1 Wire Barometer - By using a dual voltage supply, instrument
precision and/or instrument range can be improved without adding
significantly to the parts count.… [from A.G. Miller's web site] |

1-Wire Barometer (David Bray) - This article describes details
for constructing a 1-Wire Barometer which will work on a Dallas
Semiconductor Corporation 1-Wire network....(Designer is David Bray]

1-wire barometer (gladstone) - This is a description and the
ongoing story of my project to build a 1-wire barometer based on the
MPX4115A. (added 08/08/08) |

Altimeter/Variometer for free flying - A handheld instrument
intended for the paraglider and hang glider pilot. Displays altitude above
sea level, altitude above take off, climb and fall rates, flight time,
maximum altitude. Software-calibrated, features a backlit LCD, internal
rechargeable batteries and internal charge regulator. Uses a Basic Stamp
II. [Manfred Mornhinweg] |

An Experimenter's 1-Wire Barometer - This article describes details for
constructing a 1-Wire Barometer which will work on a Dallas Semiconductor Corporation
1-Wire network…(circuit added 08/08) |

Basic Stamp Based Altimeter - A method of determining altitude is by
use of barometric pressure; however, it is not done without difficulty. The
relationship of pressure vs. altitude is not a linear one, it is actually a fairly
complex one, which army came up with in 1930's. This is
equation for calculating.... (added 6/06) |

Electronic Barometer - Sooner or later the weather hobbyist wants an
electronic barometer, the main advantage being that it can be read automatically by a
computer, chart recorder, or other data taking system. Most electronic barometers use
some sort of strain gauge transducer to directly convert pressure to voltage and true
weather bureau performance can be difficult to achiever....(design idea added

Home-Brew electronic altimeter - A while back, I decided I wanted an
altimeter to record how high my rockets were flying. I didn't want to buy one, since
a) they aren't cheap (at least, not the ones which do everything I want them to do),
and b) buying one is far too easy. I considered the CP Technologies kit, which is
based on the Missile Works RRC2,....(added 6/07) |

Liquid Barometer - Have you ever noticed how those technical-looking aneroid
barometers in the stores all indicate a different pressure? And when you....(design

Small Portable altimeter operates from a single cell - 06/21/01 EDN-Design
Ideas Some sports enthusiasts want to know altitude changes from an initial
elevation. A small, lightweight, portable altimeter is easy to design using modern
micromachined pressure transducers. Inverting barometric pressure and compensating for
nonlinearities in air-pressure changes…several designs included, scroll to find this
one.... [Design Idea by Todd Owen, Linear Technology Corp, Milpitas, CA] |
