Thanks to Josh Levine for bringing this barometer module to our attention.
| Honeywell SDX15D4 for absolute pressure |
Use an absolute air pressure (barometric) sensor to determine:
- altitude, with ground level atmospheric pressure set at takeoff time.
| Honeywell 163PC01D36 for differential pressure |
A differential pressure sensor is used:
- in a Pitot tube to measure air speed.

Our experience: we ordered four units in August 2007, and they were delivered within a day. The UK representative, Nick Belson Design Limited, even added a small PCB (shown above) for good measure. Very impressive!
