The module includes a high linearity barometric pressure sensor and a high resolution temperature output, allowing implementation of an altimeter/thermometer without any additional sensors. Different operation modes allow the user to optimize for conversion speed or current consumption. The module is designed for use with a large variety of microcontrollers with different voltage requirements.
For this project I connected it to the Parallax Board Of Education with a Parallax serial LCD as shown in the image below. It can send data to a computer in a serial terminal window or to and LCD as you’ll see in the video.
I used three different versions of Spin code to display the data which can be downloaded here:

This module is ideal for use on hobby aircraft or for data logging on a robot.
Enjoy the video and… keep on hackin!
