The DEMOAPEXSENSOR is an experimental demonstration board focused on pressure sensors with a variety of applications. Applications include: Altimetery, Barometery, Waterlevel, Tilt, Free Fall, and Temperature Sensing. It incorporates the MPXM2102A, MPXV5004G, and MPL115A2 pressure sensors and the MMA7361L inertial sensor. The demo incorporates an LCD display to provide standalone functionality to the user. Altitude is resolved to 1m intervals, weather conditions can be observed over time, and liquid levels up to 40cm can be measured. It is a great platform for testing algorithms for the various applications.
