描述

Grove – Temp&Humi&Barometer Sensor (BME280) 溫濕度含氣壓計感測器 三合一環境傳感器

Grove – Temp&Humi&Barometer Sensor (BME280) 三合一環境傳感器,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,它比Grove 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)都要好。

該模組不僅提供氣壓和溫度的精確測量,而且還提供環境中的濕度。空氣壓力可以在300hPa到1100hPa之間的範圍內進行測量,精度為±1.0hPa,而傳感器在-40到85之間的溫度下完美工作,精度為±1。至於濕度,你可以得到一個濕度值,誤差小於3%。由於測壓精度高,壓力隨海拔高度變化,我們可以計算海拔高度精度±1米,這也是一個精確的高度計。這個模組的另一個好處是,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,則電路板還提供了2個I2C地址供您根據需要進行選擇。

BME280是BMP180的升級版,BME280從BMP180獲得了巨大的改進。BME280尺寸更小,功耗更低,噪聲測量更低,壓力和溫度分辨率更高,RMS噪聲更低,新增的SPI總線,更多的測量模式,更高的測量速率以及新增加的抗環境干擾的濾波器。由於大氣壓力讀數受高度和溫度的影響,我們增加了補償功能。因此,格羅夫 – 氣壓計傳感器(BME280)在提供精確的溫度,大氣壓力值,濕度和近似高度數據方面將更加可靠。

注意由於傳感器對環境條件非常敏感,請勿用手指觸摸。

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

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