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!

人生有起有落,所以為什麼不衡量呢?該MPL3115A2是MEMS壓力傳感器,提供高度數據30厘米之內(啟用過採樣)。傳感器輸出由高分辨率24位ADC數字化,並通過I2C傳輸,這意味著它很容易與大多數控制器的接口。壓輸出可以在一個Pascal的分數輸出解決,海拔高度在一米的分數來解決。該裝置還提供了以攝氏度12位的溫度測量。
這個接口板可以很容易地通過打破必要的引腳為標準0.1“間距頭使用這種微型設備原型,該主板還擁有所有來獲得設備運轉,所需的無源元件,所以你可以簡單地把它連接到的東西,討論I2C和去工作吧!
