Barometers -  Note: the above charge monitors are really just toys. Although fun and interesting, their arbitrary zero limits them to monitoring changing fields and makes them inferior to a mechanical field mill. . . .  [Copyright 1998 Wenzel Associates, Inc.]

 

1-Wire Barometer -  This article describes details for constructing a 1-Wire Barometer which will work on a Dallas Semiconductor Corporation 1-Wire network. The reason for this second version is that the transistor level-changer of the original design was found to be temperature sensitive. If you have constructed the original. . .  [David W. Bray]

 

1-wire barometer -  This is a description and the ongoing story of my project to build a 1-wire barometer based on the MPX4115A. . .  [Philip Gladstone]

1-Wire Barometer--5/10 Volt Design vrs 2 -  This article describes details for constructing a 1-Wire Barometer which will work on a Dallas Semiconductor Corporation 1-Wire network. It differs from the popular Version 1. 1a in that it has more than twice the resolution. As with 1-Wire Barometer Version 1. 1a, this design uses a Motorola MPX4115 Silicon Pressure Sensor, a Dallas Semiconductor DS2438 Smart Battery Monitor (to perform 1-Wire analog to digital conversion), an operational Amplifier, two voltage regulators, two diodes, a LED, and several resistors and capacitors. . . .  [David W. Bray]

 

1-Wire Barometer--5/10 Volt Design Vrs 3 -  This article describes details for constructing a 1-Wire Barometer which will work on a Dallas Semiconductor Corporation 1-Wire network. This design differs from the popular Version 1. 1a in that it has more than twice the resolution. . . .  [David W. Bray]

 

Altimeter Project -  Making a altimeter using the Basic Stamp II. I finally got my Basic Stamp Pocket Altimeter done. My first version of my altimeter used a linear equation , which i found is not really accurate at all. So i got a PAK II math coprocessor to calculate the altitude. Although the PAK II worked like a charm in my old bulky altimeter, I wanted to make one that was pocket size and the PAK II was just too big. In pocket altimeter I overcame the Stamp's lack of math capabilties by using a method known as linearization to do the calculations. . . .  [Shaun Wilson]

 

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. . .  [David W. Bray]

 

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. . .  [Charles Wenzel (unless otherwise noted)]

 

Electronic Barometers -  . . .  [Charles Wenzel, designer (unless otherwise noted)]

 

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, . . .  [James Padfield]

 

K2LMG/W5EUT 1-Wire Barometer--5/10 Volt Design vrs 2 -  This article describes details for constructing a 1-Wire Barometer which will work on a Dallas Semiconductor Corporation 1-Wire network. It differs from the popular Version 1. 1a in that it has more than twice the resolution. As with 1-Wire Barometer Version 1. 1a, this design uses a Motorola MPX4115 Silicon Pressure Sensor, a Dallas Semiconductor DS2438 Smart Battery Monitor (to perform 1-Wire analog to digital conversion), an operational Amplifier, two voltage regulators, two diodes, a LED, and several resistors and capacitors. . . .  [David W.

K2LMG/W5EUT 1-Wire Barometer--5/10 Volt Design Vrs 3 -  This article describes details for constructing a 1-Wire Barometer which will work on a Dallas Semiconductor Corporation 1-Wire network. This design differs from the popular Version 1. 1a in that it has more than twice the resolution. . . .  [David W. Bray]

 

Liquid Barometer -  Have you ever noticed how those technical-looking aneroid barometers in the stores all indicate a different pressure? And when you. . .  [Charles Wenzel (unless otherwise noted)]

 

Small, portable altimeter operates from a single cell -  06/21/01 EDN Design Idea   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 compen. . .  [by Todd Owen, Linear Technology Corp, Milpitas, CA]
