MPL115A2 - I2C Barometric Pressure/Temperature Sensor POL_Tic Stepper Motor Controllers Arduino Add-on FilesThis pressure sensor from Freescale is a great low cost sensing solution for measuring barometric pressure. At 1. 5 hPa resolution, it's not as precise as our favorite pressure sensor, the BMx280 series , which has up to 0. 03 hPa resolution so we don't suggest it as a precision altimeter. However, it's great for basic barometric pressure sensing. The sensor is soldered onto a PCB with 10K pull up resistors on the I2C pins. This chip is good for use
