Shelly Park Weather Station | Howick, Auckland, New Zealand 1-wire projects - Koos van den Hout 1-wire (or one-wire, but I prefer the name Maxim uses) is a simple bus to connect electronic devices. Other sites can explain it much better: But basically it is a way to create a simple network of devices that can communicate with one master device aimed at low-speed communications with measuring devices like thermometers and output devices like relays. The minimal 1-wire network has two wires: one for ground and one for data and power. Simple devices can be powered using parasitic power derived from the data line. The network of 1-wire devices is also known as 'Microlan'. All 1-wire devices have unique addresses and an in my opinion very neat protocol is used to discover devices. I got interested in 1-wire because at work we had a 4-channel thermometer based on 1-wire sensors which we now use to monitor rack temperatures. I quite liked the whole idea of 1-wire and how it could make hooking up temperature and other sensors to the computer simple and cheap. Temperature logging Links
Arduino: Weather-Shield – schematics, layout, code, … – everything you need | Zipfelmaus - Blog I’ve been working quite a while on my weather station project. Since the first version of the hardware had some bugs, I redesigned the electronics from scratch and created a weather shield for the Arduino. So here it is: Overview: The shield has several sensors: - barometric pressure sensor – BMP085, from Bosch, I2C interface - humidity sensor – SHT11, from Sensirion, proprietary serial interface - light sensor, connected to an ADC-In - DIO, e.g. for a wind meter - ADC-Ins for measuring the voltage in the solar system part of the system Apart from the weather shield I also attached a Xbee shield in order to transmit data wirelessly to a server PC, because I want to display the data on a website. Before 10:00 a.m. there was no data available. Downloads: Hardware: Software for Arduino: wheater_app_110807.zip
