描述

MPL3115A2 海拔 大氣壓力感測器模組

MPL3115A2 海拔 大氣壓力感測器模組 是MEMS壓力傳感器，可提供30cm以內的高度數據（啟用過採樣功能）。感測器輸出由高分辨率的24位ADC數字化並通過I2C傳輸，這意味著可以輕鬆地與大多數控制器接口。壓力輸出可以以  Pascal 的分數來解析，而海拔高度可以以米的分數來解析。該設備還提供以攝氏度為單位的12位溫度測量。

該分線板通過將必要的引腳分接到標準的 2.54mm 間距接頭上，從而使使用該小型設備的原型變得容易。該板還具有使設備正常工作所需的所有無源組件，因此您只需將其連接到某物討論I2C並開始工作！

Altitude/Pressure Sensor Breakout – MPL3115A2

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!
