NSLU2 wind meter. 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.
Live sensor data was captured after 10:00 a.m. Downloads: Hardware: Software for Arduino: wheater_app_110807.zip.
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. That sensor is using the Quozl's Temperature Sensor design which is very simple and does not use the full power of the 1-wire bus.
