描述

SparkFun Altitude/Pressure Sensor Breakout – MPL3115A2 高度/壓力/溫度 多功能 MEMS 感測器

美國 SparkFun 原裝進口

MPL3115A2是一款MEMS壓力傳感器,可提供30cm以內的高度數據(啟用過採樣)。傳感器輸出通過高分辨率24位ADC進行數字化,並通過I2C進行傳輸,這意味著與大多數控制器的連接非常簡單。壓力輸出可以用帕斯卡的分數輸出來解決,而高度可以在幾分之一米內解決。該器件還提供以攝氏度為單位的12位溫度測量。

這個接線板可以很容易地使用這個微型設備的原型,把標準的0.1“引腳連接到一個標準的0.1”的接頭上,板子上也有所有的被動元件來使設備正常工作,所以你可以簡單地把它連接到談到I2C並開始工作!

原廠技術文件與範例


Life has its ups and downs, so why not measure them? The MPL3115A2 is a MEMS pressure sensor that provides Altitude data to within 30cm (with oversampling enabled). The sensor outputs are digitized by a high resolution 24-bit ADC and transmitted over I2C, meaning it’s easy to interface with most controllers. Pressure output can be resolved with output in fractions of a Pascal, and Altitude can be resolved in fractions of a meter. The device also provides 12-bit temperature measurements in degrees Celsius. This breakout board makes it easy to prototype using this tiny device by breaking out the necessary pins to a standard 0.1″ spaced header. The board also has all of the passive components needed to get the device functioning, so you can simply connect it to something that talks I2C and get to work!
