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. . .  [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 lightning monitor -  This article describes the construction of an experimental lightning monitor for use with the Dallas Semiconductor 1-wire bus. This monitor provides real-time data on lightning activity by counting the number of lightning strikes in the area. This device is designed to either. . . 

 

1-wire weather station -  The Dallas Semiconductor 1-Wire Weather Station (WS-1) was created in 1998 as a demonstration tool of 1-Wire technology. It was featured in the June 1998 issue of Sensors magazine. The weather station reports wind speed, direction, and temperature to a PC connected via its RS-232 serial port. . .  [Maxim Integrated]

 

1-wire weather station  -  This article presents a 1-Wire® weather station that solves many of these problems by transmitting both power and bi-directional data over a single twisted-wire cable. . .  [Maxim Integrated]

 

1-Wire Weather Station (Dan Awtrey) -  To accurately describe current weather conditions and predict coming events, meteorologists need reliable data. Much of this information is collected from weather stations, and forecasters would like to have more of them. The problem is that conventional meteorological instrument systems are inefficient and expensive. . . .  [Dan Awtrey, Dallas Semiconductor]

 

741 Based Light Sensor -  The circuit as shown act as a light sensor. Under normal conditions the resistance of the LDR is high, keeping pin 2 low. When light falls onto the LDR the resistance drops to a couple hundred ohms and triggers pin 2 high which biases the base of Q1 via pin 6 and R4 and in turn activates the relay. . .  [Tony van Roon's circuit]

 

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]

 

Amateur weather station to APRS interface ALWXI-01 -  Before putting the WS APRS interface into operation the network parameters should be set. This can be done using a PC connected to the ALWXI-01 through a serial interface. Any terminal emulating SW supporting TTY, VT52 or VT100 mode (HyperTerminal, WTT, etc. ) will do the job just fine. Connect the interface to the PC using a three wire cross-connected serial cable (RXD<-->TXD, TXD<-->RXD, GND<-->GND). . .  [by Aleksander Stare]

 

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]

 

AN-256: Circuitry for Inexpensive Relative Humidity Measurement -  Application Note. . .  [National Semiconductor]

 

AN-829: Environmental Compensation on the AD7142: the Effects of Temperature & Humidity on Capacitance Sensors -  AN-829 Analog Devices App Note. . . 

 

Anemometer Circuit -  A totally Electronic circuit to measure Air Flow, Zero to 250 feet per Minute  That's only 2. 84 MPH, But MAYBE it can be Modified for other Rates of Air Flow. . . .  [G.L. Chemelec, designer]

 

Anemometer Fights Dust -  08/30/01  EDN Design Idea   As higher levels of power dissipation underscore the need for cooling, andfans are finding their way into small electronic enclosures. The dust that fans pull into these enclosures can, however, cause major problems for high-reliabi. . .  [by Jim Christensen, Maxim Integrated Products, Sunnyvale, CA]

 

Another One-Transistor Cloud Charge Monitor -  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.]

 

Atmospheric Disturbance Monitor -  . . .  [electronic design by Lennie Zink]

 

Ball Lightning Detector -  Lightning in a jar. . .  [electronic design by Lennie Zink]

 

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.]

 

Cloud Charge Monitor -  The Cloud Charge Monitor is an extremely sensitive device capable of detecting subtle (and not-sosubtle) changes in the accumulated charge overhead. The device consists of a charge-sensing antenna, a 60 Hz notch filter, a self-zeroing integrator, a signal limiter, and a leakage zero adjustment. . .  [Charles Wenzel (unless otherwise noted)]

 

Connection Tester -  A low resistance ( 0. 25 4 ohm) continuity tester for checking soldered joints and connections. . .  [Andy Collison's website]

 

Dew Sensor -  Dew (condensed moisture) adversely affects the normal performance of sensitive electronic devices. A low-cost circuit described here can be used to switch off any gadget automatically in case of excessive humidity. At the heart of the circuit is an inexpensive (resistor type) dew sensor element. Although dew sensor elements are widely used in video cassette players and recorders, these may not be easily available in local market. . .  [designer's name not found]

 

Dew-Point Sensor -  This simple but highly responsive circuit to protect equipment from dew (condensed moisture) can also be used to prevent condensation on surfaces like cold water pipes and windows. . . .  [© EFY Enterprises Pvt. Ltd. All rights reserved.]
