Barometer Circuits

1-Wire Barometer. Part 1 -  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. __ Designed by David W. Bray

1-Wire Barometer. Part 2 -  The design presented in the schematic above is not the only possible barometer that can be constructed with this printed circuit board. Not only is the printed circuit board designed to be modified for different voltage sources and 1-wire networks, but the values of the resistors can be modified for different ranges of barometric pressure and resolutions. __ Designed by David W. Bray

1-Wire Barometer. Part 3 -  Suggestions on Final Calibration Getting your barometer accuracy calibrated will take adjustment over several cycles of barometric pressure change.  The initial calibration will not be accurate unless your MPX4115 has the same output vs pressure __ Designed by David W. Bray

A Barometer That Measures Your Height -  31-Jul-09 -Design News:   Here's a weather instrumentthe Dodecahedral Barometerthat can actually determine how tall you are by reading the barometric pressure between your head and your feet.  Mark Thoren notes that his gadget was inspired by the release of some new electronic products.  The first is a Serta model 270 __   Gadget Freak-Case #145

Barometer WiFi ESP8266-Lua -  Glass & Brass barometer is precise digital wifi barometer with pressure sensor BMP085 or BMP180 and wifi module ESP8266.  It's a miniature web server. By mapping ports of your router, you can connect to it from anywhere on the world.  The barometer uses Lua software and trendy vector graphics format SVG.  The barometer is particularly interesting for its graphic design.  In terms of program, this is simple. Thanks to this, barometer is quite fast and stable, which was my goal. __ Designed by Pavel Janko

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. __ Contact: Charles Wenzel of Wenzel Associates, Inc.

Lua Barometer WiFi ESP8266 -  Glass & Brass barometer is precise digital wifi barometer with pressure sensor BMP085 or BMP180 and wifi module ESP8266.  It's a miniature web server. By mapping ports of your router, you can connect to it from anywhere on the world.  The barometer uses Lua software and trendy vector graphics format SVG.  The barometer is particularly interesting for its graphic design.  In terms of program, this is simple. Thanks to this, barometer is quite fast and stable, which was my goal. __ Designed by Pavel Janko

Weather station with pressure reading, relative humidity, indoor & remote temperature reading -  Weather station with pressure reading, relative humidity, indoor & remote outdoor temperature display.  Both Celsius or Fahrenheit & mbar/hPa or mm Hg  supported.  With calendar & clock.  Easy 3-button user-menu.42 hour-history display (curve).  Auto-memory & display of all high and low-values.  PIC 18F452 running at 4 MHz, sleep mode. __ Designed by Michel Bavin

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 version (V1.0) you can modify it according to the diagram shown below.  This involves removing the transistor and 5 resistors, then rewiring it with 6 new resistors. __ Designed by 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 __ Designed by 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. __ Designed by 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. __ Designed by 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. __ Designed by 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. __ Designed by 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.   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 version (V1.0) you can modify it according to the diagram shown below.  This involves removing the transistor and 5 resistors, then rewiring it with 6 new resistors. __ Designed by 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 __ Contact: Charles Wenzel of Wenzel Associates, Inc.

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, __ Designed by 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. __ Designed by David W. Bray

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. __ Designed by 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 __ Contact: Charles Wenzel of Wenzel Associates, Inc.
