描述

感謝博世,現在我們已經有了一款成本更低的高精度環境傳感器 Grove - 氣壓計傳感器(BMP280) 。它基於其新型 BMP280 傳感器,該傳感器是 格羅夫 - 氣壓計傳感器(BMP180)中 使用的老式 BMP180 的升級版本 。該模塊可以精確測量環境中的氣壓和溫度。空氣壓力可以在 300hPa 至 1100hPa 範圍內測量,精度為±1.0hPa。至於溫度,傳感器完美適用於-40 至 85 之間的溫度,精確度為±1。

由於測量壓力的精度高,壓力隨海拔高度變化,我們可以計算出±1 米精度的高度,這也是精確的高度計。這個模塊的另一個好處是,你甚至不需要擔心 I2C 衝突,因為它提供了 I2C 和 SPI 接口。要使用 SPI,只需將背面的焊盤去焊即可。如果您使用 I2C,則該板還提供了 2 個 I2C 地址供您根據需要進行選擇。

注意:由於傳感器對環境條件非常敏感,請勿用手指觸摸。

Description

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.
