatures between - 40 and 85 with an accuracy of ±1.
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. If you go with I2C, the board also provides 2 I2C addresses for you to select as you want.
Note: As the sensor is quite sensitive to the environmental conditions, please DO NOT touch it with your fingers.

由於博世,現在我們已經有了一個高精度的環境傳感器以更低的成本,在樹叢-晴雨表傳感器(BMP280) 。 它是基於他們的新BMP280傳感器,這是在使用舊BMP180的升級版林-晴雨表傳感器(BMP180) 。 該模塊提供了在環境大氣壓和溫度的精確測量。的空氣壓力可在範圍從300 hPa到1100hPa與±1.0百帕絕對精度來測量。作為溫度傳感器完全適用的溫度- 40和85±1的精度。
由於對測量壓力的測量精度高,並與高度的壓力變化,就可以計算±1計的精度,這使得它精確高度表以及海拔高度。這個模塊的另一個偉大的事情是,你甚至不需要擔心I2C碰撞,因為它提供I2C和SPI接口。使用SPI,簡單地解焊接背面的焊接區。如果用I2C去,該主板還提供了2個I2C地址供您選擇,只要你想。
注:由於傳感器是環境條件非常敏感,請不要用手指觸摸它。
