MS5561C Pressure Sensor Completes 24 Mile Skydive
Felix Baumgartner recently set a world record for skydiving. Jumping out of a helium balloon from a height of 24 miles, he landed ten minutes later after free falling at speeds up to 834.4 mph for about 4 minutes and then parachuting to the ground. This project was sponsored by Red Bull, an energy drink sold by the Austrian company Red Bull GmbH.
Strapped to Mr. Baumgartner’s left arm of his space suite was an ALTITRACK™ sport altimeter boasting an analog face but utilizing the highest technical and durable digital components for accuracy that surpasses every other mechanical sport altimeter currently available.
It was the MS5561C micro-pressure altimeter sensor that was packaged with the ALTITRACK™ sport altimeter to provide key altitude measurements. The MS5561C is an SMD-hybrid device that uses a three-wire serial interface for communication. The module dimensions of 4.75 mm x 4.25 mm and a height of only 1.6 mm allows for up-to-date SMD design. This low power, low voltage device features automatic power down (ON/OFF) switching. The MS5561C was selected for this application due to its high accuracy, ability to withstand extreme cold, excellent negative g force resistance and low sensitivity to vibration caused by supersonic sound waves.
