描述

感謝博世,現在我們有了三合一,低成本和高精度的環境傳感器 Grove-Temp&Humi&氣壓計傳感器(BME280)

 

它基於他們的新型 BME280 傳感器,該傳感器甚至比格羅夫 - 氣壓計傳感器(BMP280)中 使用的 BMP280 以及 Grove - 氣壓計傳感器(BMP180)中 使用的任何其他以前的版本 (如 BMP180)更加優秀

 

該模塊不僅可以精確測量氣壓和溫度,還可以測量環境中的濕度。空氣壓力的測量範圍為 300 hPa 至 1100 hPa,精度為±1.0 hPa,而傳感器在-40 至 85 的溫度範圍內完美工作,精確度為±1。至於濕度,您可以得到一個誤差小於 3%的濕度值。

 

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。

 

特徵

  • 高精度,壓力的精度為±1.0 hPa,溫度精度為±1,濕度精度為±3%

  • 易於使用的 Grove 兼容界面

  • 支持 I2C 和 SPI 通信

  • 可以用作±1 米精度的高度計

 

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 three-in-one, low-cost and high-precision environmental sensor, the Grove - Temp&Humi&Barometer Sensor (BME280).


It is based on their new BME280 sensor, which is even superior to BMP280 used in Grove – Barometer Sensor (BMP280), and any other former versions like BMP180 used in Grove – Barometer Sensor (BMP180).


The module provides 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. If you go with I2C, the board also provides 2 I2C addresses for you to select as you want.


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 accuracy of ±1 meter


Note

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