Re: Arduino code for the MPL115A1 Pressure Sensor (SPI)

Phil, I can really only offer generic advice. The value that you're showing (7.25 psi) is what you get when the software reads zeros off the device. The range is 50-115 kPa which is 7.25-16.68 psi. So either the part is dead or not connected correctly. Here are some suggestions: 1. Check the PCB. I ...

Re: SPI interfacing to the MPL115A1 pressure sensor?

Hi Phil,

I put together an Arduino sketch that uses this device with examples for how to read temperature and pressure and how to calculate altitude.

Hope this is helpful,
Jeremiah

Arduino code for the MPL115A1 Pressure Sensor (SPI)

This sketch shows how to read pressure and temperature from the MPL115A1 Pressure Sensor (SPI version) and as a bonus throws in a simple altimeter. I got the breakout board with this device on it yesterday and found the provided sample code a little complex for my simple mind. This sketch should be ...
